I'm starting a small farm of "selfwatering" Sub Irigatet Planters ( SIPs ) in Berlin, Germany this Year. This blog will act as a diary, to map and share the progress, experiences and results of this project. I will grow a wide range of rare / old vegetable species & varieties. I will also try different designs of homemade SIPs and test different custom soil mixtures. My goal is to find cheap, simple, effective and easily replicable means of urban gardening in Berlin City. Ultimately I want to make this system as sustainable and environmentally friendly as possible, by using largely recycled materials and soil mixtures that are based on as local and renewable resources as possible.
