Plants are having a rough time!

I love your Under Current systems (own 3) and I love surnas chillers (own 2 large units) but there cool coils are awful and have leaked to to poor fittings even with multiple hose clams they will leak glycol into your system and kill everything. I have found a answer that fits perfectly into 13 gallon master bucket around the large bubbler. It can keep a 36 unit system cool all day and night without turning on the other nutrient inline chillers. Whats best its on amazon prime. you will still want the solenoid/temp probe kit to turn it on and off from Surna.
run cool 66f. and sterile screw bennies and tea---- clean with uc roots DOES WORK!!

This coil is plenty long but not too long, I assure you that this is what you should be promoting for larger 13 gallon+ systems on your site and the fittings are ribbed so you wont have any leaking issues. The surns coil has the connections under water on short stubs of straight tube. If your chiller pumps have pressure like mine they will leak. I lost countless thousands of dollars and hundreds of man hours trying to figure out WHY? everything was dying. Good luck

Thanks for that. I am just working out the kinks in the system I put together over the weekend using an outdoor cool and heat exchanger. My glycol is a closed loop and water side is open to create more water fall effect. This should all work in the cooler months (now) but will have to cool mechanically in warmer times. I'm cooling about 70 gallons at the moment and flow is what I'm adjusting now. I need bigger water pumps lol.

I'd be interested in seeing more of what you've done.

Well not sure I'm proud enough to show any one this lol. Being a refrigeration mechanic it's kind of embarrassing lol. The inside looks great, and yes I'll put up some pics but the outside is just a shit load of coiled copper behind the shed lol. But yes tty I'll get some pics up when I clean it up a bit. Still got all the shit lying on the floor I used to build it . It's hunting season here so been kinda busy taking the stepdaughter out (it's her first year). Hard to get in the room these days lol. Did you get your unit up and running?

I just use tin cans punched with holes for rock filters, they actually last two or three years. The plastic screening off the front of a speaker was used to do the last overflow I installed.

My heat pump is now cooling my op, still need to get the hot side circuit built and installed. I think you'd appreciate some of what I've been up to, especially in terms of getting more HVAC bang for less watts.

Let me know and I can give you a rundown if you're interested.

Meanwhile, I want to see your copper rat's nest heat exchanger- I built one out of a Mitsubishi Lancer radiator, a Volvo fan shroud and a hardware store box fan. The thing pulls almost three Tons when it's freezing outside! Even with all the fun stuff I'm planning to do with my excess heat (up to 8 Tons of it!), I may find myself making more than I need, and so this compressorless chiller could come in handy for reducing power consumption overnight;

Just picture a bunch of coiled copped laying against the shed and that's pretty accurate lol. That's quite the heat exchanger btw, impressed by the Magiverism lol.

That's 'MacGyver', there, mate- and no coincidence he's a Scot just like myself!

Yeah. Scrounge your local junkyard for an old car radiator and fan shroud, then rig up a box fan to suck air thru- best for cooling, you know. When it's cold, I just plug in the box fan. I NEVER shut off the flow of water. Helps a lot to keep the unit in the shade.

Lol, I knew I spelled it wrong but said fuck it lol. This new phone spells for me and it gets it wrong more than right. Being in the trade I have access to lots of coils and fans but the copper seems to be working now and simple to chain together. I'm maxed out on power so even another fan may cause a melt down. I will work on a small outdoor condenser over the winter so I can run a bit longer in spring but going to have to do a monster outdoor thing to pay for all the shit I bought this year lol. Back to the swamp and bugs..... Fuck!!!! What I have found running the low pressure sprayers is the root zone can get hot unless there running all the time due to ambient temps at 75 so perhaps I need to insulate the whole chamber and not just the top. Or I may just go back to the nft type deal I was running, the depth of water was adjustable but ran it quite deep at about 8" and had great luck. This spray thing not so much. Was gonna build the controller tonight, thinking three circuits to keep three res's going at once if needed. The chilled water is an open loop through the heat exchanger. I'll get some pics up soon .

My heat pump is really quite under stressed handling the cooling demands. I'm sure it will have even less trouble with heating.
