150hps klight

Howdy all i got a small room with 1-3 plants at a time my question is how close do i keep my 150hps lights to the tops of my plants thanks.

ok a few ppl have viewed this but no replies um how close can i keep my 150watt HPS light from the tops of my plants i got them about 14 inches now i want to get max light output but not so close i burn them how close do i keep them?

Keep the light as close as possible without burning. A good rule of thumb is like smalltimetoker said, stick your hand under the light, if it's too hot for you, it's too hot for you're little girl. Type in a search using 150 watt, check out the internet search engines if nothing on here. I used CFL's on my 2 grow (this one is very succesfull). I hope that helps.
