[QUOTE=turtle420]The hand test...

I think a good test is the hand test...

Place your hand under the light, and move it closer until it starts burning... then place your plants just a little bit lower.

You should have air circulation over your 'canopy' and/or over your plants. You might consider a sealed reflector housing... or a cool tube.

Thanks. Unfourtunately, its a wardrobe stealth grow, so cant make many changes to wardrobe, except get a small fan.

and hope for the best
