LMAO, so a friend of mines sister got a new tanning bed for Christmas. She gave him her old one for moving the old one out and installing the new one. Anyway, he ask me this same question, and I gave him the same answers I found in this thread
Massive power use- Its got its own special 220V 20amp circuit, and the timer which only goes up to 30min will have to be by-passed
Wrong spectrum- Likely to cook any plant even from 5ft away
Old bulbs- If I'm not mistaken the bulbs need to be changed out every couple years
Im going to check out his grow tomorrow. He currently has 2 super lemon haze and 2 white widow clones under it.
I think his best bet is to strip the ballast, tombstones, fans and reflectors out of the bed; go get some 4ft T12 HO grow lights, and build a good closet.
I'll keep you guys updated, this will be interesting
