I've read elsewhere that I can grow shiitake mushrooms by soaking logs/branches, drilling holes in them and inserting spores into the holes.
Since I already have some white button mushrooms from the supermarket, I'm wondering whether using spores from those would work, using a similar technique. I don't want to buy a mushroom growing kit because unless I understand the principles involved I'd probably need to keep buying new kits, which is neither economical nor sustainable.
If a wood based medium is not the best, then is there something else easily obtainable I can use instead? eg Would any of the following work, if spores were added and they were buried (in a damp but not boggy area):
- grass clippings (dry or wet)
- kitchen scraps
- wood chips
If a bucket in a garden shed is better than burial, then that would be fine too.
I can sterilise small volumes of material by boiling, which in some case I understand is important.
In any case, I'm unlikely to use a volume of material that's more than 2-3 buckets in size, due to space constraints. I don't know whether this would affect the viability of any methods.
