Space Vegetables - #11 | Weekly update #0 (1st Week)

Hello everyone ! Hope everyone is safe and sound.

 

Yesterday was the first week that the project went live and things are still pretty much in the beginning.

Since my TDS sensor hasn't arrive yet, I'm following the schedule in the manual of the nutrients company. You can check this post - Space Vegetables #9 : "Huston, we have liftoff" - when the project went live .

 

It was time to add nutrients to the water (three part nutrients)

image

and to check the PH level of the water - always about 30 minutes (and a watering cycle) after adding the nutrients, because the nutrients alter the water PH - to above .

the following week I'm planing to make this automatic with the PH sensor.

The Vegetables

After a week I can already see some changes - the plants have grown. image  I'm happy with the progress so far.

 

 

 

The beans have grown and I can tell because they are touching the lights - will do something about that - they will not grow much more - this bean quality has been chosen specifically because they don't grow much taller.

The other plants have also grown.

I had to change 4 of the plants because they were dry. When replacing them I realized that the fault was mine - when transplanting them last week, I accidentally broke them in the stem ...

Since I'm taking picture every 10 minutes for a final time lapse, here's a video from those pictures of the first week.

 

NOTE: The "pulses" you see on the video is the water cycle ! image

Software

The software is going well - everything is working . Environmental conditions are monitored and registered.

The lights turn on and off and scheduled times. Finally I was able to procure a power source with enough amps to power both red/blue lights and white lights. I'm only using one output (for the lights) from the Automation HAT MINI .

The Air pump and water pump both are working well and they turn on and off when instructed.

 

I've added Telegram notifications for when all this happens so I can keep an eye on all of this.

image

 

I've also added a function to check if it's time to turn the lights -when a power outage occurs - since the lights are schedule to turn on at 08:00 and turn off at 18:00 (06:00pm), when a power outage occurs, in a reboot, it's not sent again. So, when it occurs, the server (the automation hat mini) will check if it's in the interval to have the lights turned on or not. If it is, it calculates the time left until the 18:00 and keeps them on during that time.

When I post about the software, this will all be explained better there.

 

The information in the display of the HATs are also added, but still not in production. Will be added next weekend.

 

Happy codding.
