radio shack didnt have it i checked there first , i ended up just splicing the cables

I was thinking of making one of these but just to place on my intake for the room. I already have cooltubes with lots of fans but i still can not get the temps down since the rooms in the middle of the house. Was going to make the copper tubing around the fan but i think this is a better method. The house temps are always above 78 so in the room its always above 80 with no lights on, so no reason to turn the lights on since its just going to get hotter. Well this is holding me up cant move forward tell i figure out a solution to this problem, i wish i could just pull fresh air in there would solve all the problems but that means more holes and more ways to get noticed. Just seeing any feed back on the people that have built one and are using them how are they working, any problems to think of while building one, do you think it will help cool the room 2wx6Lx7h, ?? Thanks for any help and feedback.

biggest thing i ran into was that you still need a chiller to use this effectivy. theres alot of diy chillers but they are ugly and take up alot of space. i figgure a chiller is about 400$ this cost me about 50$ and then the pump and comes out to about 600$ and this isnt bad considering it would take care of alot of heat problems for alot cheaper than a portable ac. but i started to think for about 600-700$ i could buy an led panel and hot have to worry about it.

The DIY chiller made from a water cooler looks promising, you can get one for less than $50 on craigslist in my area.

Alright i have been thinking of different ways of cooling my room,

right now with the temps 70 -90(outside) the grow room gets 74-78 with lights off and i have been testing the lights, with lights on it goes up about 10 degrees in the room with the cooltube setup. So thinking that in the summer the outside temps are 85-100 the rooms going to get really hot.

I don't really want to go buy a chiller for this small room and i already went through a few portable ac's so i don't really want to spend 150 or more

So getting idea from all these threads i was thinking of doing something like this.

10' - 3/8 flex copper - buy $15
6' - 3/8 freezer tubing - buy $ 10
pump - already have one
normal Tupperware would work for this - already have allot
mini fridge - already have one

Using the copper i will make the spiral for around the 6'' intake fan opening, then hook that up to the freezer tubing, that runs into the fridge to the pump, in the Tupperware with ice and water ........

..... the fridge should keep the water cold so i do not have to replace the water and add ice all the time. Only thing i do not know is if the pump will work in the cold water in the fridge!!! any one know ???

Trying not to waste time or money but sometimes trial and error is the only way.

Thanks for any input or ideas i am all ears.

Here's my DIY chiller made for 100 bucks from a wal mart window ac. Pulls this 100 gallons down w/ 1k hps fresca to 65f no problem. It can actually freeze the top layer of water. I think I could do 4 1 ks in the winter and 2 or 3 in the summer. Could also get a bigger ac unit for more.

Nice link thanks!
I should point out though if anybody is going to make something like this, that if you are going to use it to cool your hydro reservoir also, to make sure no copper comes in contact with the nutrient solution, it can kill plants.

That's correct. I just pump the cold water through tubing in the hydro rez and back. Going to get a piece of titanium for this soon.
This system works great. Mines been running flawlesly for almost a year. Couldn't afford a commercial chiller, plus the reef tank chillers everyone is selling just doesn't seem up to the task. If mine fails a quick trip to walmart and 100 bucks and I'm whole again.

Love your ice box. Going to have to try this. I may cool my room this way as well. You should be able to capture the condensation, re-use it. it's distilled water.

The water out of my dehumidifier is 0 ppm 6.2 ph.

I plan on putting it in a small plastic tote with a drain line, just have to many other things cooking right now but when I get around to it I will post it.
