A little light leakage at night time is not going to harm a grow think of the moon lite??? Humidity definitely will...
TheChameleon Reviewed by TheChameleon on . Humidity at night Help As of right now i've got a tent grow with ventilation and everything and i'm on my 12/12. During the light time the humidty is constant around 45-50% humidity. At night I turn everything off (including exhaust fan) and patch up the vent holes so no light can come in. the problem with this is at night the humidity in the tent is reaching up to 70% which i'm assuming can be bad and cause mold. should i be keeping my exhaust fan on all night as well? only problem with that is in the morning Rating: 5
