How much gypsum do I add to grain?
5% is for bulk substrates; gypsum is beneficial at both stages.
I add about a tablespoon of gypsum per quart of grain and I add it to the simmer not the soak.
I soak, rinse, then simmer so if I added it to the soak all the gypsum would be rinsed off.
Gypsum just sort of coats the grains..
How many pounds of substrate do you need for a Monotub?
The substrate should be about three to five inches high in the tub. A 3-pound bag should be able to inoculate one or two moderately sized tubs.
How do you sterilize a mushroom substrate?
Pasteurization at 60-80°C, up to 5 days, and 0 Psi. Super-Pasteurization at 80-100°C for around 15 hours and 0 Psi. Pasteurization and especially Super-Pasteurization, which was introduced by Paul Stamets, is a widely used method when it comes to sterilizing the substrate.
How much lime do I add to mushroom substrate?
In conclusion use of 2% lime is good for the production of Oyster mushroom (Pleurotus spp.) using cotton waste as a substrate. The Oyster mushroom grows well and give best yield at pH slightly basic in nature.
Do you need Gypsum for grain spawn?
You need gypsum in your grain jars. If you don’t use it the starches in your grains will cause them to clump together.
How do you pasteurize a mushroom substrate?
The most common way to pasteurize the substrate is simply to submerge it in boiling water for at least one or two hours. For most operations, we have found that pasteurization is sufficient to grow mushrooms with minimal risk of contamination.
How do you sterilize a mushroom substrate without a pressure cooker?
You have to put the mushroom substrate in a hot water immersion tub. The temperature range up to 80 degrees Celsius. Leave the substrate in hot water for 60 to 90 minutes. Let it dry for 120 minutes.
How long does it take mycelium to colonize jars?
they can take 3 weeks to start showing growth and can take up to 2 month to fully colonize . while these are at the long end of the time frames its still possible to take this long.
What is CaSO4 2H2O?
Gypsum is a common mineral. … Gypsum is composed of calcium sulphate (CaSO4) and water (H2O). Its chemical name is calcium sulphate dihydrate (CaSO4. 2H2O). Gypsum can be milled mixed with water and then resume its original rock-like state.
What is the best mushroom substrate?
Hardwoods such as oak, beech and maple make for a great substrate for many types of mushrooms, especially when combined with a bran supplement. Soy hulls can be mixed with hardwood sawdust at different ratios to produce extremely effective and high yielding substrates, particularly for growing oysters.
What is the PF TEK method?
PF Tek is a method of mushroom cultivation pioneered by Robert McPherson, aka Psylocybe Fanaticus, T.P. & Nanook. … The sterilized “PF jar” is then injected with a solution containing spores and water from a syringe, creating a one step procedure for reliably growing mushrooms indoors.
Should I case my Monotub?
They don’t need a casing layer at all. But some will say case and others will say no need. It’s all about personal preference and what fits your needs, growing situation and style IMO. I personally always case, but I like to give my fruit as much FAE as possible and often let them grow in open air.
What is gypsum used for in mycology?
Gypsum is used in in grain spawn in order to keep kernels from becoming stuck together and as a pH-buffer and lightening agent in bulk substrate and casing material preparation. …
How do you get perfect grains to spawn?
4 Steps to Making Grain SpawnStep 1: Rinse and clean the grains, soak in water for 12-24 hours.Step 2: Cook the grains for 15-20 minutes so that they absorb water.Step 3: Drain and dry excess moisture from the outside of the grains.Step 4: Load grain into mason jars and sterilize for 90 minutes at 15 PSI.
Do you have to sterilize mushroom 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.
