HLG 36 uva supplement

[bigdaddyg8]

any opinions on UVA supplement? HLG recently came out with HLG uva 36 QB board. supposedly to aid in resin production and essential oils. they say to use 4 hrs a day in combination with other lights the last 4 or 5 weeks of flower?

There is evidence that some fruits benefit from uva but i never saw a conclusive test on cannabis.

Uvb has been proven to increase thc content even if utilized only the last 2-3 weeks in flower.
