Is UV missing in your grow room?
Dated 18 May 2021. The note says UVB and UVA (290–400 nm) are in sunlight, suggests UVB late in flower, and warns that UVB can burn skin and eyes.
This note is from 18 May 2021.
It says UVB and UVA (290–400 nm) are present in sunlight. It says UVB pushes plants to produce more THC, describing THC as a coating on trichomes that filters UVB, and that UVB can increase terpenes, which changes smell and flavour. The suggested window is the last two or three weeks of flowering.
UVB is dangerous. The note warns that it can give you a sunburn and can damage your eyes if you look closely at it. Do not treat a booster as a lamp you inspect up close.
The product in the note is a BAVAGREEN UVA+UVB booster. Current fixtures with those diodes are on the UV and far-red page. A later note, four spectrum channels, splits UV onto its own switch. A 480W case shows a bar sold with that booster.
