>>786347>Is there a particular good place to get freshly-felled tree logs? Call up local landscaping and tree cutting companies. Tell them what you want to do, give them your number to call you if needed. You'll need something to haul a log in of course. A good diameter is 6-12 inches thick and no more than 3-4 feet long.>If you grow fungi out of a log, do you have to do anything to it, like water it?Yes, there's a good bit of work in involved, if you want highest yeilds, but it can be easy enough. Some people use a shock tank to dunk the logs in water for 12-24 hours. Other people just use a garden sprinkler overnight on them. There's resting periods between flushes too. My shiitake logs are currently dormant for several weeks (reposted pic related). I'll shock them again later on to get more.
Google up several sources of info:
