In addition to providing an efficient logistics partnership for the two farms, we and our farmers’ market customers find that our products go really well together. On the other side, my neighbor Bianca sells wild foraged and organically grown mushrooms for the other Berks-based business, Lenhartsville’s Primordia Farm. On one side of our stand, I sell grass fed artisan cheese, yogurt, and cultured butter for Valley Milkhouse, a microdairy located less than 90 minutes from Philly that’s run by my friend Stefanie Angstadt. We’ll set up folding tables and tents on the sidewalk along with organic vegetable growers, kraut makers, fishermen, orchardists, urban farmers, and bakers who are there to vend at the farmers’ market. Just about every Saturday, I wake up early and walk a few blocks from my West Philly apartment to Clark Park, where I’ll meet a truck laden with cheese and mushrooms from Berks County. This month, she quick pickles some gorgeous local mushrooms from Primordia Farm! Take it away, Alex! – mycelium itself is weak, sieved or home made with a violation of technology.Regular Food in Jars contributor Alex Jones is here today with her contribution for the April Mastery Challenge.
PRIMORDIA MUSHROOM HOW TO
Please read how to add mycelium to the substrate here. In the future, they can heat a block, but only by their own development, and growth of oyster mushroom mycelium is suppressed and may cause a death of such block. In places where the mycelium is concentrated there will be local self-heating and active growth, while in other places of the block a competitive microflora will develop – spores of molds or bacteria. In such cases the block tends to overgrow in spots. – Mycelium badly mixed with the substrate or mycelium added in layers (so-called “zebra bags”).
After that keep the temperature constant, without swings. Bags after incubation must be moved into a room with a temperature of at least 20 degrees, so that they do not cool down, otherwise the initial growth speed of fungal hyphae decreases significantly. – improper heat treatment of the substrate. This can be caused by the following reasons: If the mushroom block is poorly colonized, and it does not heat, this means that mycelial growth activity of the the oyster mushroom block is very weak. If you have a bizonal cultivation system and you move the blocks from the incubator to the fruiting room, then it is best to do this at the stage of the ” primordial nod or at the beginning of primordia formation. How should primordia look like? Powerful, homogeneous hemispheric formations, appear at the slits and, as a rule, completely fill the perforation area. At first they appear in the form of small dots, the size of poppy seeds, white in color, then the mushroom buds grow to the size of a pinhead and start to become gray. Then mushroom rudiments or primordia appear. It looks like a white fluff or a piece of cotton wool. It begins with the appearance of the so-called primordial nod, which occurs under the film in the immediate vicinity of the perforations. In the photo on the right, the perforations are not open. In a living bag near the perforations, a fluffy layer forms – it is the start of primordia formation. The difference is visible even in the opening of perforations (holes). On the left it is a photo of a fully colonized bag ready for fruiting. It’s hard to explain in words, but in the photos, I think you’ll see the differences – on the right – there is a block overheated during incubation stage, and the white color under the film is faded. With a slight pressure, it is tight to the touch and slightly springy. When mycelium is ready to produce fruit bodies, the substrate becomes uniformly white, the block becomes not loose anymore. At 22ºС, blocks can grow twice as fast as at 18ºС.
