Cover the bowl with a lid or foil and let it sit for 1 hour.

No pressure cooker needed.\u003c\/p\u003e\n\n\u003ch3\u003eCan I mix coco coir with vermiculite?\u003c\/h3\u003e\n\u003cp\u003eYes. Many growers use a 50\/50 coco coir and vermiculite mix. The vermiculite improves water retention and air exchange in the substrate. Our brick works well with this method.\u003c\/p\u003e\n\n\u003ch3\u003eHow much does one brick make?\u003c\/h3\u003e\n\u003cp\u003eOne brick expands significantly once hydrated and typically fills a standard monotub when mixed with grain spawn.\u003c\/p\u003e\n\n\u003ch3\u003eCan I reuse the substrate after a harvest?\u003c\/h3\u003e\n\u003cp\u003eSome growers reuse their substrate for a second or third flush by rehydrating and maintaining humidity. Results vary depending on contamination levels after the first harvest.\u003c\/p\u003e","brand":"EasyMushroomCultivation","offers":[{"title":"150 Grams","offer_id":50045040722259,"sku":"CC-SML","price":3.49,"currency_code":"EUR","in_stock":true},{"title":"300 Grams","offer_id":50045040755027,"sku":"CC-MED","price":5.49,"currency_code":"EUR","in_stock":true},{"title":"600 Grams","offer_id":50045040787795,"sku":"CC-LRG","price":6.99,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0883\/3758\/0371\/files\/premium-organic-coco-coir-brick-substrate.webp?v=1780685045","url":"https:\/\/easymushroomcultivation.com\/en-es\/products\/coco-coir-mushroom-substrate","provider":"EasyMushroomCultivation","version":"1.0","type":"link"}
