6.2 Facility and infrastructure

Figure 14. Growing rooms, plant and infrastructure capital.

Item	R	Depreciation life	Note
Six button growing rooms — structure, insulation, shelving	7 600 000	15 years	Phased three, then one, then two; the dominant capital item
Climate control, air handling and filtration	3 400 000	10 years	Temperature, humidity, CO2 and filtered air with positive pressure
Oyster house — pasteurisation, inoculation, fruiting rooms	2 150 000	12 years	Includes clean room for inoculation, the highest-risk step for contamination
Cold room, packhouse and cold chain vehicle	1 780 000	8 years	Non-negotiable given five to seven day shelf life
Solar, backup generation and water	1 320 000	10 years	Climate control failure loses a crop, not merely a day’s trading
Site works, roads, biosecurity and fencing	620 000	15 years	One-directional clean-to-dirty workflow designed into the layout
Technical advisory and pre-operating costs	480 000	3 years	Imported growing expertise through the first two crops
Total facility and infrastructure	17 350 000

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.
