UV A And UV B In Late Flower

I grabbed the agromax uv t5 and hung it this week. My plants responded to it right away. I use350w 4k v29, 200w 3500k 3590 ....looks like the agromax spectrum was filling a open sweet spot.
How many did you get? Cost? How did you install them? I have lots of those very same CXB3590 3500K chips and I'm looking for an effective way to supplement them with some UVB.

My space is roughly 2x4 i suspended a single 4', t5 just under the bar. I has about 14-16" clearance from canopy. It isnt pretty but its bright.

The 3500k cxbs work great on their own as a flowering lamp. This plant was just flipped as i hung the t5 fixture. The response was immediate and obvious.

It was $35 shipped for just the tube. I already a basic single t5 fixture.

Why, thank you very much! Link me to your thread, please, I'd like to see how things turn out!

You were not forthcoming about how MUCH, mostly because we didn't know how to calculate it relative to the amount of light from the COB LED.

@testiclees has a setup just like my module, so I can watch and see how well his known quantity of UVB does.
Bro i apologize. I experienced a senior stoner moment. I remembered ordering the agromax tube. But the tube that i placed in my t5 fixture is the hortilux power veg fs +uv 54w.

I happen to have access to these, too. Anyway, let me know if you upgrade, meanwhile let the show continue!

As soon as i made the discovery i went to puchase an agromax. You can grab one on ebay for 37$. Im not sure that it would actually be an upgrade. Folks love the hortilux tubes and they have a good rep in horticulture. And it was that bulb that my girlrs responded to.

I think illl hold off on purchasing agromax until i observe at least some initial flower development while under the power veg.

Ill def keep you posted. I can put up some pics of sin mint cookies and kali china both just flipped under that rig.

this is sin mint cookies fem. She's had 3 weeks veg 18/6 then one week 14/10 with 730. Flipped to 12/12 on monday so 3 days 12/12 with 730. I had a few days with the hortilux t5 too close and it toasted the large fan edges. I've lowered the dosage time for the t5 and raised the the light rig. The plant is super dense and stocky. The shoots popping from the lowest stems are like small plants. I fimmed it 10 days ago so the tops look a lil screwy but I have no doubt this plant will deliver. (if there are no hermie issues)smc 1.jpg smc.jpg

Hey test & ttystikk can any of you guys provide me with a good source for both type of bulbs, I have 2 T5 fixtures (1) 2' x 4 bulbs (1) 2' x 8 bulbs. I'm currently coming up to week 4 of flower...I flipped on 3/10 would it be too late for using these bulbs or should I just leave it for my next run?

My current set up is a 4' x 4' x 9' closet with a 400 watt hps, but I would love to try a full run with just my T5's 2' x 8 bulb fixture of course.

The guy to ask is @RM3 cuz this is right in his wheelhouse. He'll know what brands, color temps, how many UV lamps, the works.

Interesting haven't heard of them, there's not much info on them but it seems there lights are not uv specific. Do you know what percentage of the light is uva and uvb as well as the penetration ,i know the penetration of the repti sun is 18-24 inches from the light (excluding the reflector) which is pretty darn good IMO. Why don't you like the reptile lights ? have you used the one's i previously mentioned?
Reptile bulbs are weak and only have an "effective" UV penetration distance of 18" from the bulb.........

That’s a bit of a generalization, but yes I do agree with you from the research I’ve done the Agromax does seem to be the better option (its puts out more uw/cm2 than the Reptisun and Arcadia) ,however I am perfectly happy with my 18 inch penetration as that's where most of the prime buds are. Its also worth noting that most reptile bulbs are still superior to the current led uv's. Another important factor that is being neglected is not just the intensity and spectra the light outputs but also the milliwatt maintenance of how fast, and to what amount the efficiency decreases over time.
