2. Moisture- Make sure your growing trays are either deep, bottom watered, equipped with some sort of drip irrigation, or make sure you’re watering at least twice a day. With temps rising quickly, it’s easy for the trays to dry out.
3. Shade Cloth or Cover- this is important if you started your seeds indoors and move them into the greenhouse. They need to be under some filter or protection from the sun so they have time to develop the photo receptors needed to process the intense sunlight.
