Self-watering container how do they work

paulsiu(5a)March 3, 2013

Most self-watering container consist of a reservoir with a cloth wick on the bottom of the container. How does this work, wouldn't that mean the bottom of the pot get wet? How does the water work against gravity to wet the rest of the plant? Doesn't how the water work through the plant depend on the type of soil?

The article tells me how to construct a self-watering style container, but how does it work? Is it Capillary action that makes the water travel up the growing media against gravity or will the rest of the growing media be dry and it's only the bottom of the growing media is going to be wet?

Yes, capillary action. Works really well with the correct mix.
