Growing Green Cities Greenhouse

The initial working title for this project was the ‘Stedelijke Kas’. Currrently it’s in the process of renaming it to ‘Growing Green Cities Greenhouse’.


I have already built a Facebook community on Stedelijke Kas, its name will also soon be changed.

The ‘Growing Green Cities Greenhouse’ is a small business effort to reach the following goals per family:

– 80% trash reduction
– 50% food expenses reduction
– 50% drinking water reduction
– 30% energy reduction

On the facebook page and on this site we will post regular updates on the progress of the project.


One of the key features of the Growing Green Cities Greenhouse is that it use aquaponics. Aquaponics is a food production system that combines conventional aquaculture (raising aquatic animals such as snails, fish, crayfish or prawns in tanks) with hydroponics (cultivating plants in water) in a symbiotic environment.

Energy Reduction

A greenhouse captures the heat energy of the sun in order to make plants grow better. The warmth also makes it possible to grow plants that otherwise would not grow in a colder climate. On sunny days, a Growing Green Cities Greenhouse will generate lots of excess heat.

This excess heat can be captured and stored underground. This means the earth itself will be used as a heat battery in the Growing Green Cities Greenhouse. When this battery is fully charged, it can be uncharged at night in order to heat not only the greenhouse itself but also the home attached to it.

Waste Reduction

One of the most intriguing possibilities of having a Growing Green Cities Greenhouse is that waste processing becomes a lot easier. Nature is very good at dealing with trash. With a greenhouse we get a substantial amount of nature ‘extra’ in our backyard. This can be used in various ways to decrease our trash volume.
