I have been reading a lot of web sites, solacure, black dog etc.. I now have a headache,,, everyone's light is the best according to them, and not all agree on what spectrum is the best. Some say UVA is all thats needed and UVB only damages the plants, while others say UVA does nothing, it's the UVB thats needed because of the damage. Some say THC and CBD are increased while others say only THC is significantly effected, and CBD may actually drop.
Makes my dyslexic a$$ very confused, just who does one believe? Certainly not any add!
And the tubes only last 2 grows, really only 2 grow cycles?, before they need replaced because they have lost nearly all their efficiency. LEDs I have seen to this point have a 5 year warranty, which says to me the LED is going to be more reliable in the long run, but also more cost up front. (at least in pre-built units)
They also say the hours of operation depend on how close or far from your plants they are, the further from the plants the longer the cycle can be.
Edit; I have always used mirror panels to reflect the light around any inside grows I have done in the past. After reading a lot of info, I will now be putting in polished aluminum panels as these will reflect the UV spectrum. I have the panels, but they are not yet polished,,,,
