was looking through and looks like some stuff is not quite right in that second one the docs wbs one is good so far though
edit: except that cotton ball looking thing I dont know what that is, have you seen the lets grow mushroom videos that Roadkill and RR made?? look up lets grow mushrooms on youtube or on a torrent site there some what informative and those guys are pros
2nd edit: this is a bag method not jars but this method is flawless from what I can tell unlike the previouse two I posted everything seems uptodate maybe someone else can post you a jar method thats correct sorry the first two i posted might have giving you some wrong info, like i never use pollyfil, coffee filters are kinda useless to, I use 4 injection holes at least two not one big one, also dont put your jars in on there side like in that one tek also foil over the lids is a good thing also keeps water from dripping into your jars and helps keep contams back a bit
