Guys I moved my light closer(150w hps) BC its getting cold and I'm not sure how close it should be any way no signs of heat stress as of now although I just did it. As of right now its sits exactly 8 3/4 inches from the tallest point on the plant I have plenty of fresh air rolling through and temps are dropping below 50 every night outside and some parts of the house (which is when I run my lights) and sticks around 77-80 around the tops of the plants.
