Jan 17, 2017 Thread starter #3 M MuchGrow 420 Member I put it 10 inch away now. What do you think is the proper distance when using 250w? Thank you for your comment anyway, confirms my thinking.

Jan 17, 2017 #4 fanleaf Well-Known Member Heat stress big time. If your grow room is 32c or 88f your tops are probably about 100f or 50c. Environment is the biggest key to growing decent plants and you knnow none of the important details so it's a guessing game. Yours is too hot though.
