The Cambodian strain was found by John Allen when he was along his trip in Asia. Now it is a very widely grown mushroom that has many fans. Cambodia cubensis fruits very soon in the process and needs little attention. Therefore Cambodia spores are a good one to start with if you are not an experienced cultivator (yet). When grown on rice flour, the mushrooms can grow very large. The caps of the mushroom will form an umbrella like shape that have wide rims and have a distinct brown/red color.
