Hello all ! Hope all be safe and sound.
Welcome to the third update for the Space Vegetables Project.
Plants
The plants are growing well, although I'm sensing a pattern and don't know why - or at least, don't know if it's from it.
The plants in the top layer are growing bigger than the ones on the bottom. The lights are the same and they are at the same distance from them (at least, apparently).
They are the same quality - at least some, and they don't show the same development. Will do some tests during this week - like changing plants from bottom to top and watch their progress.
I've also placed a guide (a fishing weight tied to a wire) to direct a bean sprout into the right place. Let's see how it goes.
PH sensor
The PH sensor was finally put to work. I've detailed it in here - Space Vegetables - #16 | PH reader
Although I've tested it in the nutrients solution and the PH reported is not the same measured by the PH solution that I have... And I trust more the solution than the sensor 
Will have to do more testing and calibration .
LCD
Finally I've put the HATs LCDs working. They display the current status (when something changes) during 10 minutes and then it turns off the display .
Enviro
The Enviro HAT shows how the environment is going. It displays the values from temperature, humidity, PH and TDS.
Automation
The Automation HAT displays the status of the pumps and the lights. If they are on, it displays On or nothing if not on.
Automation HAT MINI
My Automation HAT MINI LCD is kind of busted. Don't know what's happening, but it shows a perfect picture when starting, but during the progress of the script, it starts showing the picture and the text weird.
Weekly time lapse
And, to terminate, here's the time lapse from the plants "dancing" at night, from start until this week.
Happy coding and good progress in your projects
