    I would assume cooling capacity would be related to volume of air, temp, RH, surface area and to some degree velocity..:

    Took my first official measurements, still on the first batch of solution. I mixed it up without the benefit of measuring the pH and EC

    2-9-16
    Test unit 1 solution

    pH 6.9
    EC 460 uS/cm
    Temp 62.5f

    Very pleased with growth so I think I will lower my target levels to 400-600 uS/cm

    😊

    Think I need to reduce my target pH as well,

    New target 5.2 - 6.0

    Made fresh solution

    Baseline
    pH 4.8 (no additional buffering used)
    EC 550 uS/cm
    Temp 57.5f
    (started with RO water @ 22uS/cm)

    Expect pH to rise and EC to drop as nutrients are used up.

    Definitely, but starting out with air which you compressed, generating heat which dissipated away and the re-expanding that air is a win/win thermodynamically speaking, particularly if you allow the heat generated by compressing the air to dissipate someplace you actually want heat.
    Judge not lest ye be judged creates a cesspool. Judge others and prepare to be judged by them.
    Just know when to keep the verdict to yourself.

    You know, they can treat that with diet and injections . . .

    Document it and send it to the The Daily Mail, so it can be enjoyed with footage of explosive boil-lancing. What are you thinking?
