The bag is ready to inoculate as soon as it arrives.<\/p>\n<h2>What Is Grain Spawn?<\/h2>\n<p>Grain spawn is grain that is fully colonized by mushroom mycelium. Growers mix it with bulk substrate to start a grow. Because corn kernels are large, each one carries plenty of energy. As a result, corn makes strong, fast grain spawn.<\/p>\n<h2>How to Make Grain Spawn with This Bag<\/h2>\n<ol>\n<li>First, wipe the bag where you will inject with alcohol.<\/li>\n<li>Next, inject 5\u201310 ml of <a href=\"\/product-category\/liquid-cultures\/\">liquid culture<\/a> with a sterile <a href=\"\/product\/bd-microlance-injection-needles-18g-1-piece\/\">18G needle<\/a>.<\/li>\n<li>Then cover the hole with micropore tape or an injection port.<\/li>\n<li>After that, let the bag colonize at room temperature.<\/li>\n<li>Finally, mix the colonized grain with <a href=\"\/product\/mushroom-substrate-bag-4000cc\/\">mushroom substrate<\/a>.<\/li>\n<\/ol>\n<p>In addition, the large 4000cc bag is ideal for big grows.
