Reishi Mushroom Spawn, 1 Quart Jar

Reishi Mushroom (Ganoderma lucidum) Grain Master For sale is a 1-quart jar of Reishi Mushroom Spawn. This is a generation 1 grain master mushroom spawn jar used for expansion of isolate mycelium, optimized for spawn run times and bio efficiency. Out Grow has isolated this Ganoderma lucidum culture for dense conk formation and strong lacquered surface development. What a G1 Grain Master Is A grain master is a jar of fully colonized grain made to be transferred, not consumed. Generation 1 means the mycelium in this jar came directly from one of our agar plates rather than from another bag of grain, so it sits one step from the culture library instead of three or four. That matters because every transfer is another opportunity for contamination to ride along, and because a G1 jar still has the full expansion runway ahead of it. One quart can seed several more quarts of sterile grain, and those can seed your bulk substrate. How to Use This Jar Rest, break, recover, transfer. Reishi is a vigorous coloniser at warm temperatures and expands readily. Spawn to sterilized supplemented hardwood sawdust, oak for preference. Reishi Growing Conditions Reishi colonizes grain in 14 to 21 days at 77 to 86F, which is warmer than anything else in this collection except Pink Oyster, and it fruits warm too, from 70 to 82F. It is a long cycle species, often two to three months from pinning to harvest. The form you get is controlled entirely by your environment: high carbon dioxide and low light give you the antler form, while good fresh air exchange and light give you the flat lacquered conk. Both come from the same culture. It is a wood decay fungus and it wants hardwood, not straw. Spawn run 77 to 86F Grain colonization 14 to 21 days Fruiting temperature 70 to 82F Substrates Supplemented hardwood sawdust, preferably oak Difficulty Intermediate Season Warm season Note Antler versus conk form is controlled by CO2 and light Storage and Shelf Life Refrigerate at 35 to 40F. Warm to room temperature for a day before transferring. Do not freeze. How It Is Used Reishi is too woody and bitter to eat. It is dried, sliced and simmered into tea or extracted into tincture. We make no health claims about it. Guarantee and Live Shipping Every jar is inspected before it leaves our lab and guaranteed to arrive alive and contamination free. If it does not, photograph the jar sealed and unopened and contact us within 48 hours of delivery for a replacement or refund. Live spawn is temperature sensitive, so we hold shipments during extreme heat and cold rather than sending something that will not survive the trip. Browse the rest of the mushroom spawn collection.
