GROWW. is a minimalistic single-plant greenhouse for small flats in overcrowded cities. Core parts of GROWW. are 3D printed with only the jar made of glass. Suits both most common jars in the US & EU: wide mouth Mason Jar and 82mm diameter thread jar. It’s designed to be printed with PLA – a biodegradable thermoplastic derived from renewable resources. The gardening experience is easy to acomplish by adding soil, seeds & water to the inner pot, closing the jar and watching the plant GROWW.
