:smoking: Cheers Nate, thank you.... I'll be giving it some serious thought, gotta do my savvy consumer homework first though!
I have a 4x2x5'h, which can only be run part of the year in a small outside courtyard starting around May... I run smaller pot volumes to allow for more cultivar variety, 3-4 plants max. This tends to end up with plants at variable heights and finish times, so I need multiple lights to allow for height adjustments and angling if needed. I have 2 AutoCOB's, which I plan to use for perimeters because of their very compact size, but the old 2-COB conversion a friend made for me a few years ago from the body of a Platinum rip-off brand is a noisome clunker. I want a Q-b to occupy center stage instead-
You're in fine hands with Bushy, so no worries there! LED's are fantastic of course, but folks new to them coming from HID or especially fluoro's have some learning curve to navigate... Often I find folks underestimate LED's actual "potency", erroneously using their eyes or other lighting as a comparative gauge which we know is bad news for anything PAR/PPFD related with LED in particular. Also, since heat is not an issue, symptoms of non-burn light stress are less obvious and often are mistaken as something else... Staff all harp on about following light distance recommendations because of this!
Something else I've been wondering about is the apparent elevated demand for Ca in LED's, given the frequency of grow showing defc. symptoms, not all of which can be accounted for by nutrition and other factors... I could be mistaken, but early gen' LED blurples, this seemed to be more common; with more and more full spectrum "white" lights, it doesn't seem to be as prevalent..? I don't know, but it sure begs the question if this is the case, or if it's because early on growers were just not used to working with LED and overblasting their plants... What's your take on this?
