DWC, learning too fast. Water too hot on dwc. chiller ideas

It's winter now and I have a 3 foot crawl space, I put my air under the home. Also I meant on my last suggestion, use dry ice in a old fridge and put air pump and dry ice into fridge

1. Air tube
   Dorm refrigerator
   or basement or outdoor area that's col
   Open fridge
   Drill pencil sized hole
   Place pump in fridge
   Pump cold air I. To dwc
   BETTER way
   Wrap tube around pipe inside fridge. Coil hose around cold pipe
   BESTWAY
   CRACK CO2 in fridge, pump cold co2 into bucket
   You get there are lots of variations too this
   But if you go dwc, you need digital shat, ph, ec etc. you also need to be smart and micromanage. Yet never adjust abruptly at ALL

Try freezing some water bottles and put them in your main bucket. You want to chill the roots. But i heard dont go under 57 degrees farenheit. Not an expert but hope it helps

Increase your reservoir size would proly be the easiest, uncomplicated thing to do.

igloo coolers.

Thats legit. I like it.
[h=1]Coleman 40-Quart PowerChill Hot/Cold Thermoelectric Cooler[/h]Something like this you could plug in. Not sure how good it would be running long term.

I've put a few together for this or that. Here's one with chiller.
I've built small ones for cloning and multi-site ones for start to finish.

No need for that. I freeze RO in tupperware and pop it out like a big ice cube, if no constant water pump is involved it will hold temp for days.

You hydro guys come up with some of the most inventive shit ever. Very bad ass. Not for me. But cool none the less.

There's actually a cooler club here on the forums somewhere, I joined and never do visit for some reason. More than one person does single site team water jugs in rdwc which is what I think I'll start next .

single site team water jugs in rdwc.
sure, whatever that is lol.

what kind of pump? you should try and put it on a timer first. on for 30 mins off for 30 mins see if that drops the temp any. cheapest way first
