Verdant Fungi Farms Business Plan — Operations and the Room Build

The build from three rooms to six and 840 m² to 1,680 m², Phase III compost supply, climate control and the crop cycle behind 6.7 turns a year.

Growing rooms and climate control together are 63 per cent of the capital budget, and both must be complete before a single mushroom is sold. The cold room, packhouse and delivery vehicle are front-loaded because a five-to-seven day shelf life makes the cold chain a condition of trading rather than an efficiency. Site works are front-loaded for the same reason: one-directional clean-to-dirty workflow has to be designed into the layout, not retrofitted around it.

6.3 The crop cycle

Stage

What happens

Where the risk sits

Cook-out

The emptied room is steam-sterilised before refilling

Skipping or shortening it lets a contaminated crop seed the next one. It costs turnaround days, which is exactly why it gets shortened

Fill and spawn run

Phase III spawned compost is loaded to the shelves and held at spawn-run conditions

Compost quality determines the ceiling on this crop. Nothing later recovers a poor delivery

Casing

Casing layer applied and managed to trigger pinning

The most skill-dependent step, and where imported technical advice earns its cost

Pinning and fruiting

Environmental control brings the crop through successive flushes

Several hours without climate control loses the crop. This is what backup power protects

Harvest

Picking to grade across two or three flushes

Picking discipline affects both yield and grade. Over-mature product downgrades

Cool and pack

Immediate cooling, grading and packing in the packhouse

Field heat not removed quickly costs shelf life at the far end

Despatch

Cold chain to wholesale, retail or restaurant within hours

Five to seven days from here. Unsold product is loss, not inventory

Roughly eight weeks from cook-out to final flush for button, and about five for oyster. The plan’s improvement from 5.4 to 6.7 crops a room a year comes almost entirely from compressing the days between crops rather than from shortening the biological cycle, which cannot be rushed.
