Copper in res is bad. You need the copper in it's own tank of water chilling that. Then a pump running the cold water threw SS tube in res wort.
For sure man, glad we made it through all that hahah. I like having these types discussions as I'm here to learn just as much as anyone else. But I dont feel I've learned anything if I'm too busy arguing and defending to really want to hear the other persons points and counter or improve upon them. Its hard not to get personal even though we're only disagreeing about mostly technical things, not moral or opinionated. And I think by the time we're having these kinds of debates we've gotten beyond the basics, which is what 99% of the forum is.Seems that the best method for harnessing the power of warmth for root growth without becoming overrun with bacteria would be aeroponics. I run flood and drain buckets so even though my REZ temp is 66F, my average ROOT ZONE temp would be closer to the ambient temp of the room (74F) which does give the roots some warmth. However, I still believe that a cool REZ is the way to go. Airstones and waterfalls are great if you have bubbles in direct contact with roots OR if your water is cold enough to absorb DO. Thanks for the in depth responses Mike, you make some valid points and seem to have alot to offer. Oh, and what do you think about replacing the 5 gallon bucket on your chiller setup with an igloo cooler for efficiency?
Actually I have never seen a SS heat exchanger on any geo heat pumps I have installed, always coopernickle or copper. I would think that is due to cost and the conductivity. I probably will use a closed loop attached to tube in tube exchanger. But just imagine all the stuff leaching out of all the plastic used in hydro under those bright lights......lol.You can utilize a stainless steel coil on geothermal systems.
I have no doubt what you say is true being acidic, but with all the different opinions on this and other sites I typically do a bit of reading before deciding what is best for my particular setup. No offence!!! Just look around and you'll find 100 different responses to a question....lol........ I was totally fucking confused when started to dwell into the world of hydro....LOL..... I took the answer that seemed to be the most consistent and then read some more!! As my plants are doing OK I guess I picked the right ones...... I hope.......I'll let you know in about 5 weeksno need to really research it bud, passing nutrient solution at the proper PH for growing will leach copper into the solution and your plants will die.
This should be deleted as it is such bad advice telling ppl 86 is where it should be and less is bad. 86 is only for seedlings. When they are ready for dwc I'd say anything above 74 would give u problems in the rootzone. Please read carefully and don't listen to advice like this without researchI think you meant 86. If your res is any cooler, you're getting less than optimal growth. With the benefit of not having bacteria outbreaks every other day of course, but still not optimal growth.

What problems are you talking about getting in the rootzone there PotHead? Bacteria-related, am I right? Ok, now re-read the second half of the post you quoted. Then read everything I said from that point on. Feeling pretty stupid huhThis should be deleted as it is such bad advice telling ppl 86 is where it should be and less is bad. 86 is only for seedlings.

Personally I wouldn't want my res temps to go above 70
This right here!!!!!!!!66-70F + airstones + DM Zone + moderate ppm = Thriving roots.
This is as simple as I can make it for you guys that are still having problems. It's a 4 step recipe for success for crying out loud, use it. I would use the term "foolproof" to describe this method but I know fools who can screw ANYTHING up.
How was everyone's Halloween? My gf and I passed out candy to the little monsters in the rain, I miss being a kid.......
I never had to do any of that.. you can easily keep your reservoir cool by adding frozen water bottles daily. Hydroponics isnt for the lazy grower..Just a thought, I'm dealing with the same issue. How to cool my reservoir in dwc? Has anyone tried this? I'm considering getting one of those 1.7ft dorm room type fridges and putting my air pumps in there, that way the air pumps are always pumping cool air into the reservoir. Any thoughts on my idea? Any possible issues I might run into with it? Looking for feedback b4 I drop another $50 on one of those fridgerators.
