A new user on this site, this is my second post on this site.
Since California is in the state of drought, I was looking for ways to save water and still be as frugal as possible. I experimented with home made drip systems as you can see in attached pictures. Basic usage was to take easily available materials in the house and try to use it. I have tried systems with milk containers/yogurt containers and to-go containers that you get from many places. A small hole to container and twine threaded through it makes nice drip. Twine expands and clogs the hole, so there is no water leak and it drips slowly. Milk container has two schemes - either small drip attached for small area or soaker hose attached for larger area.
I use water collected from shower and kitchen to water my plants.
