Unlike tropical varieties, the button mushroom is a cool-season fungus that requires strict temperature control, high humidity, and a specific nutrient-rich growing medium to produce its classic, fleshy white caps.\u003c\/p\u003e\n\u003cp\u003eThe \"Seed\" (Mushroom Spawn)\u003c\/p\u003e\n\u003cp\u003eButton mushrooms grow from grain spawn, where sterilized wheat, sorghum, or rye grains are fully inoculated with button mushroom mycelium. Because Agaricus bisporus is highly sensitive to competing wild molds and bacteria, maintaining strict hygiene during the planting process is vital.\u003c\/p\u003e\n\u003cp\u003eQuick Care Guide\u003c\/p\u003e\n\u003cp\u003eThe Substrate (Compost): Unlike oyster mushrooms which can grow on simple straw, button mushrooms require a specialized, pasteurized synthetic or natural compost (usually a fermented mix of wheat\/paddy straw, horse or poultry manure, gypsum, and urea). The compost must be fully decomposed, dark brown, and entirely odorless before use.\u003c\/p\u003e\n\u003cp\u003ePhase 1: Spawning (Incubation): Mix the grain spawn thoroughly into the cooled compost and pack it into plastic trays, shelves, or bags. Keep the setup in a dark, clean room at a warm incubation temperature of 22°C to 25°C (71°F to 77°F). The mycelium will spread through the compost in about 12 to 14 days.\u003c\/p\u003e\n\u003cp\u003ePhase 2: Casing (Mandatory Step): Button mushrooms will absolutely not fruit without a protective soil layer. Once the compost is fully colonized by white mycelium, spread a 1-inch layer of sterilized casing soil (typically a highly water-retentive mix of coco peat, moss, and treated garden soil) evenly over the surface.\u003c\/p\u003e\n\u003cp\u003ePhase 3: The Temperature Drop (Fruiting Trigger): About a week after casing, when the mycelium starts peaking through the soil, you must lower the room temperature drastically to 14°C to 18°C (57°F to 64°F) and introduce fresh air (carbon dioxide reduction). This cold shock triggers the fungus to stop growing threads and start forming mushroom \"pins.\"\u003c\/p\u003e\n\u003cp\u003eWatering \u0026amp; Humidity: Keep the room's air humidity at a steady 85% to 90%. Spray the casing soil gently with a fine misting nozzle 1 to 2 times a day so it stays damp, but never let water pool or seep deep into the compost underneath, which causes the crop to rot.\u003c\/p\u003e\n\u003cp\u003eHarvest Tip: Button mushrooms emerge in distinct waves called \"flushes.\" Harvest them when the caps are tight, firm, and round, right before the veil underneath the cap breaks to reveal the gills. Hold the cap, give it a gentle twist, and lift it out cleanly from the soil. A single tray will typically yield 3 to 4 fresh flushes over several weeks!\u003c\/p\u003e","brand":"Roots and Stem","offers":[{"title":"Default Title","offer_id":47250377605291,"sku":null,"price":399.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0780\/6350\/1483\/files\/IMG-20260619-WA0014.jpg?v=1781898039","url":"https:\/\/rootsandstem.in\/products\/button-mushrooms-seeds","provider":"Roots and Stem NEW","version":"1.0","type":"link"}
