CapiHealth™ self-watering system

Is it possible to have both more water & a smaller container?
Yes indeed.

The CapiHealth™ automatic self-watering irrigation system is equipped with many key features having a tremendous impact on the Christmas tree health.

CapiHealth ™ automatic waterer irrigation system:

has a variable water reservoir capacity dynamically optimized relatively to the Christmas tree diameter (see animations)

allows room for up to about 350 % more water (refer to the animations' bottom captions)

So, no need for a huge water reservoir

allows a small reservoir = small Christmas tree stand

has a capillary wick (in white in the animation) watering the Christmas tree untill the last drop of water
