Tiny water feeder pipes that clip to all of your plant pots
All you would need is a fitting to connect to the tap, a timer device and a stack of thin pipes that you clip to each pot – then once set up you never need to feed them again. If some pots are large, just put 2 or 3 of the pipe endings in each one. I would buy this if someone made it.
Just use the feeder pipes and drippers from this set.
Its called an irrigation system. Google it.
I used to work in a plant nursery where these are used everywhere and automatically timed. I pinched all the bits I needed to make a small version at home but they got trashed by my cat. Now though I see someone is gonna make them if they get enough funding. Please fund it, I want one for me and one for my nana too.
