How to grow oyster mushrooms at home?
Oyster mushrooms are the easiest gourmet species to cultivate. They grow on almost any cellulose-based substrate, fruit in 7-14 days, and tolerate beginner mistakes.
- Indoor monotub for year-round high-volume production4
A monotub is a large plastic storage bin modified for airflow and humidity, allowing continuous indoor mushroom production regardless of season. Serious growers use monotubs to produce 5-15 lbs per month from a closet-sized space.

- Inoculate hardwood logs for outdoor production4
Drilling holes in freshly-cut hardwood logs and filling them with plug spawn produces oyster mushrooms outdoors for 3-6 years per log. Low maintenance after setup — the logs fruit naturally in spring and fall rains.

- Grow on used coffee grounds — zero-waste substrate3
Fresh spent coffee grounds are already pasteurized by the brewing process and provide a nutrient-rich substrate for oyster mushrooms. Most coffee shops give away spent grounds for free.

- Bucket tek — pasteurized straw in a 5-gallon bucket5
The bucket tek is the most popular beginner method for growing oyster mushrooms. Straw is pasteurized in hot water inside a 5-gallon bucket, mixed with grain spawn, and fruits within 2-3 weeks. One bucket yields 2-4 lbs of mushrooms per flush.
