You sure on that? I'd only need to veg for that and I made my eyes bleed looking up how to diy cob today, basing this off of HydroRed, he using only 4 for a 40x40 inch space veg and it's doing well

I have no idea what HydroRed has built, but 48 x 48 is bigger. So yeah, add two more. These are the strips I would get:

And this is the power supply:

No soldering is needed, the strips have self-locking push in connectors.

I understand how to make a frame and make the apparatus to mount everything to and can do that well, but have no idea what hardware you just mentionned

Could you explain the lights/driver type pieces that need to be bought and pieced together?? Lots of solderring etc?? Specifically if the 10 strips total you mentiioned at the end could be run off of the same driver.

Would appreciate that to the moon

Thanks guys, I'll look into it tomorrow, when I say that I mean do what I did today and be like a horned lizard squirting blood out of my eyes cuz I legit went from 'what's a cob' to being able to build one if I was in a warehouse with no internet, cuz if you gonna do something don't half ass it right, I'm tired as hell so tonight I'm turning brain off. But seriously thanks for all this info on it, always looking for the best shit.

It wouldn't be terrible, but no where near what the 44" LED strips would provide. Check this PPFD chart I made for my samsung strip build. Better coverage than 20 cobs provide in a 4x4. Yea, 20. I know this because I have a PPFD chart saved of a 20 CXB3590 cob build in a 4x4 tent and it is no where near this good haha

That is indeed a very insane coverage zone

How's the penetration as well? Another somewhat important detail is I plan to probably grow 4 trees in the tent, would that be a major factor? Cuz idk virtually anything about the light penetration and spread of these lights. Cuz if they have a very good spread but can't go very deep that wouldn't be very ideal (the led strips)

My honest review of my VIPARSPECTRA 900 REFLECTOR SERIES.
Penetration = shithouse
Canopy = scrog essential = no trees.
Save your hard earned money. Buy something better.
I hope this expresses my distaste for VIPARSPECTRA.

You'll get something to smoke. For sure.
But just a little extra cash, will get you a Ferrari. Instead of a Daihatsu.

That's my honest, user review.
IMHO. Anyone that says otherwise, works for VIPARSPECTRA.
The diodes don't last for shit either. Then they say to send it to the factory to get fixed, under the 3 year warranty. That's all well and good. But what about light for the 3 months it takes to get fixed.
You pay the shipping and freight, back to China for the warranty too.
They're con artists.
Buy something better.

Thanks for lifting the curtain bro, personally I think they try to be like a knockoff of kind leds just in the design so people see the price and get Venus fly trapped lol (edit: it's my new opinion after more research, originally just saw them and they didn't look half bad

I agree, especially their "PAR" series!

I laugh at viparspectra harder than the other chinese blurple manufacturers because they use 2 different orange diodes, a yellow diode, and more 7500k than 3000k whites lol. Oh yeah, and there's almost as many IR diodes on their panels as red diodes!

So much blue too!

They take christmas tree light to the next level

Yeah man.
They honestly look good on paper.
But just don't stack up at all.

Lol Christmas lights :clap:
That's a very accurate description.
The blue was a pain in the ass too. Stunted the shit out of young plants. Leaf curl and everything.
I'm glad someone brought that up.

Sorry missed your question.


The more spread your light sources, the better the penetration as long as the overall intensity is the same. the PPFD at 12" is 727 and the PPFD at 18" is 695. Almost no change. That means the goldilocks zone (zone in which the intensity is optimal) is big.

It's a myth that purely intensity makes for better penetration.

@nfhiggs did a great diagram on it here https://www.rollitup.org/t/new-light-or.958507/page-12#post-14067829

Yeah I just saw the chart in another thread just without as much description. Reading the whole thing has it making a lot more sense now, if I can get the strips to be cost effective that's probably what id go for, thanks man

They work good for me as a beginner and i have no complaints...ive even had a long time grower look at the growth and is surprise with them...got 14 oz of 2 plants that were bag seeds. These are the clones.

im not sure why anybody would be surprised that lights grow plants. the "evidence" that "yes this light can grow a plant" appeals to people who literally know nothing about lighting. it is absolutely uncorrelated with "this is the best (or even a decent) lighting option for growing plants"

you can grow fantastic product with sunlight, christmas lights, hps, mh, T5, CFL, etc etc.

you just need to use a lot more power to do so in many cases

Lol any light will work until you gotta light up a real area, getting a larger space lit with enough light per square foot would be where things start faltering. Yeah same thing in different words but meh
