Our Chestnut is a first-generation Pholiota adiposa isolate chosen for reliability. It colonizes rye readily, accepts a range of bulk substrates and keeps producing flush after flush from the same block, which makes it one of the best yield-per-pound cultures we sell.
Where many species give one good round, Chestnut keeps coming back from the same block.
Nutty, mild caps on stems that stay crunchy through cooking. Sauté whole clusters stem and all.
Fruits at 50–70°F alongside Blue Oyster and Shiitake, so it fits a fall and winter rotation.
Let the syringe reach room temperature, then shake it gently to break up and spread the mycelium through the broth.
Flame the needle until it glows, let it cool a few seconds, and wipe the injection port with the included alcohol pad.
Use 2–3cc per quart jar or 3–5cc per 3–5 lb grain bag. One 10cc syringe inoculates about 2–4 containers.
Keep it at 65–75°F in the dark. Shake once at about 30% colonization to speed things up.
Rehydrate between flushes: after each harvest, soak or mist the block to replace lost water, then return it to fruiting conditions. That's what keeps the later flushes coming.
From our lab to your grainRun it into jars with wide-mouth cultivation lids or your own lids with self-healing injection ports. Spare 16G needles and sterile Luer Lock syringes are sold separately.
Use 2–3cc per quart grain jar and 3–5cc per 3–5 lb spawn bag. One 10cc Chestnut syringe inoculates roughly two to four containers. Using more doesn't speed colonization much; it just uses up the syringe.
About 18 days at 65–75°F. Once the first primordia appear, clusters mature in about two to three weeks.
Rye berries for spawn, then supplemented hardwood sawdust or straw for bulk. Supplemented sawdust gives the most flushes per block.
Several. Chestnut is reliably multi-flush, so expect multiple rounds from one block when you rehydrate it between harvests. That's a big part of why it's a favorite for growers trying to get real food from limited substrate.
Refrigerate it at 35–45°F in the bag it shipped in and never freeze it; freezing ruptures the cells and kills the culture. Bring it to room temperature and shake gently before you inject.
Liquid culture is living mycelium from an isolated culture, so it skips germination, colonizes days faster and gives genetically consistent fruits. Spores have to germinate and pair up first, which is slower and more variable from grow to grow.
Liquid culture is living mycelium, so every syringe leaves our lab in a foil-lined insulated mailer. The insulation buffers it against summer heat in a delivery truck and against sub-freezing winter temperatures, so it arrives viable either way.
When it arrives: refrigerate the syringe at 35–45°F until you're ready to inoculate. Never freeze it. Bring it to room temperature and shake gently before use.
Myco Labs never disappoints! I'm having great success with these cultures + their grain bags & masters mix substrate.
Injected into my bag and the grain was fully colonized in about 3 weeks. I spawned it to bulk, and it took about a week to fully colonize and it's ready to pin! I'll be buying all of my LC from Myco Lab.
