Cheapest diy water chiller?

What I'm thinking is run a water line from my reservoirs to a pump that pumps my water outside to a stainless steel wort chiller that is buried a couple feet underground. As long as no light is getting to the water is there any reason that wouldn't work? Stainless should hold up underground?

SS doesnt hold up underground without cathodic protection.

type 316 does better than 304 but they will all corrode and leak.

Or you could look for a chiller on craigslist. Otherwise, I agree, the 316 does better than the 304. (I have no idea what that is, lol @firsttimeARE )

Grades of stainless.

304, 304L, 316 and 316L. L is low carbon I believe.

Either way I wouldnt bury it unprotected.

Bottle of water freeze it put it in the res.

Wow i just learned something, i thought stainless steel didnt rust or corrode

You want to learn something else? All cold water in a res does is raise the level of oxygen available to the root system. Roots don't need cold water (warm is fine), what they need to thrive is good old oxygen, and a lot of it.. Air stone the shit out your bucket or res, done deal. Been there done that, and wasted a lot of cash on a chiller. Save the effort.

Uhm no.

Cold water reduces the likely hood of pathogens growing in your water.

Colder water does increase DO. Its not hard to maximize DO though. I get root issues with warm water and plenty of air. Same air and 64F water and im fine.

If you're into DIY you could make a simple chiller like this one here. I would, but my girlfriend would slap the absolute shit out of me if I destroyed her chiller.

I've also been playing around a bit and stuck my air pump into this mini chiller and just put some ice packs inside...

My theory is that the cold air from the ice packs will be sucked into the reservoir... and the chiller acts as an insulation (that's what it's built for)...

So for nothing, but I might just add some more ice bottles, ice packs, ice etc.

Or my ex girlfriends heart, that bitch had a cold one.

I was having same issue. I Just got my grow area temperature colder at 25 celsius then the water fallow .
