HLG 30 UVA SUPPLEMENT

[Doug Dawson]

Hello all. Just put an HLG 600 in a 4x4 tent and have 4 plants underneath it. I am wondering if anyone has tried the HLG UVA supplemental light and if so what did it do for you? I just ordered this bolt on addition to my light but wonder if anyone has used one?

Im using rapid led 12w UVA and a red obviously. I've gone mad trying to figure it out as well. Mixed reviews bc of UVB. Here is an article I found that has at least some positives .

Lighting Strategies for Higher Terpene and THC Content in Cannabis

The type of ultra-violet light you use makes all the difference for getting the most out of your plants.

I'm running mine 3-4 hours during midday light cycle 17-20". Can't tell yet but buds are getting frosty

Anyone else use supplemental UVA or specifically the one quoted?

Better off mounting an Agromax Pure UV T5 bulb to your fixture. Less than 1/3 of the price and has UVA & UVB at much higher concentrations.

HMMM, that is interesting. I already purchased the HLG to go with my light but after a run I may buy one and try it to see the difference. Can't seem to find that in Canada and with conversion rate, shipping and possible duties will be a bit more than 1/3 the price, but still a little over half if they don't change me import/duty. Thanks, I will look into them for the future.

How’s that UVA bar been treating you Doug? I’ve got one clipped on my scorpion, just starting week 3 and starting to use it. Any recommendation for on/off times?

Not really. It says to use 12/12. I am starting 3rd week of flower so I put it on a few days ago. As far as I know you leave it on the same times as the main light. I like the look of the Scorpion, came out just after I bought my 600. Looks like a really nice light.

Edit: The site says to use it 12/12 which told me it is for flower cycle. Plants not creating trichomes in veg so may not be useful at that stage. That said I cannot say for sure.

Personally I would think it would be beneficial the whole time, but at least the whole time in flower. It's only like 30 watts so why not run it all the time.
I know this info is mainly about UVB, but it might help.

The Solarcure is what @Stephenj37826 from HLG said was a good choice for UV. Or UVB more specifically.

Great link, thanks @PadawanWarrior , great link.

 

[Dape Green]

Thanks for the link Padawan. There gonna end up being a uva, uvb and far red bar hanging off this damn thing.

I think I’ll start it at a 50% run time and ramp it up to full time Except the first and last hour over a week or two.

I hooked one up at the start of flowering about a week and a half ago I see no harm done there's still doing fine
