what’s good DGC family? Hope all is well with everyone’s health and grows . Soooo… 2 months after I bought the 550 r spec, HLG has a new light out I see, the 650 r spec with UV booster bar, but the booster bar can be added on to the 550. So question is, will the UV help a lot in resin production or anything else? What’s the benefit of UV light in my grow or is it a gimmick and don’t bother added it to my 550 light?
