About

Mycomansion is the working journal of a home mushroom cultivator — substrates tested in a small dedicated space, fruiting chambers dialed in over years of failures and refinements, and species notes that have actually fruited under the conditions you can reproduce in a basement, spare room, or closet.

The site grew out of a habit of writing things down: which substrate ratios produced solid colonization on Lion’s Mane, what humidity drift killed an early pink oyster flush, and which low-cost monotub builds matched the consistency of larger rigs. Those notes became the guides on this site.

The core focus areas:

• Gourmet species — Lion’s Mane, Oyster, Pink Oyster, Chestnut, and Shiitake: temperature, humidity, and CO₂ parameters that actually hold up in a home setup.
• Substrate & spawn — masters mix, supplemented straw, hardwood pellet blends, and grain spawn ratios documented from a real working rotation rather than theory.
• Sterile technique — agar work, liquid culture, still-air boxes, flow-hood builds, and the contamination signatures to watch for before they take over a block.
• Fruiting conditions — Martha tent designs, monotub configurations, and seasonal humidity targets that mimic autumn.
• Setups & builds — the smallest reliable kit that produces consistent flushes, with an emphasis on starting cheap and upgrading only what fails.

Every guide here is built from at least one full cultivation cycle in the author’s own setup — never armchair theory. More about Kenny →
