Generation 1 means the mycelium in this jar came directly from one of our agar plates rather than from another bag of grain, so it sits one step from the culture library instead of three or four. That matters because every transfer is another opportunity for contamination to ride along, and because a G1 jar still has the full expansion runway ahead of it. One quart can seed several more quarts of sterile grain, and those can seed your bulk substrate.\u003c\/p\u003e\n\n\u003ch2\u003eHow to Use This Jar\u003c\/h2\u003e\n\u003cp\u003eRest, break, recover, transfer. Wine Cap is an outdoor bed species and this jar is best used either to expand into more grain, or to inoculate a hardwood chip or straw bed directly. Spread it through the bed material rather than layering it on top.\u003c\/p\u003e\n\u003ch2\u003eWine Cap Growing Conditions\u003c\/h2\u003e\n\u003cp\u003eWine Cap, also sold as King Stropharia, is one of the most productive outdoor mushrooms you can grow. Build a bed of hardwood chips or straw in a shaded spot, work the spawn through the material rather than layering it on top, keep it damp, and it will produce for several seasons while improving the soil underneath. Grain colonizes in two to four weeks at 70 to 81F and beds fruit at 50 to 70F. Indoor fruiting is possible with a pasteurized casing layer, though the outdoor bed is where this species genuinely excels. Caps run burgundy red and can reach dinner plate size in a well established bed.\u003c\/p\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eSpawn run\u003c\/th\u003e\n\u003ctd\u003e70 to 81F\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eGrain colonization\u003c\/th\u003e\n\u003ctd\u003e2 to 4 weeks\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eFruiting temperature\u003c\/th\u003e\n\u003ctd\u003e50 to 70F outdoors\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSubstrates\u003c\/th\u003e\n\u003ctd\u003eHardwood wood chips, straw, chip and straw beds\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eDifficulty\u003c\/th\u003e\n\u003ctd\u003eBeginner outdoors\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSeason\u003c\/th\u003e\n\u003ctd\u003eOutdoor, spring through autumn\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eAlso known as\u003c\/th\u003e\n\u003ctd\u003eKing Stropharia\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eNote\u003c\/th\u003e\n\u003ctd\u003eOutdoor wood chip or straw bed cultivation\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eStorage and Shelf Life\u003c\/h2\u003e\n\u003cp\u003eRefrigerate at 35 to 40F.
