    1/9/18

    day 12 of flowering for the BB

    changed the res today, the pH was trending down and the EC increased a bit.

    aero res
    pH 5.8
    ppm 830
    temp 68f

    day 6 since sprouting for the grape ape

    cloner res
    pH 5.77
    ppm 330
    temp 72.4f
    ambient under the dome 79f 42%RH

    day 13 of flowering for the BB

    aero res
    pH 5.8
    ppm 820
    temp 68f

    water level is falling, pH is rising, EC is very slightly falling

    day 7 since sprouting for the grape ape

    cloner res
    pH 5.75
    ppm 330
    temp 72.4f

    took the dome off

    ambient
    37%RH little low, might put it back on till they have more leaves
    77f

    @SSGrower

    This is something I've been working on, put timlib in there in case you didn't have it.

    fixed some code in cozir.cpp,

    this works, and is no longer a blocking call:

    sometimes there can be a delay of 80-90ms, so we build in a little extra pad of 10 millis just to be safe. if the serial port becomes available or if 100ms time elapses the code continues,

    for (int i = 0; !sertwo->available() && i < 100; i++)
    {
    delay(1);
    }

    this is the old code, and is a blocking call:

    do {
    delay(1);
    } while(!sertwo->available());

    day 14 of flowering for the BB

    aero res
    pH 5.8
    ppm 740
    temp 68f

    I'll up the concentration later, added about 4 gallons of RO to the res

    water level is falling, EC is falling, pH is stable.

    day 8 since sprouting for the grape ape

    cloner
    pH 5.8
    ppm 330
    temp 72.4f
    ambient under the dome 79f 40%RH

    day 15 of flowering for the BB

    aero res
    pH 5.8
    ppm 700
    temp 68f

    water level is falling, EC is stable, pH is rising

    Used my better judgement and just left the res alone, I think I've proven to myself that a weekly change and topping up with RO is working.

    day 9 since sprouting for the grape ape

    cloner res
    pH 5.8
    ppm 330
    temp 72.4f
    ambient under the dome 45%RH 79f

    took the dome off again

    cloner res is getting changed today, just have to let the water sit and warm up a bit before I do it. It came out of the tap at like 44f.

    Made some significant changes to the program that runs my garden:

    - added a trim function that adjusts how long the plants are sprayed for, based off of average humidity over an adjustable period of time.
    - reworked how my light timer functions
    - reworked the light fader functions
    - added a bunch of debug lines

    I want to do something like thismfor temperature and humidity controlls. Kind of like a historesis loop, if temp or humidity going up and only a couple of points below target value, then nothing happens, system waits to see what happens if parameter still aproaching target it does nothing, only makes changes when values are diverging from set points or are not within a certain goldilocs zone.

    That's called the "deadband" range, (or D, or hysteresis), you do that by adding or subtracting a few degrees/percent of humidity from the setpoint and use that value in a conditional, I set that for my extraction fans, along with delays to prevent rapid cycling.

    The trim function is a little different, as in it is constantly (slowly) changing the spray times based off of the average humidity in a 500sec window. So just a basic closed feedback loop.
