The QB says ppf 1450 for 4×4 space

The cob says ppf 750 for 4×4 space.


I've heard that tha quantoum kit isn't as evenly distributed as the that cob kit
And I'm doing SOG from clone.

And Wich one runs coolest?

I’ve got a 12 vero 29 cob Rapid kit, love it. I only grow off season as I’m near Sacramento and it’s too hot outside, so my temps are never were much of a concern. Probably be adding a second this fall. When each of the cobs are only driven at 50 watts per unit, no extra cooling is necessary (IE-fans and such, the cooling is taken care of with the heat sinks) Tough to go wrong with either choice, I think.

Coverage in a 4x4 space with quantum board lighting. Just wish I had even coverage lol

We are essentially running the same wattage. Neither requires extra cooling aside from standard ventilation. I would love to build a cob set up exactly like yours and run it side by side my quantum’s and see how they truly compare. Your setup looks tight bro, can you comment on your source, and total cost?

Injst don't understand..
How does it have more coverage..

And what Abt the boards put oof way more um/Jules
And way more ppf...

I love my quantum boards

How many do you use in what space?

How many do you use in what space?

I’m running 9 132qb in 4x4 spaces. With digital multimeter displays and full dimmer capabilities so I can adjust intensity as well as height.

That’s some sexy tech/hardware

I know timber led is now having that as a option and a complete for their led’s ( I run 2/6 of my light of them, 4/6 spydrx plus)

Would love to test it under a par meter and under my flood table and see how my plants react. Someday or at least watch people online lol

quantum. :) save on the heatsinks and rails

Save all the way. Build it ourself and get more watts for half the money

Ugh inneed Ed the fixture two weeks ago..

So need plug and play.

 

[Randomdred]

And I decided on two of these

One this week and another..
Well hopefully the following week..

Or this, it's my build.

Read the entire post because I went with a stronger power supply, 360, in the end.
