I had my plants under 5 two foot T5's and that was my little setup. Veg and bloom under same lights untill i decided to use my closet. Now i have a 400w and a 250w bulb under a reflector i fixed up to take both bulbs. The closet is very warm and all the hairs were white now they are mostly all brown. They were 5 weeks into bud when they got moved into the closet and within a day the hairs darkened up. I realized it was the heat that did it, the lights were about a foot away so now the question is can they even darken the gland heads. About 6 1/2 weeks into flowering now and i noticed a bunch of darkened glands and i'm wondering if the heat from the lights did it or could have burnt them. I got 2 fans in there with the closet door a bit open for ventillation at the moment.
