There are a few ways you can tell: full colonization of the grain in the jar by the mycelium, thick spots of solid white, and the mycelium growing up the side of the jar looking for more grain, substrate or fresh air (FAE, fresh air exchange) to begin fruiting.
How do you know when mycelium is fully colonized?
Check on your bin daily to watch it colonize. You'll see white spots start to expand from each point of grain spawn. Over time they will completely cover the surface of the bulk substrate. You should see small droplets of mushroom exudate.

Now that could indicate that it's not done. Growing if there are no other signs.
How long does mycelium take to fully colonize?
Optimal duration of mycelium growth 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.
How long does it take for a substrate to fully colonize?
Depending on how much spawn is used, colonization may take 5 days to 2 weeks. The more spawn used the faster the bulk substrate will colonize.
How long after inoculation should I see mycelium?
This typically occurs around four days after inoculation. The mycelium expands through the substrate in a three dimensional sphere. When the mycelium runs into another leap-off point, the mycelium fuse together until the entire substrate becomes one mycelial organism.
What does mycelium look like right before pinning?
Once the mycelium appears in the valleys of the casing layer, meaning you can see mycelium strands beginning to poke through the casing layer, but the surface of the casing is not yet colonized, you should initiate pinning.
When should I shake mycelium?
We typically shake the grain about three times during this process. The first time at this stage, the second when it's about half or two-thirds colonized, and the third time just before moving it to a second grain run.
Does mycelium need darkness?
The light is not necessary. Mycelium grows well in dark conditions. In commercial growing it is due to the cost cut. The light is mandatory for primordium formation and fruit boddies development.
How do you speed up substrate colonization?
Raising the temperatures can speed colonization, but can be dangerous - you can dry out the substrate, you can "cook" it if you use a heating pad method, you could overheat and risk thermal death (overheating is less forgiving than underheating).
Why is my mycelium not fruiting?
Not Enough Moisture Mycelium, the underground vegetative growth of a fungus, needs a moist environment to thrive and produce mushrooms. Mushrooms themselves are mainly water, so if you let the mycelium dry out or the humidity level get too low then nothing will happen.
What temperature does mycelium grow best?
75° F.Mycelium grew best during spawn-running when the temperature was kept at 75° F. (23·9° C.) During pre-cropping a temperature of 65° F.
How long can you keep fully colonized grain spawn?
Many people don't realize that you can store fully colonized spawn bags and grain jars for 2-3 months after they are colonized.
