yes I close it almost all the way at night to make as dark as hell.

but when the lights R on it stays open. and that helps keep the plants cool when the fan is blowing out and on that big light also keeps that cool.

I'll take a look at the link and see if my problem is in there but I think it might not be. but I'll look anyway.
hydrocannabis Reviewed by hydrocannabis on . plant problem. need some help. so my plant is around 3 weeks into flowering. the problem is that she isn't flowering that good. she IS flowering but really really really slow. what is making her flower so slow. she gets fed bloom ferts only on every OTHER watering. and no light leaks in the dark time. and at 3 weeks flowering her buds should be bigger than they are.
