vegging with MH is best...but, too far away is better than too close.
UV rays are strong with MH light. If you want to know how strong?...stick your hand under it for 5 minutes...
... & wait for the pain in two days....just kidding...don't do that!

If you burn the tops...it takes a long time to recover & not all reflectors are created equal.
