Its had a lack of air.

Okay, a friend of mine just made a couple of clones. He puts it into closet under 125 blue flourascent(or however it spell) closes the door aswell... the closet is pretty small, so 6 hours later after he opens the closet clones lay leaves touching the surface.. is it serious? My guess is that it has had run out of fresh air all the sudden, because the temperature was above 28 and the air got probably burned or something like that? Will a fan with fresh air be any of help or are the clones ruined?
Thanks alot.

It does sound like heat stress, I doubt your plants suffocated.

How close to the plants was the light? This could be the problem, might have happened even out of the closet. Put your hand between the plant and the light, back of hand facing light. Move your light far enough away to have the plant cool.

Are the stems wilted?

Spray the plants with clean water - dechlorinated, no nutes. Add a fan in the closet, always vent the heat if the door is shut.

I've had heat stress vegging plants before, usually you'll get a level of burnt leaves and new growth above.

If you repost this in Marijuana Plant Problems you'll get more help. Do a search there for heat stress.
