Cómo empezó

Por ahora esta página está en inglés. La versión en español está en camino.

We built the first planter with members of the Hudson Guild Fulton Senior Center. They told us something we had not designed for: they had gardened for years and stopped, not because they lost interest, but because the beds were too low to reach comfortably and needed watering every single day.

So the bed sits at waist height and holds roughly two months of water. It went through more than a year of prototyping with residents and program directors before we delivered the first one in June 2023.

Cómo funciona

Three semi-corrugated pipes run under the soil and hold the water. A fill pipe in one corner is the only part anyone touches — you pour water in there until the pipes are full.

As the soil above dries out, water seeps through perforations along the length of the pipes and the roots draw it up. Nothing is pumped and nothing is powered. When the pipes run empty, you refill them, which works out to about once every two months.

    Building the first planter

    We bought the birch and built the frame in the school maker workshop, weather-proofing every face before the sub-irrigation pipes went in.
