It is additional source of moisture, some kind of stress and sign for mycelium, that "no more nutrients further! Hurry up! Form fruit body, spread spores and save your genus!" And boom! Fruits are coming! For Shiitake - sawdust, wood pellets, wood chips, seed hulls.Ĭasing - a layer of substrate over bulk substrateĬasing is low nutrient substrate, usually the layer about 1/2 inch (1-1,5 cm). For Hericium species aka Lion's Mane - sawdust, bran, seed hulls. Other substrates usually used for edibles. What can be used for fruiting substrates?Ĭoconut coir, hay, straw, grain hulls, manure, compost, sawdust, paper products, wood pellets, wood chips, corncobs, coffee plants and waste, tea leaves, sugarcane bagasse, banana fronds seed hulls (cottonseed, sunflower, and oil-rich seeds) almond, walnut, pecan, peanut hulls soybean meal, roughage (okara), and soy waste artichoke waste cactus waste: saguaro and prickly pear, yucca, agaveįor Psilocybe cubensis and Natalensis coco coir mix is the most popular bulk substrate.įor Panaeolus species is manure based substrate, also hay and straw can be added to the mix.įor Psilocybe azurescens - sawdust, paper products, wood pellets, wood chips. We'll discuss possible options in our guide later In fact, for Psilocybe Cubensis spawn to bulk is optional, but it can significantly increase your yield. Bulk substrate vary and depends on the mushroom genus and species (actives and edibles). Spawn to Bulk - transfer grain spawn to secondary fruiting substrate (bulk) for further bulk colonisation (spawn run) and mushroom fruiting.Such transfer allows you to spread the mycelium (spawn run) for the next step of mushroom cultivation - mushroom fruiting period. Fruiting substrate is a source of additional water and ingredients for mushroom metabolism and fruit development Bulk substrate is less nutrient than grain substrate. Bulk substrate for mushroom fruitingīulk substrate - secondary substrate in mushroom cultivation also called fruiting substrate for producing mushrooms (after spawn to bulk). It is recommended substrate recipe for PF-tek growing we discussed later 2. It is a mix of BRF (1 part), vermiculite (2 parts) and water (1 part). Newbie growers also choose substrate based on the brown rice flour (BRF). Wheat berries, oats, barley, corn, popcorn, brown rice, rye, wild bird seeds (WBS), millet, sorghumįungi love any grain from the list above. Also cellulose is a common source of nourishment for cultivated fungi. Until too much nutrients mycelium continue colonisation phase (mycelium formation) and don't produce mushroom fruits on this step.įor spawn we should use whole grain (in husks) only! The shell of the grain have cellulose (fiber) that protects each kernel against clumping, excess moisture and further bacteria contamination. Grain is a highly nutrient, rich in carbohydrates substrate for rapid mycelium production. In sterile grain substrate spores propagate and create mycelium network. It is used for the first steps of cultivation process almost for all mushrooms, actives and edibles. The first substrate for mycelium growing is grain substrate. Spawn - culture of mycelium on grain substrate Please, don't skip it! Types of substrates for magic mushroom growing: grain substrate, bulk and casing 1. This overview will help you to connect the dots. Usually newbie growers confuse what is what.Įach type of substrate has specific features, different content and it is used on different steps of mushroom cultivation process While it is languishing in a syringe (minimum for 24 hours) and waiting for inoculation, it's time to take care of the substrate for future magic mushrooms.īefore the next manipulations I'd like to explain you briefly some differences between substrates. Choose the substrate for mushroom cultivationĪt this step, you've already prepared a liquid spore syringe.
