How long does substrate need to pasteurize?
In general a compost substrate temperature of 140° F for 4 hours is adequate for a complete pasteurization. To insure a complete pasteurization it is suggested to have a minimum of 2 hour crossover time, where both the air and compost substrate at 140° F together.
What does it mean to pasteurize substrate?
What is Substrate Pasteurization? This is the process whereby you reduce the number of microscopic elements in a growing substrate. This provides the mycelium leverage over harmful microorganisms, thus overriding the substrate and subsequently producing mushrooms.
Is it better to pasteurize or sterilize substrate?
Do You Have To Sterilize Mushroom Substrate? For some varieties of mushroom substrate, sterilizing is necessary to avoid contamination. For other kinds of substrate you can get by with only pasteurizing it.
How do you pasteurize large amounts of substrates?

How do I pasteurize a substrate without a pressure cooker?
Place your substrate above a steaming pot of water for 3-4 hours. Like this, you can get pretty close to sterilization. Temperatures will only reach about 212F compared to 250F in a pressure cooker. Place your substrate in the oven at 350 for 3-4 hours.
How do you sterilize substrates in bulk?
Simple Oven Sterilization of Mushroom Substrate / Casing
Do I need to pasteurize my bulk substrate?
When moderately nutritious bulk substrates are pasteurized at 140-175°F (60-80°C), some beneficial micro organisms, mainly bacteria, stay alive, inhabit the substrate and guard it against other, more aggressive micro organisms.
How do you sterilize a substrate?

At what temperature you will keep your soil for pasteurization?
Soil pasteurization kills pathogenic organisms and weed seeds using aerated steam. It is customary to apply steam for 30 minutes beyond the time when the coldest spot in the batch of root substrate being pasteurized reaches 140 degrees F (60°C), although many growers pasteurize at a temperature of 160 degrees F (71°C).
Can you sterilize substrate in the oven?
Do you have to sterilize your substrate?
Sterilization of the substrate is one of the critical steps when it comes to mushroom cultivation. Without a good sterilized substrate, the level of contamination within the substrate is too high for the mycelium to grow. This, therefore, leads to low yield or even worse to a total loss.
How long should I sterilize substrate?
Sterilisation time: about 3 – 4 hours. Roll down the autoclave bag about 10 cm and pour in 2.5 kg of the wood substrate mixture.
How do I pasteurize bulk substrate in the oven?

Does coco coir need to be pasteurized?
Although coco coir is already resistant to bacteria, pasteurizing it before use won’t harm it and will ensure a healthy growing season. Other mediums can be added to coir during the pasteurization process and, depending on the mix of substrates, the length of time it is exposed to heat can vary.
Do I need to sterilize my substrate?
What temperature kills bacteria in soil?
Soil pasteurization kills pathogenic organisms and weed seeds. Pasteurization uses aerated steam and a temperature of 140 degrees Fahrenheit for half an hour. Some beneficial microbes remain. Soils can be treated to 180 F to sterilize the soil, but this temperature can produce toxic byproducts.
What are the 4 methods of soil sterilization?
The four most common methods for sterilizing soil are: Oven sterilization. Solarization. Steam sterilization.

Do you have to sterilize substrate?
You should fully sterilize the substrate. Always follow the sterilization method with no exceptions. Check the pressure regularly when using a pressure cooker to achieve a heat sterilization.
Can you sterilize substrate without a pressure cooker?
Do you need to sterilize bulk substrate?
Any substrate with high amounts of supplementation must also be sterilised to ensure the healthy vigorous growth of mycelium.
How do you sterilize a coco coir substrate?
You can sterilize growing mediums such as coco coir by placing them in an oven heated to 180 degrees F for 30 minutes. This effectively kills pathogen eggs and larvae as well as harmful fungi. Microwave. You can heat-sterilize small amounts of moistened coir in the microwave for three to five minutes.
How do you pasteurize coir and vermiculite?
Spring or purified water is heated to 160-180 degrees Fahrenheit and poured over the coir. Then the bucket is capped with a lid to retain heat and allowed to sit for one to two hours.
