hi i have 1 week old seedlings and had them 24/7 but changed my mind as they look better after a rest..so going into 20/4 or 18/6....anyway the problem is they been switched on and off a couple ov times inlast 24 hours due to being in bedroom first time for about 8 hours and then like an hour? ohh they under a 400w duel spec in a wardrobe
thanx in advance for any replys

how close are the lights to your plants??? sounds like they could have been too close and were burning them, is it a cooltube??

400w is a bit hot for seedlings. Try using some CFL's for the first 1-2 weeks OR get a cooltuber OR place a piece of glass between the HPS and the plants and have a fan blow on the glass to keep it rather cool( this is a cheaper, not that efficient, but still better than nothing alternative to a cooltube- i have a round piece of glass between my HPS and my little ones. it keeps them happy )

You should get yourself a timer. but no outside you get inconsistent amounts of sun (some days are cloudy some clear)

with your lamp 2 and a half feet away, and fans on it i dont see heat being the problem
