I grow a tall sativa in a seven foot diameter grow area. This allows the Arcadia to be set back the 18" necessary to dilute the UVB.
View attachment 2054967 My testing on single plants at 122 micro watts showed 20% stunting. I put in an LED system and I got the 20% back, science kicks ass. This bud is 29" from a single Arcadia, damn.
Any amount over 75 uw caused creeper weed in my sativa AND my indica, and the more the merrier. Although the stunting is in direct proportion as well. I took UVB levels all the way to 2200 uw in testing, levels over 1100 uw totally destroyed the plants, 850 uw caused over 50% stunting. I shoot for the 100-200 range.
Shorter plants are kept closer to the Reptisun's, 130 uw on the lower buds at 16".
I harvested three plants that had spent their final four weeks in this room (new room) and the improvement over the non UV supplemented buds is enormous, several visitors showed up to help with the testing, we are unanimous. The bud in the picture is still a week or so out.
