That's cool, man. Thanks for sharing that.I just use agros pure UV t5 vertically 3ft away 15mins x3 daily, I just prefer the way my plants taste/smell with the added A/B, visually I've never noticed more trichomes just more color in the trichomes which i also prefer.
I honestly cant imagine using a stronger bulb than this, if anything a weaker bulb is easier to work with if you can mount it at the same height as your lights instead of above or at the side.
I'd like to find something to run at same height as main light - as you say. So if that's quantum boards, I guess some UV that can be used at about 18" to 30"...? Hah, pretty big range. Sometimes QBs can be as close as 16" (closer for some/some setups).
It's looking like Arcadia then I think.
