    Here you are sir.
    IMAG0042.jpg IMAG0043.jpg inline pump keeps water cooooool as can be. No residual heat sitting in the res. There's no chiller on this one, but it sits on concrete. Also, flooming. IMAG0045.jpg each bucket has a line. IMAG0046.jpg IMAG0048.jpg IMAG0052.jpg

    I don't see why you'd even risk it being an issue.... These buckets were frosting buckets from my local grocery store. They were white. I spray painted them black with that rustoleum stuff I told you about. Sanding is a bitch but I wish I'd done it. A sand BLASTER BOX would be SO NICE for something like this though.

    I would make your system light proof before you start anything in it. Prevent a shit show before it even happens, man. H2o2 is great. I used 29% for the first year. But as long as you keep your water COLD and DARK, things will run smoothly. I assure you that.

    All my greenhouse/outdoor YouTube home slices use white buckets.

    Every black outdoor bucket DWC I've seen comes with brittle leaves from plant heat exhaustion.

    To your satisfaction I've always used black buckets for indoor growing.

    Instead of chiller I could partially bury a 55 gallon plastic drum to cool the water. 6 ft under the soil is 50°F year round. So how deep is it 65°F? Airwalker? Bueler?

    Oh snap this is going OUTDOORS?! I see your reasoning then.

    Hm. I'm not really sure... I'd try 3ft?
    So you're just going to circulate the water down into the res and pump it back up or what?

    I'll post pics of the whole thing.
    It's half built and I took a lot of breaks for mid-build replanning.

    x10 buckets 4 gallon
    x10 buckets 2 gallon as netpots
    x2 totes 40 gallon reservoirs (60 gallons true together)
    It's a one-way flow, the water will just be flowing counterclockwise pumped from tote to tote.

    2 rows of 5 buckets connected at one end and a tote per row at other end.

    You'll see

    The underground reservoir idea is to replace a tote with buried drum.

    Pump would be at bottom of drum where it's cold. Return would be at ground level and would flow into the drum.

    I could just get a lot of tubing and bury it.

    Tote goes where the blue tub is
    Receiving tote goes where the green sprayer nozzle is next to the saw.

    Kelp brewing
