I've been using the UFO LED light with red, blue and orange at 12". White Widow clones are vibrant and nodes are very close and bushy with no stretching. Using SuperThrive, hydrogen peroxide and VF-11 liquid fert in my RaftRooter for my diesel cuttings .
I am using a UFO LED grow light with Red, Blue and Orange lights. I have a 2 sliding door closet set up witj 3 white widow clones and a RaftRooter with cuttings off a diesel plant. The light is about 12" away with NO heat from the lamp. 18 hrs for now.
Just installed UFO TriBand LED ($240 on E-Bay) in closet over 3 White Widows in gallon soil pots and 4 Diesel cuttings in RaftRooter hydroponic tub. Any ideas how high the light should be (at 12" now) and how many hours of light (20 hours now). Ist time inside to start. Was buying 2 ft tall...
