Do you have any ventilation for that box?? Do you know what kind of temps you have inside there?...and the Aluminum foil isn't a good idea, you can create hotspot's and fry those little guys even with CFL's. You have a lotta Lumens on those little guy's, maybe unscrew a few of those lamps for now too.
You might want to buy a cheap "space blanket" and use that as a reflector. Maybe a CPU fan for the box as well.
Just my .02
OMB Reviewed by OMB on . New Setup Hey guys. Just startin a new grow last ones didnt do to well. I made the mistake of using a hooded lamp system for my cfl's. This time i went out got a storage container and tried over. More light and the ones ive started look happy. Tell me what you think about the setup this is my second attempt hopefully we have sucess. Im using 4 6500k 26watt cfl's and two 2700k 26 watt cfl's for both ends of the spectrum. Tell me what you think and i'll keep you guys informed. Rating: 5
