they can take 3 weeks to start showing growth and can take up to 2 month to fully colonize .

Similarly, you may ask, how long does mycelium take to fully colonize?

After two weeks to a month (depending on temperature and substrate size) the substrate will be fully colonized and it's time to change environment. During incubation the mycelium should be kept in a dark and warm place.

Similarly, how long does PF cake take to colonize? 1 pint jars take between 3 and 5 weeks to reach full colonization (but do not forget to wait at least 7-10 days after full colonization).

Correspondingly, how do I know when mycelium is fully colonized?

There's no guaranteed way to know, but that's a good rule of thumb. If you take it out of the jar before the inside is fully colonized, it will sit in your FC doing nothing until it is anyway and open to contam for that much longer.

Should mycelium be kept in the dark?

Light. A commonly held belief among growers is that mycelium will grow faster in total darkness. There is no data to support this premise; however, significant exposure to direct UV light from the sun can be detrimental.

What temperature does mycelium die at?

Constant temperatures higher than 74 degrees usually prevent mushrooms from growing, and temperatures over 86 degrees for several hours can kill the mushroom mycelium (the fungus).

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. If you need to wait or delay a bulk growing project, keep reading!

How do I make mycelium colonize faster?

The least nutritious substrates, such as straw, colonize fastest. If the mycelium is hungry, it will grow faster and more rhizomorphic in search of food. If you provide a very rich substrate, the mycelium will colonize it, only slower.

What causes mycelium to fruit?

Fresh Air Exchange (FAE)
Lower levels of CO2 are also a signal for the mycelium to create fruit bodies. Again, in nature when the mycelium reaches the outside of the dung pile, there is much more fresh air than inside the pile.

When should I see mycelium growth?

Sometimes you can see mycelium growth a day or two after you knock up a jar but not allways. In rare conditions sometimes it could take up to 2 weeks. Just be patent and put the jars in a dark innoculation chamber between 75-80 degrees and you will be fine.

Does freezing kill Mushroom spores?

Spores are fine at at these low temperatures, it's just not good if spore syringes get frozen solid as that can kill the spores. Spore prints can handle the freezing temperatures much better since they are not frozen in crystals. After all spores do freeze and thaw in nature.

Does mycelium need air?

Mushrooms exhale carbon dioxide like we do and need to breathe in fresh air like us. During their incubation period mycelium can actually tolerate high levels of CO2 but require respiration so as to not promote bacteria who can tolerate no oxygen.

What does mycelium smell like?

Earthy, and "clean" smell.. its hard to tell, but its much easier to smell when something is gone wrong. Such as when bacteria is present, it'll generally smell sour like wet gym socks.

How do you water a mushroom?

Water - Water your kit by sprinkling or spray misting water on to the kit's surface once a day. In this case you would be watering the black plastic bag with the ¼ inch holes in it. When the small oyster mushrooms being to force themselves out of the bag holes in 3-7 days, increase watering to 2-3 times a day.

What does mycelium look like?

Mycelium Structure. To the naked eye, fungal mycelia appear like a ball of cotton. Here, a network of hyphae bundle together to form mycelia, which are found on substrates, soil or underground where they obtain nutrients. Unlike fungal hyphae, mycelia are highly branched, which makes it visible to the naked eye.

Do spawn jars need light?

Place the jars in a safe place out of direct sunlight. Indirect light is all that is required. If the temperature is kept around 70 degrees, germination will begin within 3 to 5 days.

How many jars can I inoculate with one syringe?

Use 1 cc per jar. This will allow the syringe to inoculate 10 jars. You can actually use more spore solution per jar (speeds colonization) but then you won't get as many jars per syringe. If the syringe needle plugs up as you insert it into the PF substrate, just draw the needle back a little and it will unplug.
