Cakes are a silly way to do bulk grows, way too much work, takes up way too much space too.
I can easil yget 100g dry on one flush in a kitty litter tray of proper medium.
I still say whoever thinks a cube is a cube has not had a propper transkei cube.
Its pretty legend around my circles, some fear it some love it, I've seen it give experienced shroomers uncontrolable laughs for 4 hours on less than a gram.
Its not very visual, and visuals have a yellow tingle rather than the traditional rainbow coloured fractals.
Also it looks slightly diffirent to other cubes, the stem is often quite gnarly, often hairy at the base, it overgorws ANY casing and you have to keep burrying it, or it makes these large innersole spongey like growths on top of your tubs.
