Description
Chestnut Mushroom (Pholiota adiposa) Grain Master
For sale is a 1-quart jar of Chestnut 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 Chestnut culture for tight cluster formation and the deep chestnut cap colour the species is named for.
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. Chestnut is a straightforward coloniser on grain and expands cleanly. Spawn to sterilized supplemented hardwood sawdust or Master's Mix.
Chestnut Growing Conditions
Chestnut colonizes grain in 14 to 21 days at 68 to 75F and fruits at 50 to 60F, so plan it for a cool room or a cool season. It responds well to strong fresh air exchange during fruiting, which is what gives you the short stems and full caps this species is grown for. Sterilized supplemented hardwood sawdust or Master's Mix are the substrates to use. Fruits come in dense clusters of golden brown caps on pale stems, and the flavour is nuttier and more distinctive than most cultivated species.
| Spawn run | 68 to 75F |
|---|---|
| Grain colonization | 14 to 21 days |
| Fruiting temperature | 50 to 60F |
| Substrates | Supplemented hardwood sawdust, Master's Mix |
| Difficulty | Intermediate |
| Season | Cool season |
| Note | Needs strong fresh air exchange |
Storage and Shelf Life
Refrigerate at 35 to 40F. Return to room temperature for a day before transferring. Do not freeze.
In the Kitchen
Crunchy stems and a nutty, almost peppery cap. Holds texture better than most and is excellent roasted whole in clusters.
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.
