Its worth reading through the thread, he never wrote a tek on it, but that thread describes everything in detail. There are four holes around the top, and two near the substrate level. The holes are covered with micropore tape, and the substrate is spawned in the bucket, leveled out, and a shower cap thrown over the top, pushed down, and the bucket is thrown under a blanket to colonise. Once colonised and starting to fruit, the shower cap can be lifted up to increase fresh air. To fan the bucket, the shower cap can be lifted up and down like a lung - pulling in filtered air through the micropore covered holes. The best option however is to have a small fan on in the room, but not pointing at the buckets, to keep air circulating. This eliminates the need to maually fan and basically keeps them as a completely automated neglect tek. You can mist every few days if you want to stop things drying out. The whole thing is protected from fungal gnats so these won't ever be a problem again using buckets, and if a contamination occurs in a bucket, its isolated from the other buckets and can be disposed of easily. These can be used to fruit anything, King oysters perform really well in buckets.
