I'm trying to build my own sprouting system for every kind of sprouts.
Obv, there are a lot of prepackaged tool (like this one for example), but they are very expensive considering that they are only made of plastic! So, I fend with some cheapest solution (stacked colanders and collector for water).
Now, I'd like to improve my own "creation" adding to it a mini-sprinkler to sprinkle water at predefined intervals. The idea is similar to the sprouter in this photo, where you can see the helical sprinkler at the top of the sprouter.
However, I don't know where to start and what to buy and I'm here to ask your help.
Thanks in advance to everyone.
