Urban mushroom farm · grown on coffee grounds
Mushrooms grow at night. We pick at dawn.
In two dark rooms behind a Prague courtyard, oyster and shiitake blocks fruit in waves — and what you pick up on Wednesday was still growing on Tuesday.
Grow rooms
Farming, but the weather is ours.
A mushroom is ninety percent water and one hundred percent environment. We keep the numbers steady so the flushes come like clockwork.

Harvest waves
Every block gives three flushes.
After colonising in the dark, a block fruits in waves — big, smaller, smallest — and then retires to the compost of a market garden nearby.
First flush
day 7 · ~60 % of yield
The big one — clusters double in size daily.
Second flush
day 14 · ~30 %
Smaller, denser, some say tastier.
Third flush
day 21 · ~10 %
The farewell — then the block becomes compost.
Species
Four mushrooms, four characters.
Oyster
Pleurotus ostreatus
The workhorse — fry it hot and fast, salt at the end.
Pink oyster
Pleurotus djamor
Loud colour, bacon notes — chef bait.
Shiitake
Lentinula edodes
Deep umami; the stems make the best broth.
Lion’s mane
Hericium erinaceus
Tears like crab meat — sear in butter.
