I have started using uvb again now we have proper intensity to actually make a difference. The LED UV is in the wrong range and for the THC receptors to open it needs to be in the 310-320nn range. I have 1 tube per 120cm sq. it’s 50cm from canapy and comes on for 2 hours in the middle of light hours for the last 4 weeks of flower. I’m growing the same 2 plants I have all year and this round you really notice the resin production, taste and potency. There are experiments all over using aromatic plants as well as cannabis for increased oils. There are a few dubious UV lights out there that are too much in the UVA spectrum and all they do is frazzle the plant. I’ve tried reptile lamps and they are to weak. Have a good look around there is some interesting research being done and yes it does increase potency etc.
