Self-watering raised bed

Product Overview

The self-watering system (SWS) includes many

materials; cotton, wool, geo-textile, soil, gravel and even

wood to some degree. Every material has different SWS

properties which you can test by placing that material

into a glass of water and watching the water “climb” up.

When one end of the SWS is saturated and the other

end is dry, it creates a moisture gradient, which drives

the SWS until the gradient no longer exists or you run

out of water.

With the personal garden, the soil is suspended above

the reservoir with SWS dangling into the reservoir

pulling up moisture. As the plants use the moisture in

the soil, it creates a moisture gradient (the soil is drier

than the reservoir) which drives moisture through the

wicking into the soil like a vacuum effect.
