heat stress/burn....need help

i'm growina small area about 2f x 5f ...and i have 2 sets of lights 1 in the middle(3x 23w cool white 1x 14 warm) and 1 on top(2x 100w cool white 2x 100 warm white) ...coz i'm using cfl lights so the more the better right
plus i got a small fan(alot larger thna pc fan) and 1 Exhaust fan

1 plant reached the first set of lights and growing above it..so the leafs close to the light got burned

i cant move the lights
i cant move the plant

any idea wat cani do..how can i cool it off?

cut a hole in the box and let the ass of it down for more space..

what is the plan for flowering??

there is still space above about 2f ,,and i tipped the plant...but the lights on the sides is the issue here..

heres a dmnstration

can u take the lights out from the side and attatch them to board and hang over plants... you will have to do so for flowering anyway?

i could but would it be an issue if i just kept it there??

well it would b a issue if it was burning your plants.. and they will bush out more as they get older..

but its your decision..
