Look what I found out, can I use it to cool my room temp?

The only reason I built a RCWC system is because i believed I needed 13 gallons of nutes to run a chiller (I didn't even know what RDWC was when I was building this thing I should have looked up more before starting hydro).
Anyways that is not true, it's very FALSE and this can save you a shit ton of money if you use expensive nutrients like me or just save you distilled water and nutes because you can cool tap water or any other source you want this way. And you don't have to use the minimum amount of nutrients required for your chiller (Idk why it's 13 gallons but I like to follow instructions on expensive equipment).
It uses a larger container (27 gallon tote in the pic) that you cool tap water in. Then you suspend your 5 gallon DWC bucket in that cold water and the temps should balance out after some time and that bucket filled with nutes will become equal temperature.

I WANT TO KNOW

Can I use this cold tap water to cool my room somehow, I was thinking about ordering some sort of sprayer head attached to a pump and spraying it in the air. Or maybe running this water thru copper pipes or something and blowing air over them.
I don't really know about cooling units or how they are made. But I want to know if this wate can also be used to cool the air in my environment. Any ideas are appreciated I would like to save money on an AC unit. It's my next needed purchase. I've been pushing it off quite some time

Thanks

Sup @MedicalMike420 . Yeah dude you can use that water to cool the fuck out of your nutes and your room! Make sure you are not on metered water though, or you'll pay out the ass for all the water you're gonna use.

Cool your room by buying one or two cool boxes http://www.amazon.com/gp/product/B002JLAC3I?psc=1&redirect=true&ref_=ox_sc_sfl_title_2&smid=ATVPDKIKX0DER
Buy a cheap thermostat like this one http://www.amazon.com/gp/product/B011296704?psc=1&redirect=true&ref_=oh_aui_search_detailpage
connect an inline fan to a the cool box, connect the fan to the thermostat, connect your cold water to your cool boxes connect another tube to the out end of the cool box and run that tube to a drain. Then just run your cold water while your lights are on.

You'd just set the thermostat to turn on the fan connected to the cool box at your desired temp. This would blow air past the cold coils in the cool box(es) and should be able to very efficiently and effectively cool your room.

You could go one step further and buy a sprinkler servo like this one that I use in my chiller and connect that to the cold water, and plug the servo into your light timer. That way the water would flow automatically when the lights are on.

If you do this let me know how it works. I am going to be setting up something similar with 4 to 8 cool boxes cooling my room and 4k watts of light.

Sure thing bro. Here is the link, https://www.rollitup.org/t/aero-nft-grow-in-tent-w-co2-ac-dehumidifier-and-diy-chiller.899872/ and I am also pasting the post with the instructions here. But if you have time please do browse through my thread and let me know what you think.

I have access to a fresh cold water faucet in my grow area and a drain. If you have these in your area try this out. It works absolutely great.
This was my #1 concern, keeping my reservoirs cool. I researched, then researched, then researched some more.

The idea of a traditional chiller was too expensive and pretty inefficient, and pumping my nute solution to a remote chiller seems fucking retarded (how to keep the lines from getting dirty, potential for flooding, extra reservoirs, fuck that business). Peltier Thermoelectric chillers simply would not do good enough, they are expensive to buy, annoying to make, and quick to fail. So what were my other options? I was stumped!

I went back to the drawing board and designed my own reservoir chilling system. Full disclosure, I am positive that other growers have developed the same chilling system as I did, but I could not find shit about it on the web so I designed this one all on my own. I am not claiming to have invented style of chiller, but I am fucking stoked on it and would love to hear from anyone who has done anything similar. My first designs were very similar to other DIY chillers out there and there was nothing special about it really. My first plan was to put put a coil of hose in a fridge and pump my nute solution through it using a timer. It would have worked, but also would have used unnecessary electricity and added extra headaches.

Frustrated, I then remembered that I had used a little thingy called a wort chiller when brewing beer in the past. Basically this is a immersion chiller that consists of a coil of metal tubing (usually copper, but you want a stainless steel one to prevent any leaching from the copper caused by the nute solution). What a great way to go! This meant I wouldn't have to keep any extra pumps in my res and I never have to move the nute solution out of the res to chill it! Duh, tons of people are using these so I don't know how I missed it!

I set out to put a really big res filled with potable RV/marine antifreeze into a freezer, then put a pump in the res connected to a hose that pumps the antifreeze through the wort chillers that sit in my reservoirs. The pump would be turned on and off by the another one of these $38 Inkbird thermostats with sensor and outlets built in.

Right when I was about to buy a fridge I had little light bulb go off in my head! Why the fuck should I wast time, power, and money on a fridge when my tap water is 43 degrees once it runs for a minute or two? I was stoked! I had finally figured it out!!! I am lucky enough to have a drain in the floor of my grow area and I plumbed cold water faucet to the area as well. Without both of these, you will not be able to run this chiller, sorry.

I turned my attention from fridges to sprinkler valve electronic relays. They are cheap and they last forever! Here is how it ended up working out. Don't buy cheap hose parts though because THEY WILL LEAK! I was able to build my chiller for my 2 flower room reservoirs for about $210 and its really easy to build. Shit is extra expensive where I live, so you can probably do better. I will do a detailed thread with pics and instructions on how to build this chiller as soon as I have some down time, but here are the basics.

These items work for my set up. You may need slightly different lengths of tubing, hose and more or less of some items. Measure and plan before you buy!

Supplies For 2 Reservoirs:

1 cold water hose faucet (sink will work but you'll need a garden hose adapter)
1 drain
2 - Super Efficient 3/8" x 25' Stainless Steel Wort Chiller = $40 each (brew shop or Amazon)
1 - Inkbird Itc-308 Digital Temperature Controller Outlet Thermostat, 2-stage = $38 (Amazon
1 - Orbit 57100 3/4-Inch Female Pipe Threaded Auto Inline Sprinkler Valve = $12 (Amazon)
1 - Orbit Sprinkler System Power Source Transformer 57040 = $13 (Amazon)
1 - box of miscellaneous wire connectors = $5
2 - male 3/4 threaded to male garden hose adapters = $5 each (Lowe’s)
2 - 2 Way Solid Y Valve Garden Hose Connector Splitter Adapter = $13 each (Lowe’s)
1 - PTFE Pipe Thread Seal Tape = $2 (Lowe’s)
1 - 50’ length of garden hose = $13 (Lowe’s)
6 male and 6 female (this should be enough to have extras) hose repair pieces = $5 each (Lowe’s)
1 - 20’ length of 3/8” vinyl tubing = $10 (Lowe’s)
1 - 3/8” vinyl tubing T = $3 (Lowe’s)

Instructions For One Reservoir: (If only chilling one res you will only need 1 wort chiller and you wont need the vinyl tubing T.)

1. Connect 2 Way Y Valve Garden Hose Adapter to water faucet.
2. Connect one side to the new garden hose and the other side to your old garden hose (if you have one).
3. Run the hose close to your flower room and cut it to an appropriate length (pvc pipe cutters work great for this).
4. Connect female hose repair piece to the end of the hose where you just cut it.
5. Connect the 2 male 3/4 threaded to male garden hose adapters to the Orbit 57100 3/4-Inch Female Pipe Threaded Auto Inline Sprinkler Valve using PTFE Pipe Thread Seal Tape and be sure to tighten well using crescent wrench.
6. Connect the hose to the Orbit 57100 and tighten well. Be sure to find the arrow to ensure the water goes in the correct hole and out her other.
7. Connect Orbit Sprinkler System Power Source Transformer 57040 to Orbit 57100 using wire crimpers and connectors.
8. Connect another female hose repair piece to the other cut off end of the hose.
9. Connect the hose to the out end of the Orbit 57100 and tighten well.
10. Clean the wort chiller using dish soap to remove any machining oils and rinse well.
11. Insert wort chiller into reservoir.
12. Connect wort chiller to the garden hose.
13. Connect vinyl tubing to other end of the wort chiller.
14. Run vinyl tubing to drain.
15. Connect Power Source Transformer to the cooling outlet on the Inkbird Itc-308 Digital Temperature Controller Outlet Thermostat.
16. Put temp sensor in the reservoir.
17. Plug thermostat into outlet and set desired temp, dead band, alarms, etc. Calibrate the unit if necessary.

Instructions For Two Reservoirs:

1. Follow instructions 1 through 9 from above then the following
2. Run the garden hose to a central location between the two res and cut.
3. Connect male hose repair piece to the newly cut end.
4. Clean the wort chillers using dish soap to remove any machining oils and rinse well.
5. Insert wort chillers into reservoirs.
6. Connect vinyl tubing to the supplied garden hose adapter.
7. Run tubing to the wort chiller and cut to appropriate length.
8. Repeat steps 6 and 7 to the other wort chiller.
9. Connect vinyl tubing to both wort chillers using supplied clamps.
10. Connect separate vinyl tubing pieces to the other end of each wort chiller.
11. Run the end of the tubing to a point where you can connect them to the vinyl tubing T.
12. Connect another piece of tubing to the other end of the T and run the tubing to the drain.

I set my res temp to 67 degrees with a 1 degree dead band so that the second the res it gets above 68 degrees the sprinkler relay is activated and cold water starts flowing through my wort chillers and thus chilling my nute solution. As soon as the temp goes below 67 degrees the water ceases to flow. I keep my sensor in my warmer of the two reservoirs and they stay within 1 degree of each other. I could adjust the flow to each res using the valves on the y adapter to get the temps exactly the same if I wanted, but I just keep the valves wide open cause I am not worried about the 1 degree difference. Make sure to secure the vinyl tubing into the drain in some way. If you don't the line has a tendency to pop out of the drain and start spraying water everywhere.

Orbit 57100 3/4-Inch Female Pipe Threaded Auto Inline Sprinkler Valve (sprinkler relay)

I have it housed in a bucket just so its out of the way and doesn't get kicked accidentally.

I don't have any pics of the wort chillers, but they are pretty straight forward. Let me know what you think about this and would love to hear about other's experience with similar set ups.
