A grow light with UVA, UVB, and far-red
Dated 24 November 2021. Four channels split white plus 660 nm, far-red at 730 nm, and UVA 385 nm with UVB 310 nm. The note suggests UV for 2–4 hours a day in flower.
This note is from 24 November 2021. It describes a BAVAGREEN grow light with UVA, UVB, red, and far-red diodes, and four spectrum controls.
The channels, as published:
- White, 660 nm red, 730 nm far-red, 310 nm, and 385 nm.
- White and 660 nm red.
- Far-red at 730 nm.
- UVA at 385 nm and UVB at 310 nm.
The note states that UVB and UVA (290–400 nm) can raise THC concentration and yield, and it suggests UV for 2–4 hours a day in flowering. It also lists a smart app controller with dimming and timing.
That is the 2021 product note, not a crop recipe. Read the UV and far-red page and the May 2021 UV note before you treat the extra diodes as the main light. A 480W case with a UV booster shows one way the booster was paired with a bar.
