Ive seen this question pop up several times about blacklights and growing. Ive read that blacklights do not grow weed due to the fact of the high UV it puts out. However, Ive been growing a plant under a blacklight and it seems health and fine so far ill put a pic below. However, ive researched and heard different things such as mixing in a black light will triple the THC in a plant (complete bs it sounds) also that it will work all the way up to the budding stage of the plant? If someone could come in and clarify what is true and what isnt would probably be great for others asking the question along with myself. however my plant has been looking perfectly fine as if I grew them under CFLs heres a pic:
1 week and 3 days into it:
the specs of stuff on em are water my phone doesnt take great pics
any comments on this or will they actually grow that far with a BL and then die soon?

Black light for growing weed
the 2 kinds of black lights make UVA light, one type creats a “little” blue light, but not much. and it uses filtered glass.
UV damages plant cells. whether or not uv causes the plant to create trichomes, i am not sure.
which is why i say they may help thc, but they dont help plant growth!
this is probably why many plants have anthocyanin, to protect against UV stress on the cells.
form my understanding, UV doesn’t really do jack shit, it stresses the cells and causes certain pigments to be there to avoid stress (among other things like too much light).
in a way it may be good for bud, cause it *may* increase tch production which may be a secondary defense against harmful radiation. but as far as a growing plant, it just wastes a plants energy while growing.
I have 2 inexperienced buddy’s who both grow under black lights and their plants have turned purple does anyone know anything about growing with black lights is their anyone else who has tried this
