ARBOK-AgroVac (AAV)

Overview

ARBOK-AgroVac is a next-generation plant factory: a sealed, containerized farm with multi-tier aeroponics and unmanned AI control, operated not at ordinary atmospheric pressure but in a managed sub-atmospheric vacuum, with CO₂ dosed above ambient levels to the plant optimum. Low pressure relieves the central limit of closed-environment farming — slow gas exchange — and, combined with tuned light, hydroponics, nutrition and climate, lifts yields by 1.5–3 times without expanding the footprint. Water is closed in a loop through ARBOK-Puri, biosecurity is handled by ARBOK-Trinity, nutrition by ARBOK fertilizers (ARBOK-FERTILIZER organo-mineral line), and lighting is conventional LED powered by ARBOK's own generation — cheaper than solar panels and available 24/7 (solar stops at night; ARBOK generation does not). The process itself is energy-light at ~0.72 kWh/t. The result is predictable, year-round production independent of weather, season and imported fertilizer.

Applications

Primary use cases:

• Year-round production of leafy greens, herbs and salad crops for local markets

• High-value vegetables and berries (tomatoes, peppers, cucumbers, strawberries)

• Accelerated nursery for seedlings and tree propagation

• Medical cannabis and medicinal/aromatic plants

Typical scenarios:

• Local urban supply with no cold chain and minimal logistics

• Deployment on non-arable land — deserts, rocky wasteland, rooftops, cold latitudes

• Off-grid, autonomous food production in crisis or remote zones

Not suitable for:

• Cereals (wheat, corn, rice) — they require vast areas and cheap field mechanization and remain in the open

Scale:

• Module: one 45 ft high-cube container, 59–117 m² growing area

• Commercial farm: 10 modules on ≤400 m² footprint (stackable)

Operating Principle

Plants feed on gases, and dense air slows their gas exchange: at ground-level pressure (~100 kPa) CO₂ reaches leaf cells slowly. AAV lowers total pressure to a managed sub-atmospheric level while holding the partial shares of gases in the correct balance and dosing CO₂ above ambient to the plant optimum (excess CO₂ beyond that optimum closes the stomata and harms the plant). Gases move faster, the leaf "breathes" freely, the enriched CO₂ reaches the leaf sooner, and evaporated water in the sealed volume is recovered rather than lost.

Key steps:

1. Seeding into multi-tier aeroponic/hydroponic trays

1. Pump-down and maintenance of the target sub-atmospheric vacuum level

1. Precise gas dosing (CO₂ raised above ambient to the plant optimum, oxygen balanced)

1. AI-controlled light, nutrition and atmosphere; unmanned vegetation period

1. Closed water recovery via condenser and ARBOK-Puri

1. Harvest every ~30 days, up to 12 cycles per year

External validation: independent plant-physiology research demonstrates that operating below ambient pressure measurably increases net photosynthesis while reducing dark respiration, supporting the yield-uplift case at the pressure levels used in the system.

Limitations:

• Requires a vacuum-tight, reinforced shell

• Not economic for staple grains

• Energy demand is low (~0.72 kWh/t), supplied by ARBOK's own generation (cheaper than solar, 24/7)

Architecture and Components

Core components:

• Vacuum-tight, reinforced 45 ft high-cube container shell

• Variable-speed vacuum pumps sized to maintain the target vacuum level

• Precise gas-dosing unit (CO₂ / O₂)

• Multi-tier aeroponic and hydroponic trays under LED light

• Closed water loop with condenser

• Sensor network and AI expert control system (unmanned operation)

Auxiliary / ARBOK modules:

• ARBOK-Puri — purifies and recycles any water source (tap, desalinated, recycled, brackish)

• ARBOK-Trinity — biosecurity; with low O₂ partial pressure and the sealed shell suppresses mold, fungi and insects

• ARBOK fertilizers — raise yields further

• Power from ARBOK's own generation — cheaper than solar and running 24/7 (on-site renewables optional)

The system is modular and stackable; capacity scales by adding containers.

TRL

TRL 4 (concept; hypobaric plant growth validated in laboratory studies); concept documented in an ARBOK preprint (June 2026, Zenodo/ResearchGate, DOI pending).

Evidence:

• Documented growth and full life cycle of crops under sub-atmospheric pressure

• Measured photosynthesis gain under reduced total pressure

• Mature underlying technologies (aeroponics, vacuum, water purification)

Remaining steps:

• Integrated module prototype and pilot farm

• Validation of combined yield uplift and energy balance

• Crop-by-crop growing protocols

Market Potential

Target segment:

• Fresh vegetables, leafy greens and herbs — about 20% of the food basket by volume and most of its vitamins

Addressable role:

• Can cover the bulk of a city's or region's fresh-produce demand, grown locally year-round

• Does not replace staple grains (~half of human calories), which stay in the field

• Complementary infrastructure that produces food where conventional methods cannot

Typical Project Economics

Commercial unit: 10 modules on ≤400 m² footprint

Capacity: 63.7–252.7 t/year

Crops: high-value greens, herbs, vegetables, berries, seedlings, medical cannabis

Energy: low specific demand (~0.72 kWh/t), powered by ARBOK's own generation — cheaper than solar and 24/7

Water: closed loop, makeup only

Payback: from under 4 months (maximum yield) to ~2.2 years (conservative); ~2.4 years with full renewable autonomy

CAPEX: variable by scale and by vacuum/energy configuration

Risk Factors

Technology and validation:

• TRL 4 — prototype and integrated pilot farm validation still required

• Combined yield uplift and energy balance must be field-verified

• Crop-by-crop growing protocols need development and testing

Market and competitive:

• High initial CAPEX; payback is sensitive to crop price and yield assumptions

• Vertical farming and other CEA technologies are advancing; competitive differentiation depends on cost and energy source

• Market acceptance of locally grown produce varies by region and crop

Operational:

• Sealed, pressure-critical equipment requires maintenance expertise

• Vacuum-tight integrity must be monitored and maintained; one seal failure can degrade yields

• AI and sensor network add complexity; farm-level expertise and remote support critical

Regulatory:

• Food safety certification and organic status (if applicable) depend on country and crop

• Pesticide-free claims require documentation and auditing

• Energy source (renewable, grid, on-site ARBOK generation) affects environmental claims

Supply chain:

• Container-scale deployment depends on reliable supply of reinforced containers and vacuum/gas equipment

• ARBOK ecosystem (Puri, Trinity, ALB) must be available and integrated; single-vendor dependence
