When is mycelium ready

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. How should primordia look like? Powerful, homogeneous hemispheric formations, appear at the slits and, as a rule, completely fill the perforation area. 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.

This can be caused by the following reasons:. Read more here. 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. After that keep the temperature constant, without swings. In such cases the block tends to overgrow in spots.

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 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.

Spawn is mixed through the compost and the thread-like mycelium carried by the spawn grows and colonises the compost. Growth is initially slow, but after seven to eight days the mycelium grows exponentially. When the compost has been completely colonised by mycelium, growth stops of its own accord.

This is indicated by the compost activity. Activity is the difference in compost and air temperature combined with the movement of air through the compost in a tunnel or around the compost in a growing room. Abundant growth causes a lot of activity, sparse growth causes little activity. There is a simple answer to what the optimal time for colonisation of the compost is.

The compost is fully colonised at the moment that activity decreases. The precise length of time this takes varies per system, season and type of compost. Generally speaking the optimal time is 16 to 19 days, but there are certainly also exceptions.

If the compost is colonised in the growing room, it is left there so the mycelium stays intact. This is a big difference compared with compost that is incubated in a tunnel. Please enable JavaScript in your browser to complete this form.
