    Cooling question

    What would anyone recommend for a cooling system for an AP system in a green house where space is limited and at a premium (read: SMALL)?

    Central PA area. So, temperate, I guess?

    It's a small 6X8 polycarbonate greenhouse. Have a 3X4X1 media bed with an external sump and the fish tank partially snak into the ground about 8 inches...

    for cooling you'll need air flow through the gh, for a cheap solution, you could use a diy swamp cooler if your humidity isn't too high..
    your gb will act as a heat sink, insulate if you can, or cover with something reflective..
    running a chiller would get pretty expensive.. when it got real hot here during my first season, i froze milkjugs full of water and used them in the ft... i had 4 or 5 1gallon jugs that i would rotate out during the day

    I was almost thinking of somehow running some of the water through some copper tubing as a heat exchanger... But, I lack that technical know-how...

    I have heard of a cooling method that sinks aluminum stakes deep into the ground and comes up around and into the sump tank. This acts as a type of heat sink. The deeper the stakes into the ground cools them and transfers that to the sump....

    Be careful using the cooper tubing to directly run your AP water through, as some of the metals can leach into the water and harm your fish in some cases. For a small system such as yours I would think about digging a deep hole outside your greenhouse and burying a coil or so of Pex pipe, then either circulating your AP water or a portion of it through there, or preferably use clean water in a closed loop with a separate pump, connected to another coil in a sump with your AP water and use it like a heat exchanger.
    Never show your ignorance, by thinking you know it all
