HLG UVA supplement
mtnDEWDstarted grow question 3 years ago
Introduced this hlg 30 uva light as a supplement to the twin 260s. I've read just 3 hours a day increasing 1 hour per week up to 4-6 hours before harvest. Anyone recommend anything differently or just run it 18/6 with the lights?

I'd say run it while lights are on. But I give my plants more light then I probably should lol.
mtnDEWDanswered grow question 3 years ago
Thanks aquemini, I'm probably going to do that since it mocks an avg day outdoors basically.
GrowCN, will do. I also just ordered a FGI 730nm deep red 45" light bar to run with this uv light

I also run two HLG 260's but do not have a UV light. Please keep your diary updated and include some notes about your UV usage. I would love to see what works for you.

LEDs for 32x32 tentNew to indoor growing. Set up a 32x32 Vivosun tent. Currently have a giixer 1000w light, but wasn’t feeling the coverage was good enough for several plants. So I just ordered a second one. Do you think 2 giixer 1000w leds is ridiculous overkill?
Any thoughts appreciated.Week 2

Second light in one tent3 fan, 1 carbon filter, humidifier works inside and the tent is 120x120. I have 1 240w qb inside, i like it but i want more yield. So my question is i buy second 240w qb would it be good or it would disturb the balance? Also im afraid maybe electric bill will be too much to hide?Week 6

Low Humidity and high temp or high humidity and low temp?Do you think it’s better lower temp and higher humidity (like 27 degrees c and 80 % humidity) or higher temp and lower humidity (like 29 degrees c and 60 % humidity)? I’m just waiting for the humidifier but in the meanwhile I have to fix somehow. Thanks!Week 1

Lower lighting at switch to 12/12?Do you typically want to lower your lighting when you switch to 12/12?
I'm a little confused about what is meant when they say to have a 12" light distance for flowering and 18" for veg. Does that mean lower to 12" at the switch to 12/12, or just maintain a min 12" distance?5 years ago
