I just put a UV bulb in my T5 rack with fast and vast one bulb 30 bucks hope it works
I'm hoping you grabbed one of the 54w 46" t5 bulbs, in my article, i recommend the other type, but I need to update that, those 46" t5s cover a 40" area pretty well, you will see an increase in resin production, it's science, my man!
