The Gourmet Mushroom Problem
Gourmet mushrooms are delicious and healthy, but are rarely available.
Poor quality and limited variety in stores
Gourmet mushrooms in stores are limited in variety and often sweating inside plastic packaging. You’ll pay a premium for poor quality and wasteful packaging due to their short shelf life. They're typically imported from overseas so by the time they hit your kitchen, they’re often well past their prime.
Foraging is high effort, low yield
Deadly lookalikes exist, foraging requires expert knowledge for safety. Even when found, wild mushrooms are often past their prime or insect-infested, and the short seasonal window makes foraging more effort than reward.
Hard to grow at home
Mushrooms thrive in humid, cool climates — they're sensitive to variable climates and the dry warm air of homes is not suitable. Unless you live in a rainforest, consistent fruiting is a big challenge.
Grow kits require daily misting
Grow kits are a fun low-cost option but they require constant misting, multiple times a day for at least 7 days. If you go away for a weekend, your mushrooms will most likely dry out and fail.
Bulky equipment and DIY setup
Serious growers rely on plastic tubs or grow tents with bulky equipment to manage humidity, CO₂, and temperature. These setups are best hidden in a garage and demand serious DIY effort to duct in humidifiers, fans, and heating or cooling systems.

As expert mushroom growers, we’ve seen a lot of home growing setups and Flush has set a new standard. Flush takes care of all the hard work, providing the ideal environment for beautiful, healthy mushrooms - even those more difficult to grow species. It’s a seriously impressive unit and a game-changer for home mushroom growing.

We’d never grown mushrooms before, but we were curious to try it out. Honestly, we were blown away by how easy it was with the Flush cabinet. We kept waiting for something to go wrong, but it just worked. Super simple and actually really fun.
