I was just gonna come ask everyone their thoughts on this......some LEDs, as powerful as they may be overall, only have like trace/residual UV........from what I got speaking with a tech guy at the lighting company, it's because UV lights just don't last as many hours, so there could be issues having to manually swap them out more often.......Ok so I have a bunch of quantum board style LEDs now with Samsung LM301Bs and a scattering of red and IR. Is it worth the money and hassle to add UV. I was leaning towards agromax pure UV based on research.
I’m all LEDs now. My HPS grows did seem to have bigger calyx and trichs but o also changed other variables. So to all the LED only growers using these full spectrum (3000K and 5000K) Samsung diodes, is it worth it???
Ok, so we add UV.......do we need it? Does it increase resin/THC production? Most people seem to think yes it does.....we use sunscreen to protect us from UV, our favorite plants pump out resin.....
Ok.....UV A? B? Both? B Is more harmful but is adding both overkill? B burns out real fast. Is just adding ANY extra UV good enough? I have no problem adding both, the cost for the results is either worth it or barely adding any cost per final ounce.....plus it's fun to go for it......but definitely get good protective glasses, turn them off before working in there......
When to add them? The last 4 weeks of flowering? Ease it in slowly from the beginning? An hour a day? 6? Build....?
