Yeah the recipe is for a huge amount of soil, but if you were only needing a little, but have the space and what not for a compost pile I think it would be a great starter to just leave there outside and add compostable household trash as it becomes available, and in turn you get really good compost, because really that is what the supersoil is...Compost...lol. When he says he mixes it all up, wets it and leaves it in the sun, it is so everything composts and begins the awesome foodweb process...
