{"id":87,"count":0,"description":"Our <strong>mushroom spawn<\/strong> is fully colonized grain, ready to use. We inoculate sterilized grain with an isolated culture of the strain you choose. Then we let it grow in our lab until every kernel is white. As a result, you skip the slowest and riskiest step of the grow.\r\nPick a 2 L or 4 L bag and choose your strain at checkout, from Golden Teacher and Jack Frost to APE and Penis Envy types. Because we grow each bag after you order, it takes 2 to 4 weeks to prepare.\r\nWhen it arrives, break up the grain and mix it with <a href=\"\/product\/mushroom-substrate-bag-6000cc\/\">coir substrate<\/a> in a monotub or grow bag. Not ready yet? Keep the bag in the fridge at 2\u20138\u00b0C for up to two weeks.\r\nPrefer to make your own grain spawn? Inject our <a href=\"\/product\/grain-spawn-bag-with-sterilized-corn\/\">sterilized corn<\/a> with a <a href=\"\/product-category\/liquid-cultures\/\">liquid culture syringe<\/a>. We ship fresh mushroom spawn from the Netherlands across Europe.","link":"https:\/\/mycosupplies.eu\/en-gb\/product-category\/mushroom-spawn\/","name":"Colonized Grain Spawn","slug":"mushroom-spawn","taxonomy":"product_cat","parent":0,"meta":[],"menu_order":0,"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v28.8 (Yoast SEO v28.8) - https:\/\/yoast.com\/product\/yoast-seo-premium-wordpress\/ -->\n<title>Mushroom Spawn \u2013 Colonized Grain Spawn | MycoSupplies<\/title>\n<meta name=\"description\" content=\"Mushroom spawn, ready to use: fully colonized grain spawn in 2 L or 4 L bags, in the strain you choose.
