How much do one of them things cost? I'm sure I can do the conversion.Water cooler with water pumps inside, water temps stay at 69 degrees all day...let me kno if u need more info
Great idea Artie and I did something like that myself a couple years ago for my DWC tubs. Got an old cooler from my boss and had that kicking around for a while then came up with a plan. Took the guts out of the cooling tank so I could fill it with a coil of 3/8" tubing that circulates the nutes from the tub(s) or rez up to the tank and back to the rez using a small fountain pump. Covered the inlets of the pump with plastic window screen and used a hot glue gun to seal it in place to keep roots out. Works great and only cost me $14 for the pump as I had a big roll of tubing and got the cooler for free.Water cooler with water pumps inside, water temps stay at 69 degrees all day...let me kno if u need more info
Used on Craigslist or yard sale, $20- $40How much do one of them things cost? I'm sure I can do the conversion.
Thx old med...i basically use my chiller as a rez, i have a bigger pump in my dwc tote pumping into the chiller and a smaller pump pumping back into the tote, i adjusted both pumps to allow slow water movement, giving it time to chill, works perfect! PH, PPM AND TEMP levels stay the same in both "rez" and tote, no fluctuationOh yeah.
Insulation around the tub/bucket/rez helps with lo-tech chillers like this.
The white wall insulation is so much better for this use than the pink stuff if you can get it. A little baling wire and it's good to go.

Good to know. That was the route I was thinking of going. My res holds 18 gallons. But I also have a 5gal and 3 1/2 gal bucket. I'm gonna get a good one soon as I can but they are not the cheapest thing out there.Ive built a mini fridge chiller, I wouldn't recommend it unless your chilling a small quantity of water...under 30 gal. Mine ran so hot it discoloured the paint on the fridge. I was chilling 35-40gals tops.
A small freezer would be a better idea. The mini fridge was about half the wattage of a 1/10hp chiller and was probably running non stop to achieve the 5-7 deg C I was getting...barely enough.View attachment 3812642
I started out with just a 50' coil of 1/2" tubing....didnt work very well. I then put the coil in 5gal bucket of water...better, but not enough. I then removed the ice box and put it in the bucket with the coil...not bad, but the fridge became a fire hazard IMO and I bought a real chiller.
Oh and the copper almost killed my plants...
Ive seen some videos on youtube were they convert a dehuey into a chiller. Ive heard of others on here doing it also but its involved if your not mechanically inclined.Good to know.

Copper is a no-no as the acidic nutes will leach lots of copper and eventually rot the tubing right out.Ive built a mini fridge chiller, I wouldn't recommend it unless your chilling a small quantity of water...under 30 gal.

The plants began to yellow out like I hadn't feed them in weeks. It stopped after I removed the diy chiller. Stainless steel coils would solve that problem but its expensive and difficult to bend into a coil. You could make one coil outta copper than get a SS wort chiller coil to put in the res and run the chiller closed loop. Lots of fucking around though for what its capable of.Copper is a no-no as the acidic nutes will leach lots of copper and eventually rot the tubing right out.
Almost killed isn't dead so I hope you enjoyed the smoke.
If you restrict the airflow thru the window shaker too much, it will freeze the evaporator coil.Well I was thinking of building something like a box. I have an old table I was thinking if I put walls up on the sides and put the AC unit in like when you stick it in the window. Then cut a hole in the top of the table size of my res and put it on bricks or something to hold it above where the air comes out. Do you think it could be a fire hazard maybe? Or any kind of bad fumes? I mean like, why does that one part stick out your window? Is it just cause of dripping water? Just looking for a quick fix till pay day
What gph pump are you using? Could you slow down the flow of the pump if it is adjustable to achieve colder temps? The slower the fluid moves through the coil, the stronger the cooling properties will be on the nute solution. If it is flowing too quick, it never gets a chance to cool the fluid or to keep the coil cold enough to be effective.Ive built a mini fridge chiller, I wouldn't recommend it unless your chilling a small quantity of water...under 30 gal.
