There are two ways to make a Nestpot. One way is to nest two inexpensive nursery pots for a Nestpot that will be used once and discarded. A second way is to nest two more expensive nursery pots that can be used, washed and reused many times. Both ways involve inserting a large nursery pot into a slightly smaller nursery pot.
A Nestpot has an upper chamber with soil connected by a wick to a lower chamber. The wick delivers water from the lower chamber to soil in the upper chamber. The Nestpot shown here is designed to be used once and recycled. After harvesting herbs or lettuce, the soil would go to compost, the wick would go to trash and the pot would go to recycle.
The components in the photo above are for a one time use Nestpot. The small pot on the left serves as the lower chamber. The slightly larger pot in the middle serves as the upper chamber. The two pots nested together on the right make a Nestpot. The bottom of the photo shows a wick with a knot at one end. The knot is necessary to keep the wick from falling from the top chamber into the bottom chamber.
A Nestpot viewed from above showing the knotted portion of a wick. The wick extends through one of the drain holes into the lower chamber. When Nestpots are placed in a shallow water source the wick delivers water to the upper chamber containing soil. The arrangement of upper and lower chambers prevents the soil in the upper chamber from being saturated with water.
The photo above shows Nestpot components that can be used many times. The upper and lower chambers are easily washed and reused after each harvest.
