For the UV part of the light to promote resin production, it should be UVB light at roughly 310nm. I believe that SpiderFarmer UV/IR supplemental light is providing UVA at 380nm and above. Is the light capable of running UV and IR at separate timing?
I have 2 sets of Grower's Choice UV/IR addon bars on my two ROI-E720's. I want to use UVB lighting because I've heard some good things about it. Does anyone know what type or model I should try. Also the wattage, how far above the canopy should the lights be.

I been using UVA and UVB lights for them and moved them up from a 14/10 to a 17/7 Light schedule. A mix of Purple Runts, Gods Gift, Scarface OG, whatever came from the shop I was smoking on.
uvb definition, Starting Out ($50-200) A reptile UVB bulb in a basic fixture runs $30-50 total and gives you a way to test the concept without major investment. Far-red LED strips for DIY setups cost $40-80 for a 4x4 area. Reality check though - you'll see some improvement, but don't expect dramatic transformations with budget gear. Serious Implementation ...
