Brown Oyster Mushroom Spawn, 1 Quart Jar
type: Product
description: Brown Oyster Mushroom (Pleurotus ostreatus) Grain Master For sale is a 1-quart jar of Brown Oyster 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 isolated this Brown Oyster culture separately from our Pearl line because it is a genuinely different performer. It runs harder, knits tighter, and fruits in heavy brown-capped clusters. Growers who run it once tend to keep running it. 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. Brown Oyster colonizes with real force and is a strong candidate for grain to grain expansion because it takes over a fresh jar quickly. It spawns to bulk as readily as any other ostreatus. Brown Oyster Growing Conditions Brown colonizes grain in 10 to 14 days at 70 to 78F and fruits 55 to 75F, the same envelope as Pearl. What is different is the vigour and the look. The caps come in a deep tan to chestnut brown rather than grey, and the clusters run dense and heavy. It behaves as a standard Pleurotus ostreatus in every technical respect, so anything that works for Pearl works here. Treat this as a colour and performance selection rather than a different biology, because that is exactly what it is. Spawn run 70 to 78F Grain colonization 10 to 14 days Fruiting temperature 55 to 75F Substrates Master's Mix, pasteurized straw, supplemented hardwood sawdust Difficult…
