When choosing instruments for your greenhouse, consider the following

  • The moisture level in your greenhouse
  • The climate in your area
  • The environmental requirements of your plants


Overwatering is one of the most common mistakes that gardeners make. Using a moisture meter will help take the guesswork of watering by measuring moisture at the root level. This makes it very easy to regulate your watering and keep your plants healthy.

pH Levels

Plants need the correct pH (acidity/alkalinity) level that controls how well plants utilize the nutrients available in your soil. Different plants have different pH preferences. pH testers and kits let you quickly test your soil to determine its exact condition so that you can fertilize and/or adjust pH for best growing results.


A nutrient monitoring systems allow you to quickly and accurately get the nutritional information you need for optimal plant growth. Too little or too much of any nutrient can be detrimental to your plants. These systems assist growers in achieving maximum results from their growing efforts.


Light meters make it easy to measure how much sunlight or grow light your plants are receiving throughout the day. With these meters, you can move your plants around to provide more or less light depending on your plants' needs. Having optimal lighting conditions helps all plants grow and thrive.

Environmental consistency in your greenhouse has never been easier to maintain. To determine which instruments will help your plants grow to their full potential, call one of our greenhouse experts today at 1-800-531-4769.
