Processing Infrastructure & Facility Zones

✅ Core Facility Zones to Plan

Zone

Purpose

Key Equipment

Notes

Cultivation

Lab, Fruiting and Incubation

Lab Equipment, Racks, humidifiers, HVAC

8,500–12,000 sq ft starting footprint

Drying

Reduce water content pre-processing

Tray dryers, dehumidifiers

May need >100 sq ft for each batch cycle

Extraction Lab

Convert mushrooms into liquid or powder extracts

Hot water extractors, alcohol tanks, ultrasonic?, filters

Controlled for heat, alcohol

Purification / Filtration

Clarify extracts or isolate components

Buchner filters, centrifuge, filtration columns

Optional at phase 1

Lab & Testing

Verify active content (e.g., beta-glucans)

Microscope, pH meters, drying oven

Partner with third-party lab at first

Formulation & Packaging

Final product prep

Capsule fillers, tincture bottlers, labeling machine

Needed for white-label or DTC

Storage

Hold dried mushrooms, extracts, and packaging

Racks, climate-controlled storage

Separate dry vs alcohol handling

Admin/Compliance

Records, testing logs, certifications

Workstation, secure data storage

🧪 Step 3.1: Core Equipment Breakdown

Cultivation & Drying

  • Cultivation Lab: ~$4000
  • Sterilization/Pasturization Equipment: ~ $3000
  • Fruiting tents/racks: ~$5,000–$10,000
  • Humidifiers, dehumidifiers: ~$3,000
  • Tray or shelf dryers (40–80 trays): $3,000–$6,000

Extraction Lab

  • Hot Water Extractor (20–50L): $5,000–$10,000
  • Dual Extract (with ethanol): +$3,000–$7,000
  • Vacuum filtration, Buchner funnel: $500–$1,500
  • Alcohol recovery system (rotovap or distiller): $2,000–$6,000

Formulation / Productization (Optional)

  • Capsule machine (semi-auto): $2,000–$5,000
  • Tincture bottler: $1,000–$2,000
  • Labeler + shrink sleeve: $800–$1,500

🏗️ Step 3.2: Suggested Phase 1 Facility Layout (within 8,500–10,000 sq ft)

Zone

Approx. Sq Ft

Description

Cultivation Area

5,000–6,000

Fruiting tents, incubation, air control

Drying + Storage

800–1,000

Near cultivation for fast hand-off

Extraction Room

800–1,200

Hot water + alcohol extractor, filter

Packaging & Formulation

500–800

Optional in Phase 1

Admin / Lab / Testing

300–500

Data, records, future certification

This layout fits within your first-phase budget (~$200K capex) depending on material cost and labor availability. Optimize for flow: cultivation → drying → extract → output.

⚙️ Step 3.3: Modular Scaling Strategy

Phase

Size

Output Focus

Notes

Pilot

8,500 sq ft

3-4 species, drying + dual extract

Proof of concept, build relationships

Phase 2

20,000 sq ft

Add packaging, in-house lab

Expand SKUs, serve ingredient market

Phase 3

Full acreage

Vertical integration + branded lines

Full capacity utilization, multiple markets

This strategy supports a "grow to match demand" model, minimizes waste, and helps you scale without outpacing cash flow.
