Greenhouses can mean more heat, more shade, supplemental lights, insect screens, etc. But let’s look at some common-sense approaches and deciding factors one can use in basic site planning.

Insect Screens for Greenhouses All You Need to Know

August 2022

Summer may be coming to a close as cooler temperatures seem like a promising relief for many parts of the country.  But one thing remains along with the oppressive heat…bugs!  For many of us, insects don’t disappear as fall approaches.  Annoying critters can destroy our bountiful produce, beautiful blooms, and lush foliage.  Growing concerns over the use of pesticides dictate demand for a cleaner, more organic option.  The proven answer is insect screens, and no modern greenhouse should be installed without the proper insect barrier.

Insect screens are strong, UV stabilized, lightweight, easy to install, transparent, and easy to clean, making them the perfect choice for today’s greenhouse.  Correctly installed, they prevent insect penetration while still providing maximum possible airflow.  Screening your intake vents will produce dramatic results, but ALL greenhouse openings should also be screened. 

Now let’s talk about screen varieties and how to choose!  Anti-insect screen choices are differentiated by hole size or mesh size. Hole size accuracy and strong UV-resistant yarns will ensure the highest quality products from your greenhouse.   You should choose mesh size according to the insects prevalent in your area.  You want to target your mesh size according to the smallest pesky insect.  The higher the mesh percentage, the smaller the insect that is prevented from entering your greenhouse.  An added bonus with insect screens is some degree of shading.  The highest mesh percentages available can provide as much as 50% shade. 

Here is a handy chart that shows the size of some of the most common insects:

Next, let’s take a look at the different mesh varieties that Gothic Arch Greenhouses provide:

Mesh 17 Protection Net

Fewer pesticides are needed to significantly reduce the number of insects entering the greenhouse structure.  Dual protection significantly reduces the number of pests entering the structure, while maintaining adequate airflow and reducing costs.

OptiNet blocks penetration of insects in two ways:

  • Optic protection: Insects are repelled by the screen’s optical additives.
  • Physical protection: The fine 40 or 50 mesh screen provides a second line of protection

Who knew insect screening could provide not only insect resistance; but also shading and some protection from the elements, all while maintaining adequate airflow?  All these features help reduce costs for production in your greenhouse, giving you the most for your greenhouse investment.  Now that you know the details, track down the worst pesky offender in your area, and install some screening in your existing greenhouse, or let us know which mesh is best for your future greenhouse needs!

Grow Organically

In terms of sustainable safe food production, organic matter is a prominent valuable nutrient source for both plants and living organisms. Organic matter is a primary source of carbon (C) which gives energy and nutrients to soil organisms.   

Improvement of soil structure is realized as organic matter causes soil to clump and form soil aggregates contributing to better soil permeability thus improving the soil’s ability to take up and hold water which aids in minimizing soil erosion.          

This organic matter and high carbon content support soil functionality because it improve the activity of microorganisms in the soil and can enhance biodiversity. The primary essential nutrients for optimum production of the vegetable crops are typical, carbon, hydrogen, nitrogen, oxygen, phosphorus, and potassium. Secondary nutrients are those usually needed in moderate amounts compared to the primary essential nutrients. The secondary Nutrients can be divided into two categories: macronutrients and micronutrients. The six elements normally classified as macronutrients are nitrogen (N), phosphorus (P), potassium (K), sulphur (S), calcium (Ca), and magnesium (Mg). The plant roots mainly take up these nutrients in ionic for

In the recent past, progressive farmers have used various natural methods to develop safer means of growing  ‘organic’ certified vegetables using ‘no-till’ crop rotation, inner-planting methods, and cover crops to name just a few. These practices ensure the maximum organic matter remains in the soil resulting in enhanced beneficial microbial and bacterial health of a ‘living’ soil, rather than having a barren dead soil due to chemical fertilizers’ deadly impact on the beneficial microbes and bacterium of living soil.

The Achille’s heal of today’s dependency on petroleum-based fertilizers, herbicides, and pesticides is the vulnerability of the supply chain and the flow of oil.

Best we soon adopt organic agriculture best management practices on a broad basis before conventional chemical fertilizers are so costly that we are forced to pay the price of not being able to produce enough food to feed our ever-expanding population.

Winterizing Your Greenhouse for Heat Retention

Who’s ready for some winter gardening? As cooler temperatures approach, many growers aim to just keep their plants alive through harsher conditions. However, with some careful planning, some energy-saving tactics, and a few products you may already have on hand, you can have a thriving winter greenhouse this year!

Many gardeners are now packing away their shade cloth until warmer weather is near. Letting every last bit of the weakening sunshine into their greenhouse or winter garden is foremost in most growers’ minds, so why keep your shade cloth in place? Depending on what type of shade cloth you have, it can act as a thermal heat curtain in winter. That’s a big plus when it comes to keeping valuable heat inside your growing space!

Aluminet shade cloth is excellent at keeping the heat that your greenhouse has collected from the sun during the daytime inside at night. Hung inside your greenhouse, the aluminum filament preserves heat, and can increase the efficiency of your heater by up to 30%! Many growers will open or remove the shade during sunny days, then close it during the night. This method makes the most of the available sunlight during the day and helps to trap the heat inside when the evening comes.

Aluminet is also successful in reflecting back the invisible heat radiation given off by plants and the greenhouse floor. This heat energy gathers during the day and releases at night in all objects. Traditional black or colored shade cloth can also slow this heat loss but is not as effective as Aluminet in reflecting this heat back to the leaves of the plant.

Shorter days and less light may mean that you want to add supplemental lighting to your greenhouse. If you don’t already have growing lamps, special consideration for winter is heat output. LED lighting, while very cost-effective to operate, can be expensive to invest in and produces very little heat. During winter, metal halide (MH), high-intensity fluorescent (HIF), and high-pressure sodium (HPS) are good choices, due to the heat they produce, as well as the low cost to implement. You can read more about how to choose the best greenhouse lighting here:

Aluminet is also helpful in increasing the benefits of your lighting. The twisted woven strands of Aluminet reflect diffused light back in many directions from the source. This diffusion and reflection promote more vigorous growth in the lower branches, less stress on the leaves, and more even light distribution.

Your supplemental lighting and heating can also be more effectively used in your greenhouse with the addition of a specialized heat-retention curtain. A closed fabric for efficient heat retention, made from woven Polyethylene and Aluminum strips, can be an excellent investment to winterize your greenhouse. In addition to moderating daytime and nighttime temperatures, these curtains reduce shadows, control air movement, and cold spots, and add optimum light diffusion to your indoor crops. Call our experts today for a quote on this new and innovative item!

A natural way to lower your heating costs is by storing heat. Make use of planters filled with soil or even large closed containers of water. Both options store heat, providing you with even more ways to seal in warmer temperatures inside your greenhouse. Moving raised beds inside is a great way to both grow to store your warmth all through the coldest part of the year. It’s a great time to switch to winter-specific crops, which have less sunlight requirement! We have several blogs regarding winter crops, which you can read here:

Now is the time to do yearly maintenance checks on your greenhouse heater. Test your heater and thermostat, and try giving it a test run before you have to rely on it. Perform any needed maintenance and even stock up on key parts that may be needed. As part of your testing, check the accuracy of your thermostat to ensure all systems are functioning properly.

If you’ve not yet chosen a heater for your growing space, you’ll want to consider if electric, natural gas, or propane is the best option for you, as well as if your plants require a vented or non-vented heater option. If you need some guidance on this aspect of winterization, please call our offices! We are happy to help find the best option for your growing situation.

Last, our final winterizing recommendation is to always remember that investments you make today in the future of your garden can have results for many, many growing seasons to come. For some ideas on what to do today to ensure gardening success tomorrow, check out our blog from last year!

Thanks for reading today—we’ve had a long absence from posting, due to the many strains that 2020 and 2021 have brought. We’re pleased to be looking towards the future, and from all of us at Gothic Arch Greenhouses, HAPPY GROWING!

The Importance of Greenhouse Ventilation

A greenhouse’s most important function is to provide the perfect environment for plant growth. Storing the sun’s energy and harnessing it to benefit your crop is the key to all good greenhouse design. Ventilation is essential for balancing an indoor climate that makes the most of the powerful solar spectrum, while keeping an optimal temperature and air quality to help your plants thrive!

Air exchange is important not only for providing the carbon dioxide and fresh air that plants need for photosynthesis. It also helps keep the temperatures inside your greenhouse regulated. In Winter, a greenhouse’s function is to store heat from the sun, creating a warmer temperature in the greenhouse versus outside of it. But in the Summer, an unventilated greenhouse can turn into a furnace, holding withering heat instead of protecting your plants from the elements.

Cooling a greenhouse on a hot day is a difficult task without a good ventilation layout. The most effective greenhouse ventilation system is will use exhaust fans, setup to blow hot, stale air out, and intake shutters mounted opposite, to bring fresh, cooler air in. (Shown in picture)

An exhaust fan system should be able to make a complete change of air in 1 to 3 minutes in summer to keep temperatures in the greenhouse at a reasonable level. One minute or less is best for small greenhouses; Two to three minutes is acceptable for large commercial-sized greenhouses.

Plants require fresh air year-round, which is why it is important to have equipment with options like louvered fans, motorized shutters, and variable speed motors that will help prevent heat loss when it is cold outside.

Roof and side vents are also helpful to supply fresh air to plants and cool your greenhouse. This is also ideal for venting during cold months, because if used with automatic vent openers, fresh air can be supplied to plants gradually, reducing any “temperature shock”. HAF circulation fans are highly recommended for use with side and/or roof mounted vent systems. These fans move air throughout the greenhouse, eliminating hot and cold spots. The increased air movement helps to expel hot air out of the window vents and provides fresh air for plants.

Air movement, cooling, and some additional humidity can be provided by an evaporative cooler. It will provide additional active ventilation, bringing in cooler air and exhausting the hotter air through existing roof vents. Evaporative coolers can be used in conjunction with exhaust shutters like in the diagram below.

A combination of shade, proper ventilation, and an evaporative cooling system, misting system, fogger, or wet wall can be very effecting for regulating high temperatures. A greenhouse allows you considerable control over your growing environment; however, even using all of the items mentioned above, you can expect a greenhouse to still not be much cooler than the outside temperature in extremely hot, humid areas. 

Many plants thrive in warm, humid environments, but this is not the optimal climate for all plants. Researching your particular crops’ needs can help you to find the right combination to keep your plants healthy and happy. The effectiveness of your ventilation, your cooling, your humidity, and your outdoor ambient temperature are all very important factors to keep in mind when choosing your greenhouse crops for mid-summer. For expert advise to guide your greenhouse ventilation plan, give the experts at Gothic Arch Greenhouses a call today. We’ve got the knowledge and experience to help you make the most of your growing space, all year round.

Why is Aluminum the best pool enclosure framing?

1) Steel Rusts…Aluminum Doesn’t

Unlike Steel, which rusts due to the presence of iron in its composition, Aluminum does not rust. When continually exposed to oxygen and water, the surface of steel gradually becomes pale and brown, and it loses its aesthetic value.

Even galvanized steel isn’t completely immune from rusting, as the paint will wear off (especially around the joints) with time due to the effect of weather extremities, thereby only delaying the inevitable. You’ll have no such worries with aluminum.

Aluminum is naturally resistant thanks to the protective layer of aluminum oxide that forms around it when it interacts with oxygen and water. This layer shields the insides while also rendering corrosive elements inert, thereby ensuring the framing retains its visual appeal for years. 

2) Less maintenance

Since it doesn’t splinter, crack, rot, or rust, an aluminum frame requires little to no maintenance work. That saves you both time and money. Steel frames also don’t have too much work save for the periodic painting- particularly necessary in cold climates plagued by snow and ice- which brings labor and material expenses. 

3) Aluminum is lighter

Steel is about two and a half times denser than aluminum, so it makes for a more massive frame that requires some effort to build and repair.  The opposite is the case for the latter, which is light and malleable.

So what will it be?

An aluminum or steel frame, what will it be? Both are solid options and your choice will largely depend on your specific needs and how much you are willing to spend.

Pollinator bees

Everything you ever wanted to know about Pollination, but were afraid to ask

All vegetable crops that produce a fruit need pollination to produce food. In contrast to leafy greens, legumes, roots, and tubers, fruit-bearing plants require pollen to produce an edible crop.

If your vegetables are not yielding fruit, or the flowers are not developing healthy, maturing fruits, it could be due to poor pollination. Some typical causes of poor pollination are late frosts, prolonged rain, unseasonable cold, lack of humidity, or no access to pollinator insects.

Pollination in a greenhouse

When growing inside a greenhouse, the ability to completely control your growing environment is always your greatest asset. When it comes to pollination and growing food crops, there are elements of that environment that need special consideration.

A dry atmosphere can lead to poor pollination, and malformed fruits, berries, and vegetables. Be sure that your indoor environment is humid enough to encourage healthy pollination and growth. For larger greenhouses, a mist irrigation system can be a great solution.

Insects can be scarce in a greenhouse environment. It is easy to forget that insects do the important job of pollination, and if you are rid of them completely, your plants can suffer. One solution is to leave your greenhouse door open on days with favorable weather. Pollinator-friendly companion planting can be done around the perimeter of your greenhouse to encourage the insects you want to visit.

Another solution is to pollinate by hand. Self-pollinating plants (those which have both male and female parts within the same flower), can be gently shaken to loosen pollen and encourage fertilization. A more reliable way to pollinate is by using a soft paint brush to brush the inside of each flower, moving pollen from the stamens to the stigma.

For plants that produce both male and female flowers, pick a male flower, which will have three to five stamens with pollen- producing anthers. Strip back the petal to rub the stamens against the stigma of a female flower. Female flowers have a swollen ovary or fruit at the base of the petals, which male flowers lack.

For some plants, you’ll want to avoid pollination. Vegetables that are produced for their greens, bulbs, or roots, should not flower and seed. Once plants have flowered, they produce fewer leaves and concentrate their energy on seed production. This can make the leaves taste tough and bitter, or reduce the size of the edible root or bulb.

Companion planting for pollination

To encourage pollinator insects to visit your garden, plant flowers nearby to your food crops. or outside of your greenhouse area. Some flowers that encourage a broad range of helpful insects are comfrey, geranium, lupin, cosmos, borage, buddleia, lavender, and sunflower.

Basil, if left to flower, attracts several types of bee and improves the flavor of tomatoes and lettuce. Dill, oregano, sage, and thyme planted throughout the garden and allowed to flower can also brighten the flavor of many vegetables.

Trellis climbers and hanging potted strawberries benefit from hummingbirds. You can attract them with large, colorful flowers such as zinnias.

Calendula grows well with summer squash, and cosmos companion with cucumbers. These attract not only bees but also garden flies. Their larvae are predatory to aphids, leafhoppers, and other garden pests. Stone fruits, grapes, fennel, carrots, and beets are beneficial fly favorites. Plant alyssum, buckwheat, chamomile, and parsley to increase their numbers.

Butterflies love zinnias, batchelors button, coneflowers, daisies, marigolds, and wildflower mixes, but will visit any brightly colored flower they can perch on. They are passive pollinators, transferring pollen as they look for nectar.

Flowers that are open during the night will attract pollinator moths. Try Evening Primrose, Moonflowers, Four O’Clocks and Gourds.

Bats are excellent garden companions!

Bats also enjoy night-blooming flowers. Bats passively pollinate, and will also eat small flying pests, including mosquitoes. If you add a bat house to your garden area, you will likely notice a drop in mosquitoes as soon as a bat takes residence. A single can eat up to 1200 mosquitoes per hour, and will usually dine on 6000 to 8000 insects per night!

For self-pollinating plants, repelling damaging insects can be more important than attracting pollinators. Marigolds are one of the most effective repellents, and can be combined with all of your garden vegetables. Geraniums, lavender, and mint also repel damaging insects.

Advantages of Growing in a Greenhouse

Though we may be a little bit biased, here at Gothic Arch Greenhouses, we believe that growing in a greenhouse is the best way to ensure success, no matter what your gardening or farming goals. Greenhouses can help you get bigger blooms on your prize-winning flowers. You can harvest more fresh veggies year-round. With a greenhouse, you’ll have fewer pests and disease issues. You can even grow plants that wouldn’t thrive under outdoor conditions in your climate.

If you’re considering a greenhouse, or even if you already have a greenhouse but haven’t yet unlocked its full potential, then read on! We’ve compiled the best reasons to grow in a greenhouse, and we’ll even address a few potential drawbacks (though, really, we think the benefits far outweigh them). We hope we’ll have you growing in a greenhouse the second you finish reading!

Extend Your Growing Season

One of the best reasons for growing in a greenhouse is the potential to extend your growing season. The controlled environment inside a greenhouse keeps air and soil temperatures stable, allowing earlier planting and later harvesting. You can also delay planting, or plant to harvest repeatedly, in cycles.

Stable temperatures cause less stress to the plants and promote strong growth throughout the year. With a greenhouse, you are truly in control of your cycles and growing seasons.

Even in an unheated greenhouse, many greens and vegetables will not only survive the cold, but require a cold period for maximum flavor. Some plants started in fall will not grow much, if at all, when it’s cold. For those cold-hardy varieties, they will continue the growth cycle, even in freezing temperatures, and be ready for harvest when the temperatures rise.

Starting seedlings early in a greenhouse to later move to an outdoor bed will give you a great advantage when planning your gardening calendar. A greenhouse gives a great start to your plants at their most vulnerable stage.

Eating from your greenhouse year-round is a great benefit for growers!

Create a Consistent, Protected Environment

Growing in a greenhouse allows you to create a consistent environment for your plants, safe from weather extremes. Excessive rains, withering heat, sudden frosts or temperature drops, drought, and high winds will not affect your crops.

You can get more consistent results from your crops in a consistent environment. You can also grow plants not native to your climate. As long you understand the ideal conditions your crop requires, a greenhouse allows you to adjust your climate to produce a perfect harvest.

Bigger, more rapid blooms or harvests come with the ability to increase the humidity and temperatures to the levels plants love. Not only can you increase surface transpiration rates, but you’ll also conserve water while doing so!

Catch the Sunshine!

Our Gothic Arch Greenhouses motto is, “Catch the Sunshine!” Growing in a greenhouse truly gives you the ability to capture the sun’s energy, heat, and light spectrum. You can diffuse the harsher, withering summer rays effectively, keeping plants healthy while stimulating growth.

A greenhouse gives you the ability to control light with the use of shade and blackout cloths, so you can also control flowering, seeding, and fruiting cycles of your plants. Proper shading can also help avoid heat stress and burns from powerful summer rays.

Capturing solar heat energy rather than using traditional manufactured heaters is a great greenhouse technique. This involves creating thermal solar mass, using natural materials that readily absorb, store, and release thermal heat.

The powerful, full light spectrum of the sun feeds plants during the photosynthesis process. With proper ventilation plus plenty of sunlight and water, plant growth can be dramatically increased in a greenhouse due to diffused full spectrum light reaching the surface of the leaves.

Protection from Pests

Outdoors, crops are often at the mercy of common insects and other pests. Indoors, it is much easier to manage seasonal pests like caterpillars, locusts, mites, and many more.

Predators like moles, deer, rabbits, and birds won’t be able to eat or attack plants growing in a greenhouse. This reduces the need for toxic pesticides or chemicals, and gives you the advantage of being able to keep a close eye on your plants.

Best Use of Growing Space

Greenhouses allow growers to make excellent use of their available growing space. Planning your planting space in a greenhouse gives the advantage of growing tall along sidewalls, and trellising crops easily. You can grow on multiple levels in-ground and with benches and baskets.

Being able to grow out of season plants also makes your greenhouse a year-round rather than only a seasonal growing space. Rather than having a garden plot that lies dormant half the year, your greenhouse can produce throughout the seasons.

When growing in a greenhouse, you have the added benefit of variety. You can plant anything that you like in it! From vegetables & fruits to flowers & herbs, even cactus and bonsai can grow in harmony. Without planting directly onto your garden soil, many varieties can co-exist easily.

Disadvantages of Growing in a Greenhouse

There are some possible “cons” in a list of many “pros” when deciding on a greenhouse purchase. We’ll discuss a few of those now.

Upfront Cost of a Greenhouse

The primary disadvantage for many people looking into a greenhouse for the first time is upfront cost. A solid, well-built structure that will stand the test of time is an investment, and operating costs for heating, cooling, and air circulation can seem daunting.

The good news is that Gothic Arch Greenhouses has financing options for qualified commercial growers and residential growers alike. A greenhouse can increase your long-term property value, and in the short term can save you money, by supplementing your food stores and reducing your grocery bill, and by saving money on spring plants and decorative landscape items.

Tough economic conditions cause higher costs for vegetables, flowers and fruits. Growing in a greenhouse can provide you and your family with a consistent supply, year round. Many growers recoup their costs on a greenhouse with the savings from planting their own crops within one year or two.

Lack of Know-how

Another consideration is that you may feel you don’t have the know-how to get started with growing in a greenhouse. The cost involved may cause you to feel that it is not justified for a “hobby” level grower to build something substantial and permanent, or you may be a long-time outdoor commercial grower who is not comfortable moving into a more technical growing set up.

A wonderful thing about the gardening and growing community is the willingness to share their knowledge. Modern greenhouses have been in use for hundreds of years, and the wealth of information for tackling most any type of problem is astounding!

How to handle whiteflies, identifying disease early, planning for a particularly harsh winter– these are questions every gardener faces. Proper air exchange for best plant growth, when and how to add supplemental lighting, and when to add nutrients are similar challenges that are more specific to growing indoors, but all of these are topics which have great solutions online and in gardening publications. You can get more precise advice by calling your local agricultural extension office or your greenhouse supplier. We here at Gothic Arch Greenhouses are always happy to help.

Get Growing in a Greenhouse!

As news of supply chain challenges, farm labor difficulties, and unusual patterns of fresh produce demand have become part of our daily lives, greenhouse growing is getting more and more consideration. From farmers who want the ability to automate their harvest to homesteaders wanting to decrease their dependence on grocery stocks, a greenhouse can help keep a steady supply of healthy nutrients ready for harvest year-round.

Happy Growing!

Greenhouse Growing Saves Water

With the economy on everyone’s minds, finding ways to cut expenses as well as converse precious resources is good for both the earth and for your bottom line. Water is vital to plant growth, but in many areas can be in short supply and high in cost.

Greenhouse growers use as much as 61% less water than outdoor farmers. This is due to reduced evapotranspiration rates, drip and flood irrigation methods, closer crop spacing, and shorter crop cycles. Growers also cite sustainability, more frequent harvests, ease of pest control, and more control over their growing environment as additional reasons they are choosing to move crops traditionally grown outdoors in. Water-borne disease is also easily reduced.

Just within the United States, 38 percent of our fresh water consumption used for crop irrigation. Worldwide, 80 percent of our fresh water supply goes to crops. Irresponsible watering practices can create a huge strain on water supplies, can contribute to disease, and can affect the quality of the water supply.

Growers with an eye towards the future are more and more turning to greenhouses to protect their crops, protect our natural resources, and protect future generations’ world. As many areas face water shortages, decreasing water loss when tending for crops is vitally important.

A recent study of tomato growers showed, pound for pound of yield, greenhouse producers used approximately 61% less water than an open-air farm. Additionally, frequently cycling crops gives more harvests, while having fewer heavy-watering days within each cycle.

Within the greenhouse, water quality can be managed with ultraviolet light purification, which reduces instance of disease and pathogens. Water filtration can also help growers in areas where groundwater has increased salt intrusion or heavy mineralization.

Quick Growing Fruits and Vegetables

Waiting for a garden crop to produce its first edible reward can seem to take an eternity. If your aim is a quick harvest, consider growing these fruits and veggies. You’ll have a bounty in no time flat!


Microgreens can go from seed to harvest within 2 to 4 weeks. Microgreens are young and nutritious vegetable and herb plants, packed with vitamins and flavor.

Popular microgreens include radish, chard, kale, endive, mizuna, basil, amaranth and cilantro but you can use anything that has edible leaves and stems.

They are best grown in shallow trays or containers, making them a great choice for people with limited space.


Sprouts, similar to microgreens, grow quickly in a sunny spot with a shallow container and plenty of moisture.

Beans, broccoli, alfalfa, lentils, and even almonds can be sprouted, and are packed with vitamins and minerals. They produce quickly, and can add punch to your salads and sandwiches.


Radishes are one of the fastest growing plants you can grow.

They go from seed to harvest in just 22 in most climates, though some varieties can take up to 50 days.

They are easy to grow, and add a kick of peppery flavor to your fresh salads and sides.

Green onions

Delicious green onion stalks can be harvested just 3 or 4 weeks after planting. After planting onions as bulbs, in around 6 months they will produce full-size onions.


Leaf lettuces such as Romaine or Cos can begin to be harvested in as little as 30 days after planting.

Pick lettuce leaves when the leaves reach at least 3 inches, rather than harvesting the entire head.

Other lettuce varieties mature in 45 to 60 days.


Delicious, tender baby carrots can be harvested after about 30 days. Other carrot varieties take between 50 and 80 days to mature


Spinach is easy to grow and requires little care aside from watering. It is versatile and is ready in as little as 4 to 6 weeks after planting.


Cucumbers are delicious fresh or prepared, in salads, on sandwiches, and pickled.

Cucumbers vine and run, so trellising with plenty of space to grow is the best way to raise them.

Baby cucumbers for pickling can be harvested as early as 50 days after planting. Well-cared for cucumber vines will produce again and again throughout the season.

Leafy Greens

Kale, mustard greens and watercress are super healthy greens that are fast growers. Most take about 50 to 65 days to mature, but baby leaves can be picked as early as 25 days.

Arugula can be grown annually in nearly all zones and can be harvested after 30 days.

Bok Choy grows well in moderate climates, and the individual leaves can be harvested after 21 days. The whole head is mature in 45 to 60 days after planting.


Snow peas take only about 10 days to germinate and are ready for harvest in about 60 days. Plant more than you think you will need, though– they can be tricky!

Bush beans

Most varieties of bush beans are ready to harvest within 40 to 65 days from planting.

Summer Squash

Yellow summer squash can be ready in as few as 35 days from planting.

Many varieties of squash, including zucchini, are ready in 60 to 70 days.

For best flavor, harvest squash when they are still small. They will reproduce so quickly that you should have daily harvests all season long.


Broccoli is a hearty veggie, and can withstand a dip in temperatures better than most in the garden.

It is a good choice for very early season planting.

It can generally be harvested in 7 weeks time.

Ever-bearing strawberries

This variety of strawberries will fruit well in containers or hanging baskets. They produce several medium harvests over the course of the season, the first in roughly 50 days.

Strawberries will produce runners, which look nice when cascading down the side of a pot, but take energy away from the plant, reducing yield.

Snip runners with sharp hand pruners as they appear to encourage maximum fruit production.

Raspberries and blackberries

Cane fruits like raspberries and blackberries have a tendency to take over the garden with their aggressive growth.

New compact cultivars, like Raspberry Shortcake raspberries and Baby Cakes blackberries, have changed that.

They reach a maximum height of roughly 3 feet, and have thornless canes. They will produce in approximately 50 days.

Encouraging faster growth

To see results even faster, the controlled environment of a greenhouse can do wonders to your food production. Supplementing light, keeping weeds from stealing valuable nutrients, controlling pests, and having optimum conditions night and day helps plants to reach their full potential quicker.

Grow Your Own Sense of Food Security

Food Security

Amid the global crisis of staying healthy as a pandemic threatens our daily lives, food security is more on our minds than ever. Having access to your own supply of fresh, nutritious food when stores and supply chains are unreliable can give you peace of mind, as well as a healthy diet.

This year, we began a blog series to promote year-round growing, not knowing what would lie ahead. Many of our recommendations have given advice on how to grow food not just in a large garden or greenhouse, but also utilizing containers indoors, balconies, raised beds– really anywhere you can add a little green to your life. Now, with quarantines and supply chain disruptions, we understand that growing food for yourself may soon be more than a hobby, and might impact your overall food security. With that in mind, please enjoy our top recommendations for quick starting your food production and getting your plants to start producing ASAP.

How to Stimulate Quick Plant Growth


Like all living things, plants will thrive in an environment that is suited to their needs. Nourishment, light, water, and optimal temperatures are needed for seedlings to develop into healthy, bountiful crops. The absence of any one of these components can disrupt the plant’s ability to grow. Practicing good gardening methods and creating the healthiest environment for your plants will result in hearty yields and increase your own food production.

Soil for quick plant growth

Soil is the best place to start when planning your planting. Different plants have different soil requirements, so plan your in-ground bed arrangements to be able to separate your soil additives. If you are growing in containers or in a greenhouse, this becomes much easier to plan.

Start with a soil testing kit to determine what your soil is composed of, and what it may lack. Nitrogen, phosphorus and potassium, organic matter, and other soil additives can enrich your plant’s soil and nutrient profile.

Your seedlings may prefer rocky or sandy soil, or richer, more dense soil, so be sure to check a Farmer’s Almanac or other sources for your specific plants’ needs. Your local Ag. Extension Service an excellent resource to assist in your gardening endeavors.

Lighting for quick plant growth

A plant’s primary food source is light. Whether natural or artificial, without adequate light, plant growth can be stunted and slow, due to limited photosynthesis. Plants use all spectrums of light to create sugars for their survival, as well as to trigger growth responses.

A greenhouse is the best way to capture the sun’s power, promoting growth while keeping your plants protected from pests and adverse conditions. Greenhouses can also be outfitted with supplemental grow lights, or with blackout tarps and covers, both of which can be used to affect plants blooming, flowering, and fruiting cycles.

When growing outdoors or inside your home, planting on a south-facing slope, or in a southern exposed window where the sunlight pours in will generally speed up growth and fruiting. In any growing environment, if you can give extended light periods (in your greenhouse or under lamps) that will boost production immensely and reduce both weed and pest invasion.

As with soil, different plants also have different lighting requirements, so check online for the best advice for each crop you are growing. Researcher partners from the John Innes Centre, the University of Queensland, and the University of Sydney found that using lights that are optimized for increased photosynthesis in specific plants increased crop production threefold.

Temperature for quick plant growth

Maintaining the perfect temperature for your plants can be difficult. Making use of hoop houses, covering when there is a cold snap, and adjusting watering schedules can help, but more perfect control can be obtained within a greenhouse setting. Maintaining the correct temperature for specific plants encourages growth and prevents damage. Know which temperatures your plants thrive in to encourage faster and healthier growth, and plan your planting calendar to take the best advantage of natural weather patterns if you are not growing inside of a greenhouse.

Increasing Food Security in Your Community

An idea that is taking hold in many communities is cooperative growing. Friends and family plan their crops together to take the best advantage of their own resources and can grow a greater variety of foods to share together. If you have a greenhouse full of juicy tomatoes, but your neighbor’s sandy soil is more suited to cilantro and root vegetables, then cooperative growing might be a great solution to increase your food security.

Staggering plantings and harvests with friends and neighbors will also help decrease your labor. If you plant two crops with similar light, soil, nutrient, and watering needs, and your co-op partner plants two different crops, then you can both optimize your feeding and watering efforts yet still have a variety of fresh, healthy food sources.
