Looking for highest PPFD per 4x4 rig?

[MMJ Dreaming 99]

When I say power, I mean PPFD. I guarantee I only need these three T1s for this 4x2 space. I could cover up to a 4.5x4.5.

What do you think you will pull dry from those plants? What are you using in nutes for that frostiness.....bro?

This kid's grow room is disgusting, who puts plants on nasty carpet like that, you just asking for mold issues.

9 of these can run up to 2700W, so i dont think youd be lacking for PPFD

Coco or Soil? Handwater or DRIP? What kind of nutes? Looking good.

Roots Organics Formula 707 + Roots Organics Dry Nutrients Player Pack + Roots Surge liquid catalyst. Handwater.

The frostiness, I say is the light paired with the Roots Organics stuff. I suspect anywhere between 400-500 grams altogether. I hear 1.5-1.7 GPW using COB is pretty typical.

you wont know if you need more light until those plants finish and you get a chance to trim the buds and see how much if any larf is down low.it looks like the floor is pretty dark in your pics @Olive Drab Green

Larf and just wait till the pm sets in with that overly compact cobbled cob growth

Watch and learn. It's pretty clear I'm killin' it. If I were getting inadequate light, my plant would be stretchy as fuck. As you can see, they are nice and compact.

You probably have the best looking plants on the site right now. I think people were just trying to give some helpful tips and things to look out for.

I didn't mean it like that. Like, I guess I'm still a bit defensive.

2 Pro-4's or 3's will provide HO over your whole 4'x4'.
I'll show you ppfd in my grow using 2, Pro-4's @ 25" spread apart on center. It's about 1100-1200 @ the height I chose & that's for a 5'x5'.

Fluence lights(spydr and vypr) are sphere and gonio tested, totally warrantied, IP65+ and ETL/UL. No guessing or mickey mouse math, nor does it need it.. That is real verified total system PPF.

No other light or kit brought up in this thread is close to what fluence is offering.

 

[Hybridway]

Fluence is a good one I think too. Probably the most even coverage available. The Bios Icurus had my attention at one point as well. The Timber Kits are well spaced for cobs.
I prefer the Pro-4's, enhanced cobs.

Awesome. So what other parts would I need besides the frame? What driver/ballast to run 9 of those? Any other parts? Please PM or post the specific parts? Will soldering be required?

Thank you.

depends how hard you want to run them. i recommend 100-160W for the best economy and efficiency, so at 160, 2 of them per hlg320h@2800 mA is a popular combo

NICE! And what are the Cacti you have growing?

I can't even imagine the 1825 at 160 watts! DAMN! I've run mine at about 75 watts and they are amazing!

yes, awesome commercial lights, no question.
But, hmmm... If I remember correctly, Growmau5's first DIY spanked his BML Spyder......

8-10 oz if we're betting guesses!
