Hi everyone,
I have 2 northern lights autos (seedlings) in a 90x60x90cm grow tent with 2ft 4-way T5s at 96w. I read that T5s hardly chuck out any heat and can be placed literally centimetres above plants, so I figured they would be perfect for my relatively small grow space. I've found however that they heat up a lot, and therefore my whole tent gets too hot and my poor seedlings are suffering for it. The lights are currently a good 12" or more above them so I wouldn't dare put them only a couple of inches above them or they'd burn to a crisp!
Could my lights be faulty or is this normal? Perhaps I would be better off buying a 125w CFL w/reflector or would that get just as hot? My only 'ventilation' is opening the vent flap and a desk fan in the tent that is blowing the hot air under the lights away from the plants, but I think the overall temp in there is still too hot for them.
