If u suppliment w t5 be careful. Hortilux power veg is part uv, agromax's pure UV brand is pure UV, unlike guy at the store told me, he said they were basically same bulb just different names... fried my face and my girls.... PureUV is not just a branding name its pure uv, they can be used but not full time like hortilux ones can be, so in t5 u kinda have choice of short powerful bursts vs a bit all the time. Just a fyi if you venture out of led for uv..

I've seen respected LED grow light manufacturers add fluorescent UV bulbs to their fixtures for UV if that gives you any indication....
The Amare light with the small single fluorescent UV tube int the middle is a joke ! Only window
dressing to sell more already over priced units !

Check out the Arcadia reptile UVA/B bulb. D3 + 12% UV.

I've had excellent results with the Agromax Pure UV bulb. I put mine in a single t5 fixture mounted down the middle of my cob fixture. It is extremely powerful though so you need to be aware of not working in the grow room when it is on, and it's a good idea to keep it a fair distance from the plants. I haven't looked much into true UV LEDs, but it would probably be easier and more cost effective to just throw a UV t5 in your tent.

The concept is sound though... I've seen many people running cobs put a single UV t5 down the middle.

I have wondered at times why the guys running DWC etc don't run simple pond UV lights in their piping, heck you get large aquarium filters with pumps and UV lights build in that moves serious water.
As for LEDs, yes you get VERY expensive UV LEDS, but there are others on the market. I have built a small UV LED panel I use to etch circuit boards.

Pretty sure he's not asking about UV for sterilizing his water. But to answer your question, its an unnecessary addition of heat, electricity use and of course one more thing to potentially fail - some pool shock or h202 works just as good for a sterile rez.

Oh I’m sure they can be used well, mine were just too close and or on too long which with the hortilux I had before was fine. Yea they sunburnt me BAD. All on one side of my face which was cute. But they put a crispin to my county fair girl. She finished off pretty good quality wise but never grew more bulk after that day and it was only about 5 weeks in. Damn shame too cuz she was a beast- begged a year- topped a million times, LSTed flat to fill my whole 6x6 room and she was cranking till I fried her. Lots of hash bud and that that wasn’t was a B to trim!

Not the bulbs fault but the user...

You guys need to be more careful with the UV and turn it off when in the room and wear good eye protection. Not only can it cause skin cancer but also cataracts.

Yeah, when I made those boards I didn't wear eye protection. It literally feels like you got sand in your eyes. Not fun.

Yes you need to be very careful with it, I run mine for 15 minutes at a time, starting at 3 times a day, eventually ramping up to 6 times a day. I also keep my cob fixture around 24-30" above the canopy and not 6-8" like some. If I kept my fixture that low the UV would burn the shit out of my plants lol.

Yes definitely, that's why I stressed to be aware of when the timer clicks on for the UV. You can get nasty burns very quickly from these bulbs, they are no joke.

I peeled for two weeks!!!! They are no joke!

I will use mine again, I was gun shy this run I will admit after loosing the most beautiful girl I ever grew to it, granted my fault, but I needed a good run, and went back to the KISS method for a run. I'll get a cycle timer to put em on next run 15 mins a few times a day next run.
