In previous years we always covered in the evening till it got dark and uncovered when it got dark. It is not completely dark at all at nighttime there are a few street lights in the distance and a neighbors censored light that goes off here and there. My question is would it be better off tarping/covering around 7pm and uncover 7am? We also only have so much power when covered we can run fans or a dehumidifier at once, my buddy was telling me i wont have to run the dehumidifier till the buds starts bulking up, its a solexx greenhouse. Thanks
