Mosses and lichens are not generally used in green architecture and gardens in Canada, despite being widely used elsewhere in the world. This may be partly due to a lack of products that promote or incorporate them as landscaping elements. We built a low-cost growth cart specifically for mosses and lichens, called the “Moss Machine”, and tested its ability to grow four types of moss over 4.5 months in an indoor setting. Moss growth ranged from 1.5-4.5 cm over the duration of the study, with differences primarily due to species identity. The primary opportunity for improvement appears to be around the timing, duration, and overall management of watering regimens. We discuss other limitations and benefits of this initial design and recommend improvements for the next stage of development.
