Self-feeding, Self-watering Pot (Video)

In this video, Daniel Catalaa of San Francisco explains the design for a planting pot which combines the benefits of self-watering and self-feeding in a single unit. This is not a new idea, but a combination of two existing ideas into a single unit. It has a large water storing capacity and uses earthworms to create and spread compost in situ.

It will take roughly about six hours to build it at an approximate cost of 100 dollars. The benefits of this design are free fertilization, plants stay watered when you are away and the device produces excellent yields.

  1. Good idea, but not finish developed.
    You are breeding Mosquitos!
    Every hole or gap larger than 1.2 mm ( to standing water is breeding Mosquitos.
    I’ve also build a self-refilling on-demand watering system for pot plants.
    Mosquito-save was one important design goal.


  2. Small-scale Aquaponics:
    I find a lot of plant-cuttings, and have veggie cuttings. To start them I put them in water and/or vermiculite; and, i was wondering that if i put a small fish and a air plant in a bowl, maybe with some gravel to promote aquatic cultures, and set the cuttings in a small tray, that might be a good way to stare the cuttings?

  3. Good idea for small places or if your out of town traveling. Where are the worms for the composting?
