I grabbed one of these to augment my 450w LED. Kind of interesting being able to modulate the K ratings. I thought it would be nice for seedlings and then change it up as things progress. Trouble is I don't know how close to put it. I initially was thinking CFL close but then I woke up. Now I'm not sure. Any wild ass guesses are welcome!
