Common Myco abbreviations: MS - Multi spore (a spore print or spore syringe is a multi-spore sample) FAE - Fresh air exchange. The process of maintaining fresh air in your fruiting chamber, it is important to exchange the fresh air often to keep mushrooms growing. BRF - Brown rice flour. An ingredient used in substrates. Most mushrooms can easily consume brown rice flour thus making it a valuable nutrient source. Inc - Incubator. A device used to keep substrates warm while they are colonizing. The Myco101 kit comes with an incubator. Verm - Vermiculite. A substanced used as a partial ingredient in the PF style substrate jars.It helps to grow mushroom mycelium. PC - Pressure Cooker. An important peice of equipment used to sterilize substrates. Mushbox carries a selection of All American Pressure Cookers and Sterilzers. TiT - Tub in tub incubator. A simple device used to keep substrates warm during colonization. RH - Relative humidity. This is the current level of water vapour mixed with the air in your fruiting chamber. FC - Fruiting chamber. Any type of chamber that simulates the environment necessary for fruiting mushrooms. G2G - Grain to grain transfer. A mycology process that involves moving mycelium from one substrate to another to initiate new growth. GB - Glove box. A device used to maintain a sterile environment when conducting mycology procedures like inoculation or grain transfer. PE - Penis Envy, a strain of cubensismushroom. LC - Liquid Culture, a medium for germination of spores and growing mycelium. Myc - Mycelium, the vegetative growth of fungus. Mycelium starts forming after the spores germinate. Learn more about mushroom reproduction. Myc Piss - Yellow or amber substance formed from mycelia metabolites. Usually forms in the substrate jars or bags after long periods of colonization. Hpoo - Horse Manure, a common substrate ingredient. Cpoo - Cow Manure, a common ingredient used in substrates. Opaque - non-clear surface; light does not pass through it Spawn - refers to a chunk of mycelium that has colonized a substrate. WBS - Wild Bird Seed, a common substrate ingredient. Common Temp and Humidity Settings: Incubation Temp = 78-82 degrees. Use a dark and dry environment like a closet or a tub-in-tub. Fruiting chamber = 68-72 degrees with 95% Relative Humidity. To induce fruiting add about 8-12 hour of light in a 24 hour cycle.
