I have to completely BASH water cooling any grow room.....

I do not understand how it is ever going to be any kind of efficient.. Chiller, multiple pumps, hoses, shut off valves ect, ect. Like if a 1/4hp chiller has trouble keeping a single 1000 watt bulb cool along with the room cool, which it will have a hard time with a constant running chiller, which you better have outside or you open up a whole other bag of shit... More extra tubing more pump power.
Ok now all that vs, lets just stick with simple here, and go with a 1000btu portable ac. Ya cant use co2 efficiently but if ur only growing with one to 3 lights is co2 going to be worth it. Answer is no co2 will not be worth the trouble under 3k watts.. So there you have apx 1000 watts running 12hrs ish with the ac and add up all the watts with a chiller water cooled grow and you surpass 1000. Not to mention all the humidity water cooled brings. Add in a dehumidifier. Im using diy open reflectors out of aluminum jacketing in order to get better spread light in my closet. When i had more plants i ran 2 diy reflectors with portable in the closet duct straight into the attic crawl space closet is about 5x6 and i had 1600 watts cooled to 75 constant lights on by simply positioning the unit where it blew straight on the 1000 buld then the 600 kind of inline. A 1/4 hp chiller couldnt even keep it below 80 with high humidity... So give the finger to using a chiller for anything but your nutrient tank.​

I use inline power steering pump coolers in cunjunction with a 1/4 hp chiller and 1 pump to chill multiple resevoirs-and then spray my roots at the end of the line where it is recycled back to the pump res.
I could take one of these power steering pump radiators and place it inline- in front of a fan for added room cooling- for 0$.
This seems like a pretty efficient way to use the tools and supplies i already have available..

I would never think of trying to cool a room completely with water/air though.. i have a large air conditioner to add cool air when needed through the intake fan.

My chiller is inside my 8x8 room btw, and i have no problem with heat- just run co2 and a temp/humidity control box.

exactly my point. it is perfect to cool nutrient but you got to have the ac.... your chiller would not shut off if you added an inline fan on an evap coil of any kind.. not while the fan was on anyway. maybe in lights off then you are adding a ton of heat during lights on. i dont think u realize how much heat the chiller can produce when left on for a 12 hr cycle....

u need a super sized chiller and res to efficiently use chiller with cooling the room. a water cooled grow room has no ac unit. it has a chiller..

number one, water cooling doesn't add any humididty, in fact if anything it would act as a DEhumidifier and precipitate any moisture in the air out on the cold lines.

number two, why would you expect a water cooling system to cool a whole room? they're designed to cool small spots , they need several feet of line to radiate the heat from one res, one computer chip, one c.o.b. chip...get an ac to cool the room, thats what they're designed for, use a water cooling system to cool a specific thing in that room...

Call me crazy but I think are using the chiller wrong. While they do make air cooler attachments for 6in venting that have copper piping in them for chillers which you can use to cool cooltubed lighting you'd be getting pretty redundant bringing in cool air from a portable AC along with using that to cool the air as well. Those chillers are primarily meant for cooling water in hydro setups where the heat output is negligible compared to the AC cooling the tent/room as to concentrate the low temps specifically to the water which you want at least good 10 degrees lower than your canopy temps. As for humidity, AC lowers humidity during operation so as long as your AC is sized appropriately you should see a reduction in humidity. Also, I don't believe there is any quantity of light where co2 wouldn't benefit if done right.

Im water cooling my 5x5 tent with an 8in ice box from hydro innovation and a 1/2hp chillerand 25gal Rez. Cooling about 1000w of LEDs and a 50pint dehumidifier. Works better for me than ac because I’m running co2, so a 20lb tank lasts me quite awhile now. I live in a dry 32% humidity area and water cooling gets me up to about 50-80% depending on plant stage. Only need the dehuy during flower. And that’s with the ice box located outside my tent as well

Curious about your exact setup with ice box. PM'd you also though.

I cool my room exactly that way using a chiller and a res and two 8" ice boxes. It's 2 1/2' wide x 11' long. It's sealed with co2 generator I also cool and a 30 pint dehumidifier.

Woah, cool man. I'd like to see pics, if you can. If not, no probs.

I'm not a picture guy I'm sorry. Heldover fear from prohibition era, and still not sure we're out of the woods with our personal freedoms anyway. That being said the water circulates through the chiller, reseroir, the ice boxes, and the co2 burner then back into the reservoir with one 8" inline fan blowing room air through the iceboxes. Since I use co2 I want the room over 85 anyway, I use LED, and lights on is at night. It works. It worked great when I had a 1 hp chiller but I use a smaller one now, and it's not ideal. This summer was too hot for it a few times and it didn't keep up. It did with a properly sized chiller. Sentinel environment controller runs the fan, dehuey, and co2. Next summer I may shut down until fall but I don't know. I'm moving my led drivers for one light out of the room so that will remove some heat. Stealth was key for me choosing water cooling. No outside condensor unit like with a/c. And I put it together myself without an a/c tech. Several years ago. There are diy a/c options now I would think about maybe but not certain. Water cooling has advantages for sure. It's underrated for small setups but large scale architecture is often water cooled.

I understand, and I agree completely. "Legalization" is a term used for governments and corporations, etc., so they can setup and operate "legally". Dumb dumbs filled their minds (lots of space in there) with delusions of what the term would mean.
Anyways, that sounds pretty sweet man. The room I was helping to setup has some similar design, led, co2, not wanting to have condenser on the outside, etc. I considered building an ac box for the condenser and running outside air to and from it via insulated duct. But other shit has come up and it's all on hold for bit.

Can I ask how many watts, both of led/drivers, and total (the btu budget so to speak) this setup is handling, and the general size of the room? 10x10x8ish, 5x5x8ish, 12x20x12ish? Haha.

Oh and how is the co2 generator cooled, not directly, right? Unless... you're using a "minigen" or a "hot water on demand" setup or something?

Thanks.
Edit: slight re-wording.

I have a narrow space 31" wide that is about 1 1' long and 9' high. 700 cob led watts and 30 pt per day dehuey. I did all the math over and over before I set it up. All based on 1 hp eco plus commercial chiller 10500 btu and 50 gal res. I don't member the room btu but I got the bt u info from the ice box company. Worked like a dream but had to give the chiller back and a new one is about $1000. I made a manifold for water lines to go to each cooled device (2 iceboxes, co2_burner, and a spare i planned to use to cool my dehuey. ) now it's so different and I'll explain it when it's just right. It's close like I said and it works be fine from now until mid july. But moving my drivers wil help.

Very cool, man. Look forward to hearing about your 'improvements' and stuff. Still not sure how individual devices are directly cooled, if that's what's going on.
Sounds nice though. Thanks.
