I would wait until the outside temps drop before covering, so choose a time in the evening when you know that it is significantly cooler- such as 830 pm- and leave it on for the next 12 hours. Stick with that schedule. Also, you can help reduce humidity under there by laying plastic over the ground so that moisture in the soil cannot get into the hut.

My question has to do with the fact that there is next to no ventilation within this structure when the plastic is on. The plastic sweats due to the plant transpiration, and it essentially rains inside the thing at "night". The only way i can think Rating: 5
