I like to keep a MH or HPS light a bit farther away than just the "hand-test" during the first few weeks of veg in order to not burn out the little girls. Well, I think it works better anyway, but I have no real proof.i would say 6" to 8" away you just dnt want the radiant heat to burn your plants if you can get a close as possible would be best jus do the hand test 9put your hand under the light and if it burns your hand or to you seem too hot then its to close)
it is cool to see the growth day to day. they shoot up like weeds!Well only 2 days after my last update she has grown quite a bit of new growth. Check it out. How big should I grow her before taking cuttings for flower?
