So you do not have enough brains to use the Internet correctly and look for information, that's all.

@@lilokino94 he's complimenting the video. No need to be an ass towards him bro. He's probably a beginner and didn't find as much information via the internet than he did in this video. No need to be rude.

Anyone being rude is just trying to push their short comings onto someone else. #asshat

Yes.

@Andrew Brent She probably means it is too light green- as in not enough nitrogen in the pots(?)

Yeah, i am also very interested to see a test for the California lightworks t5. Looks very similar to the AgroMax by form, light color, spectrum ....

I know it's been a while but California light works recommends the Agromax pure UV as a replacement bulb so I have read.

In a California lightworks video, the guy says you could runb it for 6 hours straight

Hi, Fluorescent is still best, the UVB LED diodes are not efficient and are expensive. Thanks.

The UVB fixture I bought from California light works is chrome inside and out. And its not cheap.

i use 630,s cmh but switching to led soon light rail systems look like the best ppfd you can get atm with 2.8 efficiency... can you test one of them

The UV from your CMH bulb is unlikely to deliver any UVB. Lots of UVA but that is useless for resin/oil production.

I dont press

@@localgrowguy3149 do you consume it? If so better with UVB.

Just a smoker but im going to look into it

I second this! Also, there's some discussion that the Agromax PureUV seem to burn plants. Is there UVc radiation being put out? Some seem to claim that there could be wavelengths down around 270nm being given off. Anyway to test for UVc?

I wonder if the uvb causing resin production simply causes cannabalization like during flushing or actually is bleaching the flower... either way both can be fixed but the cannabalizism is good in my eyes cause I only add uvb during flush after using the eye hortilux blue mh->ceramic hps both 600w (Ive been tinkering with a sativa blend indoor so I need blue during veg to help with height after trying other wise hps them all the way through for massive ladies..). I wonder if they just needa move it back some or simply remove its reflector/lower its efficiency (remove some reflective/coat some surface..)

@@prestontingley8914 UVB or any UV to my knowledge doesn't cause cannibalization directly ime. And if you're getting bleached tops or burnt leaves its simply too much light, UV, even too much heat. My UV lamps stay on with my reg lights bout 24" to 18" from canopy and all my leaves point up right at my UV lights. I turn them on when I flip the lights to 12/12, some people like to use it in veg too but I haven't seen much benefit doing so. I use T5 ho 14% UVB Acadia bulbs as said in my original comment. Change them every 6 months of useage for best results, the UV output drops as bulbs get used. Back to your question one could assume the increase in THC from UVB exposure might make the plant need/use more nutes. Although one wouldn't think it would be much of a metabolic increase considering the THC increase is only around 25% by ratio. But this could lead said plants to cannibalizing but not bleaching given the rare situation but I'd doubt it as much of a factor tbh. That's my best theory for you friend, a majority of growing knowledge isn't proven its anecdotal for the most part. So take it with a grain of salt but I pride my myself on correctness so I'm not the guy spreading total bs bro science hurting the community instead of helping it. I'd recommend you learn to build some LED lights with HLG boards. It's easy man and super worth while. It'll help alot with heat overall which is probably your issue from what it sounds like. But if you're dead set on HIDs the 315 CMH\LECs with bulbs in 3100k are perfect for full cycle vs the ceramic HPS which has a poor spectrum in comparison. Also you can use them for full cycle no need to change lights or bulb from veg to flower. Also the 315w versions have the most options and its not a total death ray in the center of the light footprint like with more powerful lights which I think is most likely your issue. The 630w CMHs with 2 315w bulbs are the best of the HIDs even over the DE versions they bring more to the table. But if I was you I'd finish my crop if I had one going then sell that light and learn to build a LED light. Specifically HLG best price, high efficiency/low heat output, best tech, best spectrum. Happy growing man.

What i understood ..is .. 2-3 hours totally ( 1 hour each time ) ..during daylight cycle... 🥴

Why so overpriced ??

A B I’m of the opinion the FS + UV bulb by hortilux is wonderful for filling out the spectrum that you are losing from the glass blocking spectrum from air cooled hoods, and for getting w/e is lacking from your led spectrum. If you want actual UV supplementation, the AgroMax bulb is better. I would like to hear Migro’s opinion on this as well.

They are supposed to supplement the light copying the effect of sunrise and sunset. So the conventional wisdom would be to turn it on with the rest of the lights but UV for a short period when all the lights turn on and a short period before all the lights go out. There is a Nasa funded researcher who gets into all details. Maximizing Cannabis Yields with Dr Bruce Bugb. RU-vid.

For solacure you would need 4 X 1 meter for your set up (2 hung on each M600 frame), not used agromax.

Also found this T5 fixture with bare metal shiny reflector www.amazon.com/gp/product/B015TL6T2W/ref=ox_sc_act_title_1?smid=A2ITYAZGUJNKX4&psc=1

@@MRBROWSER2012 thank you for the link, how did these work out for you. I'm interested in them.

I bought some Agromax pure UVA 25% - UVB 75% 45 watts t5, and the Agromax plus UVA 45watt t5, and the 10,000k finisher bulbs there the best, I immediately noticed the difference like night and day, I've been growing the same Runtz strain for over a year now and when I added the UV spectrum they noticeably got more potent more trich's, I run them for an hour a day( right at the halfway mark of my lighting schedule simulating High Noon 12:00), then constantly/12hours with my LED's at the end of flower ( I even hit my plants in flowering with UVC to kill all mold spores, it really works, I run 40-60% humidity in flower the resin damn-near be running down the stems from the buds) I run the UVC 3mins a day twice a day sun up and sun down (in flower 3 times a day one extra time mid day/high noon/in the middle of the light schedule) ...... ✌❤

@@ronevergrow8319 Yep I use UVC and Ozone to keep WPM under control. Bought a cheap UVC bulb and hand wand the plants, works great to kill mildew. just getting started with UVB though this week though. Looking forward to monitoring results

HTGSUPPLY.COM

D4rk BliZz4rd UV is strongest when sun is closest to earth. As the earth rotates the UV strength increases and decreases in direct proportion, sun typically is closest to earth at noon. See Perihelion and Aphelion, those calendar dates when sun is closest and furthest from earth. At more acute angles the UV is scattered by the atmosphere.

Also he mentions that the bulb puts out much more UV than natural sunlight. I believe that he meant to run the uv no more than an hour, and to do that no more than twice a light cycle.

I have a small space and I'm considering doing something like that how did it work out for you?

@@chuckwaardenburg496 I dont think it made much of a difference but a stronger output might have a difference. It's hard to tell since other variables also changed

@@Sum1t54 Thank you for responding. You know we're always trying to look for that supermagical ingredient..

Do you use reflectors? What cycle do you use?

@@MIGROLIGHT hello, is my first grow with uvb and with white reflectors (metal white paint), 1rst week 15min on 45 min off (6 times on ) , 2nd week and running, 30 min on 30 min off (7 times on)... with hlg led lights, a couple of plants are 30 cm from de bulb and they seem good, but a couple of small week plants show light burn

I use em too.

Hows your results till today? Just curious.

Adam I've been patiently looking forward to your report.

He explained that UVB LED's are prohibitively expensive. What more do you want ?

@@Baldnesz moron I am not asking about uvb or about uv bulbs... Look up what I asked before you talk out of your rat brain.

Here you go friend HTGSUPPLY.COM

It's where I get mine in Michigan.

Thanks I looked there a few weeks back and they were out of stock

Doubting Thomas lol

solarcsystems dot ca has the Phillips Broadband UVB bulb he tested for 80 bux, agromax don't ship to canada and no local suppliers

I bought through a distributor called UBUY. I had to pay a lot of extras but the total was about $90 for two.

If your local garden center carries generic t5 bulbs they can order the AgroMax brand to sell

@@MIGROLIGHT Thanks for your reply. Unfortunately when I try UBUY it doesn't include UVB bulbs, I've tried lots of different search terms but no luck. I can get 2 X Arcadia T5 Dragon Lamp 14% UVB - 24w delivered for £49.27. It may be better to use Arcadia D3+ Reptile Lamp T5 12% UVB which I can get delivered for £47.07 and can be set at the same height as your MIGRO lights and should cover a 2' X 2' square nicely at that height without damaging the plants. The 14% UVB may need to be set higher than the MIGRO lights Could you also comment on the light spectrum charts shown on the arcadiareptile website @ the bottom of the www.arcadiareptile.com/lighting/prot5/ page.

@@juliankirby9880 Thanks for your reply, I live way out in the sticks so there isn't a "local" garden cente to me, nearest is 80+ miles away so I'd like to buy by mail order.

Shhhhh. People dont like facts. They'd rather waste money on the newest trend. Lol

Great comment. The tighter the wavelength, the further it carries without falling apart.

It's a Bell curve. Joules go up exponentially as the frequency increases. 1 photon @ 285nm has more energy than 1000 photos at 315nm.

In laments terms please gentlemen. 😊

Also interested in the response.

​@@engell3707 the black lights block out all of the spectrum except the UV and regular fluorescent bulbs dont have the much UV in them to begin with then it is safe to assume they are not great at producing UV, because they are just allowing what UV that IS present in the spectrum through and blocking everything else - is pretty much what he was saying
