Water chiller 4 flower/veg resv?

I'm having problems with my res being too hot I'm pretty sure! I'm keeping ten gallons of water in my reservoir(Rubbermaid tote). The plants look super healthy green, bushy growing well. My res Temps are at 80. They have been lower lately but I just dropped my 4 foot 8bulb t5 down real close to the plants last night and they shot up.
Im looking to buy a chiller, but my problem is that pretty soon I will have three separate reservoirs with three different mixes of nutrients in them. I will have a perpetual grow with all auto flowers. So I'll have one tote with no nutes, one with veg nutes and one with flowering nutes..
My question is.. How do I go about chilling these three?! Without buying more than one chiller. The ones I've seen you have to cycle the water through them.. This is not an option if all your water is different!
Thanks for any help in advance.

Hi. It could be done with differents ways.

1. Cold water res, 3 ss coil and 4 water pums. Each res have its own cooling loops. The chiller cools cold water res.

2. Using chiller, one pump and manifold with 3 valve( one valve for each coil. Those are using for set water flow for individual coil)

For my water cooling system I'm going to use this http://p.alejka.pl/i2/p_new/07/40/rozdzielacz-podlogowy-3-sekcje_0_b.jpg . It has flow meter for each loop and works with thermoelectric servos.

Trying to see about going more this route.. It's just an idea though. It's expensive, but the way I look at it, it's worth it if it works good.

After reviewing some things I think I'm better off going with your first option. I could have a chiller cooling a reservoir, and from there have one pump pushing the cold water through tubes in the other three.. Pvc-maybe something else?
I didn't think of that before you said something! So thank you

I have a cold water reservoir, one pump and a manifold to send water where it needs to go for cooling. The lines are all just normal half inch. They cool my res and climate control my space, both temp and dehuey. Doing it this way is easier and more efficient than AC.

For those who insist on getting toy chillers (anything under one hp), at least keep the thing away from walls and outside the growroom.

I still be buying a 1hp. I'd like to find one with an external vent so I can vent it outside since the grow space is a camper. I've got a good job and excess $ at the time so I look at everything I buy for the grow room as an investment.

Ttystikk- your chilled pvc- do you just go into your nutrient reservoirs and have the lines running through them, recycled back to your chilled res?

I'm thinking of putting two half inch holes in my totes at the bottom so that I can run the pvc into, and out of each one. I will make a U shape in the res for more length of chilled pipe being underwater. I am About to research some more when I get home from work and order a chiller.
Any recommendations are appreciated!

I would like to keep energy efficiency in mind but don't want to sacrifice performance for it.


*after looking at then it looks like im probably better off buying one of those toy chillers, half HP maybe, only because I'm only trying to chill about 15-20 gallons of water at a time.

It depends on how you'll be cooling the rest of your op. I use mine for environmental control as well as water cooling duties. In this way, it replaces other AC systems. One of its biggest advantages is the ability to place the chiller far away from the grow and just run a pair of waterlines to it. This means you can stick it out the window, place it outdoors, in a ventilated garage, whatever. It ALSO means that in the winter, you can place it in your house and use the heat you've already bought once a second time to heat your home. At no additional cost.

LOL at the comment implying that efficiency is the enemy of performance. Nothing could be further from the truth!

Think about this for a moment; four Tons of chilling can and does cool a whole 24kW op, counting what's on the flip. And you should count what's on the flip, because whether your AC unit runs or not, it's still a sunk cost.

I plan on keeping my window ac. I keep it on all the time with a 4 inch inline turbine type fan coming funneled off of it Pushing air to the back of the camper where the lights are.
This keeps the Temps in the room around 75-80 but the reservoir stays the same..
I will keep the chiller outside of the grow and runs lines like you said, this seems like the best way!
With these type of chillers, will I get colder Temps on a 20 gal res with a 1 hp chiller than I would with a half? Also you said that you use it for environmental control instead of using an ac? Could you please explain this to me somewhat

One hp is a capacity rating, so it will remove twice as much heat from the water as a half horsepower unit. I recommend using a cold water reservoir because it makes the chiller system easier to set up. For what you want, ten to twenty gallons should be plenty.

For environmental control, I pass cold water from the chilling system through a radiator. This radiator hangs in the growroom where a fan blows air through it. It will cool the air and if the water in your chilling system is kept cold enough, it will dehumidify as well. You can think of it as a minisplit that uses water as the working fluid. In this case, the Freon stays inside the chiller and you just route waterlines.

I love your idea for cooling the air! I ended up purchasing one yesterday, it should be here by Tuesday.
I'm not exactly sure what size pump I'll need yet but I've got a few laying around varying in size. I'm really going this cures my little root slime type problem I got Goin on. They're not Growing like they should be that's forsure. Still healthy, but stunted.
Thank you guys for all the help

LOL it's not MY idea, people have been using water to heat n cool for decades! In fact, it's standard procedure in skyscrapers and places with tight ceilings or little room. I just know a good idea when I see one.

Very very "cool" idea

What kind of radiator did you use?

Mid '80s Volvo, from a local wrecking yard. I chose it because its fan shroud was a near exact fit for my circulation fans.

Turns out that's not the greatest match of fan and load, so in future I'd recommend a single row aluminum radiator from a Japanese compact car. These should be plentiful and cheap. Squirrelcage blowers are the preferred method of shoving air through them.

In winter, it's highly effective to set one of these up outside, with the fan SUCKING air through the radiator this time. At freezing temperatures, mine was good for well over two Tons of cooling!

This water cooling stuff scales in ways AC does not. I also believe it has applications even beyond what it's currently used for.

Indoor gardening is here to stay, and the new name of the game is efficiency, or getting the job done for less watts.

Think if it this way; If there are opportunities to actively move heat from place to place that directly displace having to spend money to do the same job, why wouldn't you do it?

Very intriguing
Thanks for the info

Hope you have good luck with that active aqua. I didn't.

I like my jbj arctica.

I have had great luck with my chiller actually! The other day I lost power to my entire cooling system (a/c, fans, water chiller) but not my lights. It had to have been 100 degrees in there when I got home and got it turned back on. The temp on the display on the chiller was 92 and within 30 minutes it had my 15 gallons back down to 65!

The other part I was worried about when I bought it was the heat output. It didn't make much of a temp difference at all as I have a window unit in the room.
