Whether you live in a harsh climate or simply want to grow a delicate crop, you'll need a protective greenhouse to provide a suitable environment for your production. But adding a greenhouse or grow tent alone won't necessarily boost your supply. There are a few things every greenhouse owner should do to ensure proper growth environment and maximize yields.
Control the Climate
Covering your plants to protect them from the elements is just the first step in the growing process. Even on the coldest days, direct sunlight on the surface of your greenhouse can create a hazardous environment. Use vents, fans, or even a climate control system to ensure proper temperatures depending on the species' ideal requirements.
Too Much Humidity Isn't a Good Thing
If you're already in a humid climate, you'll need to take measures to keep relative humidity between 70-85% inside your greenhouse. High humidity reduces growth effectiveness, causes early bolting, and encourages the introduction of fungal diseases. Venting frequently and reducing the amount of watering is a good way to keep your greenhouse from feeling like a rainforest. If you're in an arid environment, you can boost humidity levels by regularly spraying water onto the floor of the greenhouse.
Choose the Soil Carefully
Large-scale greenhouse productions often implement their system with the soil right beneath the structures, but small operations tend to use benches and individual pots for their plants. Whichever direction you take, make sure your plants are getting the right soil. For pots or containers, the soil should be a little lighter and more fertile than ground or garden soils. Organic potting mixes or homemade potting soil and test the pH levels for the proper acidity before potting.
