Check this stuff out, concentrate version. Good stuff ! You can spray the plants with the lights on and or put in your DWC res.

I was absolutely one of the anti-bennies-in-DWC folks until I ran this experiment. I didn't want to trust my entire crop with an experiment, so I did this. I honestly wouldn't have switched if I hadn't seen it for myself. It caused a complete 180 in my views on it.

So you ran buckets with and with out hydroguard and chilled versus unchilled?

My cooling coils were copper and they worked fine. My chiller has a separate water circuit which doesn't mix with nutrient water.

Same cooling system also fed water cooled air handlers, which cooled and dehumidified the growing space.

I even designed water cooled COB LED light fixtures and ran cold water through them, but that turned out to be a bridge too far; I actually had trouble keeping the room warm enough!

I've never had any good luck with water treatments in RDWC; either the water was chilled to 65 at least once a day or my roots died.

Are you still chilling the water now that your running a new setup tty? I'm about to switch to something else but torn between medialess and other systems, got a week to decide lol.

I'm not running anything right now, long story.

RDWC needs a chiller, other approaches may not.

IMHO foliar sprays are a complete waste of money.

That being said, if you cant fit another pump or if the inline chilling units are too much, prob chillers do work pretty well. Except, it would be hard to install them on the side of the bucket (need a flat wall). If your res is under 20 gallons, they should keep it below 70C. I just made a little low profile DWC system for a friend of mine with some spare parts I had lying around. I even put a nice manifold system but currently not needed. You can see the probe chiller in the center (yeah bad location lol). Water temp around 65C:

Is there a product that would be better then active aqua or penguin chiller. Penguin chillerseems to be the highest rated.

Atomizer suggested using an old, small chest freezer as a chiller. You can get them cheap used. Just hook it up to a cheap temp controller to turn on/off and put your buckets/rez inside. You can close off the top with a foam insulation lid. Wont work in every case, but possibly a cheap option for some.

Not really into cheap startup cost on a piece of gear like this. I care more about watt effeciency and durability, not to mention I’ll need 1/4 HP minimum.

check either aquacave.com or bulkreefsupply.com high end aquarium suppliers. get a titanium coil model and it will last forever and probably also be able to be serviced if anything ever goes wrong.

i started doing drain to waste and ditched my chiller completely. probably should put it on craigslist one day.

Yes you should, I looked for one for months up here, hard to find. And I would have switched last year to DTW but I built it and was damn well gonna use it lol. I’m gonna rig up a chilled water fan coil and use it to condition the room this year :).

I trolled CL for about a month and got a 1/4 horse that was nearly new for 180.
Before that, well...... I used a shitload of Orca and HG. The stuff did me right though.

I loved HD but it was banned for sale here. That’s what pushed me to a chiller.

I suggested using a freezer as a temperature controlled aeroponic root chamber, not a water chiller ;) With a freezer full of water I suspect the compressor`s internal thermal trip would kick in before it got to temperature ;)
