Can anyone give me the heights for different grow stages? I have the specks, but no info on growing. I am having trouble finding info, even from the place I bought it from. Is Wilee Peyote still around? It's been a while, I'm ready to use my new light in my 4x4 tent, but it came with NO paperwork. I have recently grown with my Spider Farmer LED light, completely different than these powerful COBs. Any info will greatly be appreciated. I purchased it from All GREEN Hydroponics. Thanks
