may i ask why your running tests using arcadia bulbs... made for reptiles.
why not run tests using bulbs made for cannabis like migro uvb 310?
i would love to believe what you are saying because i can get UVA lights near me super cheap! and for me too add a UVB light into the mix i would need a new led light a new uv light + fixture etc. its 5x cheaper for me too roll UVA but im super scared that my end quality will suffer because of no UVB

.
in the past when me and my bro would grow fire we would always use solis tek 10k metal halides which had UVA/UVB/UVC and our end quality would skyrocket!
i guess i can grow using only UVA this grow and see what results i get

im so scared lol.
thank you btw for the testing you have done so far i appreciate you
