How close do I go?

[Tahiti Allen]

Hello Everyone!! I've got 5 plants, about 5 inches tall and I've got 4, t5's, full spectrum, 5100 lumens ( a piece ) and I got the lights about 2 inches above them! I want to add more T5's, I know this will increace my heat index, my question is, how close or how far do I put my lights,! I know, the closer the best but with 6 T5's, the heat index will be too high if they are too close! How close should I go?!:hubba:

any flo you can get as close as 3" off the tops and then if its too hot for the back of your hand at the plant top then raise it by 2" and go again and that wont be too hot for them
