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

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 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.

You're on a roll with the dates now.
Plants looking good.
Just got 2 green crack and 2 blue dream at about 15" I just moved under the 1000w. Probly start a new journal. Debating on scrog again as I can only get into 1 side of my tent. But I cant argue with the yield for the trouble.
What's your favorite training so far?

Thanks man, thanks for stopping by.

I like GC and BD, wife got them from the dispensary a couple times.

I think my favorite is scrog, I can only get to the front of my tent too but there's plenty of space for me to do under canopy maintenance with only one plant in there. Once the stretch is over it's been the easiest to take care of and it makes good use of my 4x4. Those green ties work pretty good too at letting you make the plants cover more sq ft.

I've been thinking about getting some

and using a grabber I already have to take care of the back, but it didn't really need a lot of help from me.
