Yes, the kits are great. But they are 35 bucks each - the spawn (inocoluated grain) is 40 bucks a bag which will do probably 40 buckets at least, which means about 40 times more mushroooms! And I can re-use the buckets - less plastic waste from the bags as well. It's a complicated process but I'm hoping I can get a handle on it and do it every year!
