They counsel initial building grain spawn after which using it to inoculate your bulk substrate. This is due to grain spawn is easier to crack apart and distribute evenly through your substrate, growing the colonization amount and decreasing the probability of contamination.
Figuring out how for making a liquid culture is helpful for tiny-scale residence growers along with the components and machines are comparatively very easy to supply.
