In my opinion, it may be a little much for brand new seedlings to have it so close - I move my light about 3 or 4 feet away from brand new ones for a few days and gradually get closer after that. You might want to get a couple of CFL while you're at HD...few days under CFLs (close - inches from seedlings) and they'll be much more prepared for the intensity and heat of the 400w.

Good luck & happy growing
doco Reviewed by doco on . light finally came and first grow is underway inside my closet only 1 seed has sprouted out of 4 so i stuck it under the light i was wondering if it was ok for them to be on the carpet..? tommarow im going to home depot and getting 2 pieces of plywood and make 2 walls, both pieces nailed at 90 degrees with some kind of reflective material on the walls and the closet walls.. should have the 3 other seeds sprouting soon and was wondering if the 400w hps was too much light and heat for the little plants.. hopefully the picture works Rating: 5
