I used an RPi for my hydro system, I grew a few generations of really good green "tomatoes" and had quite amazing yields... satisfied my geek side and my gardening side all at once... :)
Sounds interesting - any how to guides or you making up as you go along? Thx for sharing
The basic ebb and flow tech is simple. I'm prototyping it with a simple hardware timer. For now my plan is to simply add a programmable switch and some sensors once the system is up and running and go from there (maybe a webcam).
Here's an example video (mine is more DIY with less pretty containers): https://www.youtube.com/watch?v=60uokf3WmTo
I'll try my hand at tomatoes and maybe chilli peppers. The initial goal was to grow as much as I can which goes into home cooked chilli :)
