Ayo @Spider Farmer, why do your UV bars only cover 365-420nm? We need 285 nm coverage for UVR8 stimulation. This is a puzzling development, as I was about to switch from my old UV source as my tubes are flagging… when I noticed the spectral data.
Any chance of getting a Canadian UL-listed bar with proper UV and some juicy Far Red(700-750nm) modes?
Research has shown that adding FR increases leaf area, and dry root/shoot weight in lettuce by quite a lot.
