Okay! So I leave for college in less than 30 days, but I’d like to make sure my tomatoes to continue to grow once I leave so I’ve taken some steps to make sure that my departure goes smoothly.
Here’s a video of my revised setup:
There are a few key differences between this setup and my previous one:
The main one is that the watering system has been 100% re-vamped. The water distribution happens via a hose with holes in it instead of using the tray at the bottom of the plant grid in the previous video.
It also takes, uploads and tweets a picture of itself using a raspberry pi camera module.
It also creates a new mysql table every two weeks, and in turn, renders a new kind of graph. The renderscript.php file receives an argument from the python script which is the table code.
Here’s the python script:

Hey! This post was written a long time ago, but I'm leaving it up on the off-chance it may help someone. Proceed with caution. It may not be a good idea to blindly integrate this code or work into your project, but instead use it as a starting point.
