Anyone ever run 4 Vero 29's on the Mean Well HLG-320H-C2100B.

Looking at the datasheets it looks like it will work. Vero @ 2.1A = 38.0 Vf. Driver says 152..

Would just hate to buy everything and realize it wont power them up...

 

[Hybridway]

How much the pro 3's running $?$?$ ... i think i like the 2x4,3x4 foot print builds the most.

Your best bet is to e-mail. He offers sales allot.

HPS is the light to beat for flowering but T5HOs and MH are the light to beat for vegging. do LEDs produce a significant increase in quality and/or yield? if so is the gain worth the substantial increase in cost? I'm a PU MMJ grower. not a commercial grower so I make no profit from my grow. i'm just growing medicine for myself and my S.O. my main grow room is a 2ft by 6ft by 8ft closet where I grow 4 plants under T5HOs and get about 0.7 GPW. I have a 2ft by 2 ft by 8 ft closet where I conduct experimental LED grows.so far I have tried a 300 watt mars hydro and 4 DIY grow lights using cree 3070s ,and vero 18s. I have 4 citizen high CRI (90 cri) diodes on order for my next test grow but so far have not found a configuration that will out perform my T5HOs using a mix of 6500k and flora suns.LED makers are doing themselves no favors with their exaggerated claims. and why are they charging $600-$1200 for a light that I can build for $75-$150 ?I am still trying to find a good 430nm diode that won't break the bank to help fill in the spectrum. I believe that broad spectrum blue light is important to strong healthy plant growth

your nuts if you think T5HOs can beat cobs for BOTH efficiency and spectrum.

A good LED light will allow you a substantially higher GPW then other light sources.
Also, depending on the spectrum of your led, they can produce a higher Terpen profile & THC content.
They also produce a differant type of heat that will make it allot easier to cool your room, eliminating the need for extra fans & duct-work.
I feel they are worth the initial investment, but only if you're buying a good one. I think buying a crappy one totally defeats the purpose & leaves growers new to LED thinking they all suck. Then you miss out all together & got beat for a light.
This is how some companies take advantage of consumers. By riding the coat-tails of the good companies whom do produce better results w/ less energy.
Then people think all LEDs do. Fact is, not all will give you these desired results. That's why it is so important to buy quality from a trusted comp.
The key is to be aware of false claims & do some research. Look for proven results. Talk to others that own the light you're considering & take into account whether those people have any experience growing w/ HPS. More often then not, you'll hear people saying their led performs better then HPS, but they don't actually know from experience. That's the worst.
No, actually the worst is when people who do not grow or own a light recommends a comp. Unfortunetly, you may see allot of that here these days. Watch out for those guys the most. They are full of misconstrued evidence,& misinformation. They may also overwhelm you with data-sheets that they can't actually apply to growing themselves because they don't grow or own any light. Feel me?!
If you pay attention though, it's not to hard to get past the BS.
GoodLuck!

your nuts if you think T5HOs can beat cobs for BOTH efficiency and spectrum.

He said in Club T5 that he has an IQ of 165. You will lose automatically if you try arguing with him.

theory may be a good starting point but any engineer can tell you that they usually don't work in the real world without a lot of "tweaking". you are smarter than me. I only tested 165 but I understand what you went thru

... which was in response to this little nugget....

In 4th grade they tested me and said I had an IQ of 169. ... Enrolling in 9th grade ... they said no I quit

You can't win against genius!

don't know about that. I just look at the way they grow plants. in my test grows.

Classic @Hybridway

Just remember, this is what he really believes:

I've seen a few all white COB vs HPS & almost every time they Yeild pretty much the same thing in volume.
So around .7 GPW.

By the way, he has also never grown white COBs only, and is apparently really, really bad at googling. And math. And doing anything but yelling about datasheets when he gets confused and saying shit like:

The full spectrum showed me highly increased morphology.

with a straight face.

I don't really have a point. I just really like him.

 

[mauricem00]

Exactly! Here is cheap supplemental colors that you could add to DIY cobs
https://www.fluence.science/product/ray66/

So that and cobs would be pretty epic.

thank you but i'm actually playing with individual diodes. and not complete plug and play grow lights. currently i'm playing with fine tuning the spectrum and looking at high CRI whites and monochromatic leds to accomplish that.theory may be a good starting point but it usually does not work in the real world without a lot of fine tuning.

sure does seem to be a lot of hate and discontent around here. I thought weed was suppose to make you mellow.

the average grow for cannabis is 0.56 GPW so 0.7 gpw is not bad and my grow keeps the medicine bowl full. thats all I really care about.

Naw, it's fine. But either LEDs are more efficient or they aren't. If they are, then gpw is going up, period.

And well, throw a rock around here and you are above 1 gpw, if that's your metric for a successful grow. Including documented grows on youtube from well-known members.

You're a joke!
I love how you take little clips of what I say & mix them up in attempts to discredit me.
I said I found those results when looking into side by sides more then once.
I also said I Probobly used the wrong wording & try to explain things as simple as possible. Lol!
I do not use many math equations to grow & yet grow very well. The key here is that I grow. Not little things either. It's very important to me That I yield as much as possible. So I cannot afford to compromise my crop in any way.
With that said, I am a much more reliable source of information about things I have real experience with then you by a long shot.
Anyone taking advice from you about anything other then data isn't going to fair well. And then they need to take into account that the data you puke is only info repeated by someone else down the line.
You do not know anything first hand but are all over a growing forum giving advice.
Growing is not a joke. Therefore, giving bad advice about things you don't understand could cost someone tons of lost money's.
You are only hurting others grows & wallets. Never mind confusing them with talk of how you relate math to growing, trying to make sense out of it. Which would be great if you actually grew & could apply these things to real life situations.
I may not be a geek or nerd but I grow effectively & efficiently. I do this full time. Everything depends on my success.
So, how is it that you should be a source of advice to anyone about growing?
Better yet, why are you on a forum with growers at all?
You should kick rocks IMO.

efficiency is only a small part of the equation. LPS lights are extremely efficient but they do not grow plants well

The thing is, I've had MH, HPS, CFL over plants and tanks for waaay too long. Started building LEDs ummm about 5 years ago to grow coral, had to figure lots of stuff out, like all DIYers, and really understand this shit somewhat.

And you know what never surprised me? Pretty much anything. Pretty much every light source has performed in the real world how it should on paper, within a certain margin of error. PAR watts are PAR watts, photons are photons, and different bulbs and leds from reputable manufacturers all did exactly what I expected.

Including the latest light I built. Output on a shitty lux meter, temperatures, power usage, it all lined up with what I expected.

So when you say Amare is sooooo much better than a COB-only light, and say COBs have the same gpw as HPS, it's bullshit. I know it's bullshit, because a million photos and videos show it's bullshit, my experience not being overly surprised by simple math shows it's bullshit, data sheets and manufacturer testing from HID and LED companies show, guess what? Bullshit.

And for somebody who grows sooo much and sooo awesome, you haven't even tried a COB grow, but continue to push one brand of lighting that you are having success with, and crediting that success to pretty colors instead of the big ass COBs in the middle of it.

Sure, but white LEDs are not LPS. Unless everybody is lying around here.

 

[churchhaze]

sure does seem to be a lot of hate and discontent around here. I thought weed was suppose to make you mellow.

Then stop talking out of your ass about efficiency. Again from Club T5, here's what you have to say about T5HO...

my 4 bulb fixture produces 64,2 watts of radiant power. it draws 236 watts at cold start up dropping to 203 watts after 10 minute warm up period using a plusrite commercial ballast ( ballast factor 1.0). thats 31.6% efficiency. better than a 150 watt HPS or 250 watt MH. it also beats the 3 watt bridgelux LEDs I've tested.after 2 years of continuous use averaging 15 hours a day (veg/flower) my light meter shows a 5% drop in output which agrees with the manufacturers L95 rating . I do not use bulbs from the hydro shop. I use commercial bulbs from plusrite or global. these seed hit soil 4 weeks ago.

So I went and did an analysis on the specific lamps you insisted were better than the older tech... Here's the results of my analysis:



Radiant efficiency of 27.4%.

Then in the same thread, it seems like the post was deleted... but paraphrasing, he was saying that our COB builds are closer to 35% efficiency and that our calculations are essentially bullshit. (yet he somehow came up with 35%)

Maybe if you would quit lying I'd give you less shit.

the average grow for cannabis is 0.56 GPW so 0.7 gpw is not bad and my grow keeps the medicine bowl full. thats all I really care about.

Most of us are pulling over 1gpw with ease. My record so far is 1.6gpw with cxb2530 3000k 80cri u2 at 500mA.

A good LED light will allow you a substantially higher GPW then other light sources.
Also, depending on the spectrum of your led, they can produce a higher Terpen profile & THC content.

Citations please.

Good lord, it is one thing to develop a theory based with some quantitative data at the very least. Have you ever looked up the word: hubris, in the dictionary?

Are you pulling lab tests at all?, just curious.

Something like SC labs test results for Terp profile/ Cannibinoid content would be nice.
I just got a quote a for $65 a sample for 3.5 grams. Ouch. and I need 10 or so.

Which spectrum is better? I genuinely ask that.
