Interesting things happen when you actually try something. Often, you get results you didn't expect.

tahts basically the reason i made this setup with 12 monos supporting the spectrum of a COB. try and maybe get something i never imagined i would get. lets see !

I did run cold water through my modules and I got exactly what I wanted; absolutely no heat in the grow room. Turns out this isn't half as beneficial as it sounds!

Allowing the water to heat up warmed the room, reduced RH and allows the plants to transpire better.

thats also a thing i only can tell after a testrun. maybe the heat generated is good like u said in terms of RH and plant transpire, maybe it is too much for the specific setup of the complete room and the room would overheat. may the circulation of the air inside the room and the fact that air is constantly pumped in and out can handle that extra energy that well so the room doesnt heat up that much at all ( maybe 1°C for example)

up to now i dont know but once the testrun is on i will keep this thread updated with all new informations i could get. I got a list of things to test here and this point alrdy stands on it so we will see

Using copper as a heat conductor is not the best choice with water based systems as copper tends to react negatively to the chemicals more aggressively than aluminum including ph variations, which is why you see when cooper is used it must be coated to create a barrier between the water and the copper. hard water, PH in water causes pitting in copper, which is why most hot water piping is made in PVC high pressure now. PVC is slicker, less friction than either copper or aluminum. heat transfer should take place in a designed heat transfer environment where the water cooling system is a closed loop and heat transfer occurs thru transfer of heat in a closed environment. Waste heats is removed and the liquid is returned to gather more heat and bring the heat to the heat exchanger with the east amount of loss en route. Aluminum makes a great water block for the initial heat transfer and copper would be less of a choice due to the potential of pitting and reacting with other chemicals

yeah if i would use the materials and made my own cooling block that might be a problem but i took an AiO-solution which came prefilled with obviously not only water inside so i think they took care of this. also the connections between the radiator and the pump-heatsink-block are made out of flexible PVC. all COB's got their very own closed up circle which at the end taking the same cooling medium from the growroom. this might be something to check in the testrun and even change if needed.

This looks like an awesome build. Especially interesting to see how all that blue supplemental light,spread out over various wavelengths affects tricome and resin production as the cobs normally just give a narrow peak around 450nm. Congrats on building maybe the coolest(no waterblock pun intended) light on riu
Check out @Malocan new light for something similar yet different.

Well done.

This is a knockoff of Amare Technologies LED Panels no water cooling needed

never heard of them, but as is saw the profile pic of a user here on RIU i googled and found out it is similar but with less monos.

In what universe? https://www.amaretechnology.com/shop-online

"Knockoff" implies something has been copied. @I0bob2016 claims to have known nothing about Amare. Coincidence maybe but not a copy. Looks somewhat more advanced, and I think Advanced had a similar design some time ago with the tech available at the time.

Seeing how Bob incorporated 12 different wavelengths on 12 different dimmers, I'd call it a completely different animal.

Hook Bob's unit up to one of VegasWinners controllers and you have a really useful tool for determining whether or not Amare's claims of "perfect spectrum" are anything more than marketing hyperbole (they aren't).

Please just pipe down with the Amare puffery little guy, even Hybridway was able to put down the kool-aid for this thread.

Hook the light controller up to a sound sensor and you could have an awesome piece of event lighting!

nice idea, making it multi usable for growing and partying hahaha love it

There's a HUGE difference between surrounding a cob with monos to enhance spectrums (ala Amare) and how they are driven

so lets say, if i turn up all dimmers to 100% power i end up with a spectrum enhanced amare.

for me its ok to say this cause as i mentioned before i didnt know anything about amare ( or similar ) as i started to plan and actually build this complete thing.

You really will jump at any opportunity to shout your overstated involvement with a totally average lightmaker from the rooftops.

Your "expertise" is pure fantasy.

We'll never know what spectrum works best in what application with what strain until we have a tool that can incrementally and reliably adjust the spectrum. Neither your hallowed Amare, nor your forgotten Spydr can provide that kind of control. If you cant see the value in the tool Bob built and all youre here to do is spew your aspergery, non-sequitur horseshit then please find the door!

100 monkey syndrome? Proof of collective conscious thinking when we are on a similar path.

Several years ago I approached then BML (now Fluence )he made separate veg and flower lights @ some crazy price like $2K each. I told him I could design a SPYDR 600 (360w) spectrum blend that could be used for both veg and flower, which would bring him a lot more customers.

I wanted 2-4 of the 6 bars to be on separate switches so I could introduce them as needed for early and late flower. His production line was not equipped for anything but all 6 bars having identical spectrums, although I was able to mix spectrums within one bar.

Here it is in action with ~ 7 days to harvest. Begging the question How much better would complicating the light be? You would need a side-by-side, but I think it's as good as my Amares, although the mono rings around each cob is on a separate switch which I use alone during veg

Anytime you start hearing from a bunch of naysayers you can be sure you're walking a different path. People are terrified of anything different.

Take it from me, the guy who runs vertical grows at scale, developed water cooled COB LED modules, made full sized plants portable, etc, etc...

Not sure if this would help here but I've experimented w/ colored t-5's in veg. For about a year to see my plant responses.
Not sure if anyone else has noticed it & now w/ the Hortilux Power Veg line up (all the ranges of colors) people can determine more for themselves or at least have the opportunity w/o having to buy tubes online from coral companies.
I noticed negative plant responses from the Atinic (Blue) bulbs. With that said, I feel they prefer their blues to come from white bulbs or sources.
So maybe have your grower try the blues w/ the cobs n shut the others down when you get a chance. If you find the same thing happens (my Atinics were mixed w/ whites) then maybe focus on just filling the gaps w/ the blues on low power under & above 450nm n shut off the 450. Amare uses 65k for their blue w/ one 470 around each cob. Fills the spectrum nicely. Maybe they saw the same thing in testing. Dunno.
Just something to try out seeing how you can here. Maybe the blend w/ a higher power white source (cob) makes this a mute point. Interested to see.
As for the rest, I think it's great that you have a tunable spectrum to determine the end result. How else could you.

Pet, nice work on that plant BTW! Looking good!

There is a company doing this already but w/ unmentioned components. Not sure if they're using the complete range as you are.
