HI Guys/Gals, anyone got any information on using these new (well new in UK) led panels? whats the light?lumin values? just how many plants can you get under 1 panel? what sort of sucess or failure have you all had with these things? I am thinking of upgrading my grow from 5 to 40 plants and electricity useage/heat is a big issue and these look like to be the cure for both those problems but I can find on definitive informatin about them so any help would be very welcome. Many thanks, Tazman remember if your driving try to keep the car shinny side up!
