Question for you guys. I have recently purchased a 250 watt HPS setup and was wondering how far i should place the light from my seedlings. As it stands right now its about 3-4 feet away. Is that a good enough distance or do i need to move it further away?
hmm - 250... as long as the air in your growspace isnt entirely still, you could maybe move the light closer... I'd try 2 feet or 2 and a half, and if theres any stretching going on, move it down another 6 inches.
IMO if you can controll the heat ..................ideal distance is 6in check this...http://FunkNugz.overgrow.com/view/HPS-Light-chart--3.jpg;) sorry that was supposed to be a lighting chart...
