why all the fuss about contams? its a fight against time, contams vs myc. if myc grows first & faster it wins. if it stays strong it keeps winning IE resists contamination. set up a big tank or tote for fruiting with a cool mist vaporizer plumbed (get creative with hot glue n pool piping & cling wrap) into its lid, on a timer few min every few hrs NOT FULL TIME = fresh humid, but not wet air, and no fanning. put air inlet at bottom of tank to push c02 out. Leave small hole in lid to exhaust out of. Cling wrap draped over hole or otherwise keep air in & junk out... keep cakes away from inlet. casing is only for contams in a pf jar, hello you open the top (taped holes) to the air and shove a needle inside, but the straw log method or grow bag method cant really have a proper pre colinonized casing. after birthing casing is a water reservoir. Misting is to replace water in the reservoir See "PF dbl ended casing tek".. think about this... is the air outside filtered? dont they grow out there? . if you cased all sides of a cake how would light cause pinning? ever see a mushroom house? not sterile. you are making an environment for fungus. give the good fungus a better start and it wins. brown spots in jars on otherwise white myc is from the water sitting there between myc and jar. it/they excrete a "juice" For a base wipe jar, flip it, put lid on bottom, put cake on lid. tape lid to band and you have a perfect container for a casing layer, easy. toss lids and bands when rust gets too much. micropore or masking tape made zero difference in contam rate. micropore allows gas exchange esp in bird seed quart jars. Go bird seed and horse poo. easier to handle than bovine dung, get the dried, grey horse nuggets, one 20ish cup poo "cake" can and will make 2oz/wk. Cheaper than rye berries etc. turn old fridge or freezer into 80 or so degree incubator for jars. put small, see TINY, ceramic heater in fridge on temp controller off amazon. get the sunflower seeds out of the wild bird seed. they float. or buy sunflower seed free stuff. pasturize poo in pillow case submerged in water at 160F for 1hr. leave in pillow case and drain overnight in slop sink. spawn it next day. layer poo spawn poo. top with spawn and case it. put lid on container, toss in incubator till colonized, flip/birth, case the bottom that is now top, put in tank with cool mist...they are phototropic, put a light over it 12 hrs or so. not a grow light. a cpl flouros per 100gal tank. not close. 4ft is ok. like any hobby more effort yields more results. dollar store had small totes years ago about 8x10 0r 6x12 and 4inches or so deep..good reusable cake molds and bases to elevate off tank bottom. birth cake on lid, put lid on bottom of tote., make a glove box. not out of advice but out of beer. toodles
