A DIY water chiller setup

I'm going to wrap the vinyl water coil around the copper coil inside of the refrigerator instead of just sitting in the frig. Best way I can think of... another way I'm throwing around in my head is to put the copper coil in a sealed bag or coat it with a thin layer of rubber sealant and put that directly into the res...any thoughts on that?

Anyone know the warmest temp you could run one of these fridges at? What about putting the reservoir inside the fridge? have your grow tub higher and let gravity run it out (I would put the fridge outside the room) and down into the mini fridge. Pump and small reservoir inside..Just an idea, what do you think? JR

Just an after thought, would it be too cold if it had to maintain 55 in the reservoir for the roots?

Youd want your res water temp at about 65-68 degrees F. How would you put a 50,80.100 gallon res in a mini fride as they are only about 3 feet tall or less and about 2 feet wide? res is way bigger then that

Just curious did you ever end up building this and using it? I'm curious as to your results.

I went out and bought a 1/4hp chiller yesterday as the summer heat was getting the best of me, was a lot more than I'd hoped to have spent but works really well.

yeah i built it and gave it to a buddy since i never have res temp issues.Works well for him keeps res in 60's for his 50 gallon res

Not everyone is retarded, Oh a 100 gallons will not fit in a mini fridge, now I know. lol JK

No I would have a small reservoir, 6 gallons, to run a small areo setup. Would 55 be too cold and shock the roots?
Thanks for the answers.

yeah you want the water in the res to be at 65-68 so it hits roots right around 70 F

putting a small res in the fride will give far greater control.

here is a pic i found about 12 months ago. works great. its used in an aquarium the aquarium glass cries with water it gets that cold.

anybody have any ideas on rigging up a submersible thermostat to switch a pump to circulate cooled water through coils? ive been thinking about it for a while, but i can't even find the type of thermostat i'd need, though i know they exist... i'm upgrading to a recirculating dwc grow and want to run a cooling coil through the main reservoir off of a mini-fridge similar to that pic above. anyone?

I saw a battery thermostat with a submersable probe at an online aquarium shop, don't ramber whitch one Hope this helps. father

Aluminum brass pipes! weiiiiiiiiiiiiii

madazz clean your mail box No PM. Had a question Hey brother any DIY on the aquarium chiller ? How much water does it handle ? Could i run my 55 g res's to it ?

Thanks a bunch, here's a joke i saw recently.........
