How do you Innoculate substrate with spawn?
Open the sterilised wood substrate bag. Use 2 to 10 % (of target substrate mass) of grain spawn for inoculation of wood substrate. Add about 50 – 250 g of grain spawn per bag containing 2,5 kg of wood substrate. Close the inoculated substrate bag using a bag sealer or strong adhesive tape.
What is Pftek?
The PF Tek is a technique that was originally developed to grow the psilocybin containing magic mushrooms (psilocybe cubensis) at home with common household items. Now it is often used for the cultivation of gourmet mushrooms such as oyster mushrooms.
Does mycelium need oxygen?
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.
How long do substrate jars last?
All Jars and Spawn Bags are prepared fresh and meant to be used within 4-6 weeks of receiving the items. You can extend the shelf life by a few weeks by placing items in the fridge or storing in a cool dark place.
How many days after mycelium is inoculation?
Once inoculated, the mycelium takes upwards of 10 days to jump off the spawn into the substrate.
Where do jars go after inoculation?
Put your newly inoculated jars on a shelf at room temperature and away from direct sunlight. There is no need to “incubate” grain at warm temperatures in the dark, since the mycelium will grow happily in normal room temperature conditions.
What do you need for PF Tek?
The ratio as dry volume is approximately:
- 2 parts of vermiculite, i.e. 2 cups of vermiculite.
- 1 part of rice flour, i.e. 1 cup of rice flour.
- 1 part of water, i.e. 1 cup of water.
Should mycelium be kept in the dark?
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.
Should I shake my spawn jars?
Since we use jars, the agar sticks to the side of the jar. So instead of shaking the agar into the jar, we leave it on top. In this image you can see how the mycelium grows through the agar and starts to colonize the grain. When the colonization looks like this, we shake the jar for the first time.
How long does mycelium take to colonize jar?
about 1-3 weeks
Depending on the species of mushrooms, it can take about 1-3 weeks before the jar is fully colonized. At this time you can either add it to a bulk substrate or do a grain to grain transfer to make even more spawn!
How do you know if grain spawn is contaminated?
In grains, bacterial contamination appears dull gray, slimy, excessively wet, similar in appearance to mucus, and is easy to identify by taking a big ‘ole whiff of your grain jar when you suspect it is present. As the nickname “sour rot” suggests, if your grains smell sour, you’re probably dealing with Bacillus spp.
What to do after inoculating jars?
Put your newly inoculated jars on a shelf at room temperature and away from direct sunlight. There is no need to “incubate” grain at warm temperatures in the dark, since the mycelium will grow happily in normal room temperature conditions. You should shake the jar at least once during colonization.
What are PF Tek jars made of?
The basic PF tek substrate is a mixture of brown rice flour and vermiculite, but flours made from other grains, such as rye or millet, can work, too, and the vermiculite can be replaced with other materials, such as coco coir. How Do I Know if My PF Tek Jars Are Contaminated?
What is the best PF Tek substrate?
What Is the Best PF Tek Substrate?

How Do I Know if My PF Tek Jars Are Contaminated?
What equipment do I need to grow Tek mushrooms?
Plus, the tek requires only commonly available supplies, and no specialized equipment is necessary. PF tek is very popular among Psilocybe growers (that’s the vaunted “magic mushroom”), but will also work with any legal, culinary mushroom able to grow on grain.
