Cultures & cloning
Sterile lab work: starting genetics, agar plates, transfers, and liquid culture.
How to Clone a Mushroom from Tissue
Clone the genetics of a single fruit body by transferring a sterile tissue wedge to MEA agar, then cleaning the isolate over 2-3 transfers. The end result is a working culture you can scale on liquid culture or grain.

How to Pour Agar Plates for Mushroom Cultivation
Mix a 4% malt extract agar recipe, pressure cook it at 15 PSI, pour 20 to 25 plates per liter in a still air box at 115 to 125°F, and end up with sealed plates that store cleanly for 4 to 8 weeks.

How to Do an Agar Transfer (Sector Isolation): A Step-by-Step Guide
Read a plate, pick the strongest rhizomorphic sector, flame a scalpel, cut a small wedge from the leading edge, and slide it onto fresh agar. Two to three of these in a row turns a messy starter plate into a stable, named isolate.

How to Make Liquid Culture for Mushrooms: A Step-by-Step Guide
Mix a 4% sugar solution, sterilize it in modified jars, inoculate from clean genetics, and end up with a fast, reusable culture you can scale to grain.

Spawn
Grain prep and spawn-to-spawn transfers that bridge the lab to bulk substrate.
How to Prepare Grain Spawn for Mushrooms: A Step-by-Step Guide
Hydrate rye or oats to field capacity, sterilize at 15 PSI for 90 minutes, inoculate from a verified liquid culture, and shake at 30% colonization to finish in 14 to 21 days.

How to Do a Grain-to-Grain Transfer (G2G): A Step-by-Step Guide
Use 50 to 100 grams of fully colonized grain to inoculate a fresh sterilized jar. With clean source genetics and good still-air discipline, fresh quart jars finish in 7 to 10 days.

Substrate, fruiting & harvest
Bulk substrate, fruiting chambers, flush management, and harvest decisions.
How to Mix CVG Bulk Substrate for Mushrooms: Step-by-Step
The community-default bulk substrate for cubensis-style genetics and most oysters: 1 brick coir, 4 quarts vermiculite, gypsum to taste, hydrated to field capacity with boiling water. Cheap, repeatable, and forgiving.

How to Set Up a Monotub for Mushroom Cultivation: Step-by-Step
Drill the tub, mix the substrate, spawn at a 1:2 ratio, and dial in fresh air exchange. The complete monotub tek from empty bin to first flush.

How to Harvest Oyster Mushrooms: Step-by-Step Timing Guide
Harvest just before the cap edges flatten and curl up. Twist the entire cluster off at the base, store unwashed in a paper bag in the fridge, and reset the block for the next flush.

How to Dunk and Re-flush a Monotub: Step-by-Step Guide
Pull the colonized cake, submerge in cold water for 4 to 12 hours, drain for 30 minutes, and put it back in the tub. Done right, dunking adds a second or third flush worth 60 to 80 percent of the first.
