Where water
meets soil.

LINFA is a planter that waters itself. Water sits below, soil above, and the two never mix.

Water.
Soil.
Apart.

Too much water rots the roots. Too little dries them out. LINFA keeps water in a separate tank and brings it to the plant only when needed, in the right amount.

A few things.
Done well.

Here is what is inside LINFA.

The LINFA planter in exploded view: the parts stacked apart
Fourteen parts, one planter. 3D-printed and designed to be taken apart.
A bottle pours water into the refill cap on the back of the planter; the cutaway shows soil above and the tank below
Refill from outside. Take off the cap on the back and pour: water runs down into the tank, under the soil.
The white float resting on the water in the tank
It knows when water is running low. A float signals the minimum level in the tank.
