Cooling Rez tank with cold air?

[CANNACO-OP]

Could you:

take your regular fridge that is allready running (rather than add another or getting a little mini fridge) or getting an old mini fridge. Anyways, drill a hole through the top/side or what not, put an air pump inside the fridge, run your air hose from the fridge to the res/water or even your little pc grow/'mini grow/small closet, seal us the hole w/some silicon, maybe use timer.

blow some cold air into your problem......



whatta think?

You would have to have air entering the fridge if you want cold air to come out of the fridge.
I don't know that it could keep up...

I've tried cooling my res using a small heat exchanger (a vehicle transmission cooler, actually), strapped to the front of a 9K btu air conditioner, on 24X7 with a pump to the res.

Didn't hardly do shit to water temps. I imagine your cold air on the air pump would do less than that, sorry bro, but keep that engineering spirit alive!

On that note, I did stick an air pump in a box with a small ozone generator, that worked pretty well at oxygenating the reservoir with O3, and killed off my pythium eventually, but it ate water pumps as o3 is corrosive and eats rubber seals.

put your res inside the fridge....

take the fridge apart and put the cooling element inside the rez.

put 2 holes in the fridge and run put alot of pipe inside (in coils) and run your res water threw it slow to cool it.


thats my three options... all will help a little some might help more then others.

Google, ICYBALL, and go for what you know.

It mainly depends on the gallons of water you trying to cool. You fridge idea how about putting copper wire in a spool like coil and place INSIDE the fridge and pump water from your rez through the coiled pipe and back in?

The idea of using air from a fan (I've even used a/c air right from the vent) frozen 2-liter bottles or even a heat exchanger will not hold a candle to a chiller for a 55 gallon barrel.

Used chillers can be had online at suckbay or you will find them listed on Aquarium sites in the forum pages (it's where I got mine 215.00 I think lol) for a song. These big aquarium guys are usually rich and gotta have the latest thing so get rid of non-wanted items cheap.

Bottom line, Yeah you might somehow McGuyver something that might lower your temps 3-5 degrees or so but If ya got a lot of water to keep cold a chiller will be the third best 300 investment in the future of your garden a grower could ever make.

Just what I needed to know......... diy attempts always considered.

i think the chiller is best idea and best bang for bucket and most control.

thought about small tank inside the fride itself, but seems like work for no reason.

i like getting the res tank away from lights and in dark area, mine stays 74 with no chiller.

this questions was for another co-oper, who thanks you all very much. we will keep ya posted as to results...

thanks again.

Peace, Canna

I believe if you put a tank of cold water in the fridge, then run your water through coils in the water it will cool somewhat effectively. I have read of this being done, but I can not tell you if it is worth doing.

when fixing a busted water line on my fridge i notice about 30-40 feet of coiled up water line that sat in the bottom of the fridge under the bottom drawer. i didnt know that there was that much or any in there. even if you were to double that amount of hose you could run it into the fridge and back out. i bet you could even set a timer to your pump so the water dosent get too cold... thats what i would do if i didnt want\coudnt spend the $$ on a $300 chiller. C ragislist always has dorm/ mini fridges on there.

I blow cold air at my ez-clone machines at the base not the plants.
