The inventor that brought you AutoPot Technology is the Mini Twin Wall Pot.
This twin-wall self-watering pot has a miniature smart-valve that allows for a growing module with a smaller pot volume.
Ideal for smaller varieties such as smaller orchids, herbs, etc... for placement indoors on a window sill or a table.
The picture of the "clear" model demonstrates how the outer wall (reservoir) stores the water, whilst the inner compartment (where the plant resides in an inner sleeve) has a different water level regulated by the miniature smart-valve.
You can literally see the wet-dry cycle in action.
The reservoir stores water which will be drawn down by the smart-valve after each dry cycle for your plant.
The smart-valve now incorporates adjustable silicone stoppers to always get a perfect seal for the floats.
