I’ve been busy working on my replacement controller code, probably about 40% done. I keep getting caught up in generalities and my inexperience isn’t lending me any speed. I’ve got the math right, now I just need to tell the machine how to repeat the process reliably. I wish that I had started coding sooner, it’s a lot of fun.

Curious how or if you are priortizing actions? When leaf temp rises what do you do? Increase ventilation, co2, or nozzel spray time? Or decraese light intensity. Or?

That depends™

It tries to do easy things first

Target a VPD, and prefer user selected environmental variables.

1. extraction speed and duration
2. adjust feed times
3. adjust light intensity
4. suggest raising lights

The harder things involve analytics.

I'll have access to:
relative humidity (veg, flower, drying closet, ambient)
temperature(veg, flower, drying closet, ambient, cloner, moms, reservoir temperature)
leaf temperature, to calculate leaf vpd
CO2 (veg, flower, ambient)
EC 2 sources
pH 2 sources
water flow into the system (direct daily water usage, also accounts for evap waste)
exactly how much (in ml) pH up, down, and fert concentrate gets used (for addbacks)

-----MAYBE turgor pressure, but the sensor is very expensive (and delicate!). I don't know what further optimizations it would yield.

Energy usage (a better idea, I'm off by about $20 every month with what I do now)

demarcation of the log database from key points in the growth cycle, user definable, (ie, started veg, noticed 2" of growth on this day) so you can analyze all that data and get a better idea on what and when you need to do things.

I'll get suggestions on how to tune algorithms from the data.

But yeah, the real idea is to have a very linear environment, and the controller just helps you balance everything out. To make your job easy.


I don't have to think about shit. I scrub it out and fill it up when it needs it, just do normal maintenance like change filters and whatnot.


It's easy to use, I made it like that on purpose. Once it is setup properly the controller should not have to be touched.

Ideally, it will be able to guess what the best settings should be. I just need to watch my algorithm over a long period of time to make sure it doesn't do anything wacky.
