Modular Cultivation Facilities Built for Commercial Growers

Cannabis Grow Box Solutions

Prefabricated grow rooms, shipping container conversions, and complete cultivation facilities deployed in less than 12 weeks. From 75 sq ft microbusiness setups to multi-room commercial operations.

Turnkey Cannabis Grow Boxes Engineered for Yield, Compliance & Scalability

If you’re searching for cannabis grow containers, shipping container grow rooms, or modular cultivation facilities, you already know the challenge: traditional construction takes 12-18 months, runs 20% over budget, and delays your revenue by nearly a year. For every month your facility isn’t operational, that’s $30,000-$60,000 in lost cultivation revenue.

Whether you need a single weed grow container for a microbusiness operation or a complete multi-room facility with flowering, vegetative, and drying capacity, our cultivation grow boxes deploy in 8-12 weeks with fixed pricing and zero change orders.

Understanding Modular Cultivation Infrastructure

What Is a Cannabis Grow Box?

A cannabis grow box (also called a cultivation grow box, marijuana grow box, or shipping container grow room) is a prefabricated, climate-controlled growing environment designed specifically for commercial cannabis cultivation.  Unlike DIY grow boxes or home grow setups, commercial cannabis grow containers are engineered with industrial-grade HVAC systems, automated environmental controls, and the structural integrity to meet state building codes and cultivation regulations.

The Evolution from DIY to Commercial

While hobbyist growers might use small weed grow boxes or grow cabinets for personal cultivation, licensed commercial cultivators require professional-grade infrastructure. Modern modular grow rooms and shipping container grow facilities provide:

40-Foot Commercial Grow Boxes

  • Best for: Large-scale cultivators, multi-room facilities, commercial flower rooms

Our 40-foot weed grow containers provide approximately 300 sq ft of canopy in a single unit—deploy multiple rooms to create facilities exceeding 10,000 sq ft. Commercial cannabis cultivation boxes include:

  • Industrial-grade HVAC systems (multi-ton capacity)
  • Advanced dehumidification (150-200 pints/day)
  • Heavy-duty electrical infrastructure (240V, 150+ amp service)
  • Structural engineering for stacked or connected configurations

Shipping Container Grow Room or Modular Construction?

Understand Your Options

Shipping Container Conversions

Cannabis shipping container grow rooms use retrofit 20' or 40' ISO shipping containers as the structural shell. Benefits include:

Best for cultivators prioritizing security, mobile operations, or urban locations with limited traditional construction options.

Modular Grow Room Construction

Modular cannabis grow boxes use insulated panel construction (similar to walk-in coolers) with structural framing. Advantages include:

Ideal for commercial cultivators building permanent facilities with plans to scale from 5,000 sq ft to 20,000+ sq ft over multiple years.

Complete Cannabis Cultivation Solutions for Commercial Growers

From single grow boxes to multi-room facilities; modular infrastructure engineered for speed, compliance, and scalable cannabis production.

Beyond Grow Boxes: Complete Cannabis Cultivation Facilities

Integrated infrastructure for every stage of commercial cannabis production

Drying & Curing Rooms

Post-harvest processing is where amateur operations lose quality and commercial cultivators maximize value. Our cannabis drying rooms provide:

Precision Humidity Control

58-62% RH for optimal terpene retention throughout the drying cycle

Temperature Stability

60-65°F throughout cure cycle with automated climate management

Dri-Flower Hanging Rack Systems

Commercial throughput capacity with optimized airflow patterns

Programmable Curing Stages

Touchscreen controls for custom cure profiles and stage automation

Air Filtration & Monitoring

Environmental monitoring with real-time data logging and alerts

Protect your harvest quality and compliance – improper drying creates mold risk, regulatory failures, and lost revenue.

Multi-Room Cultivation Campuses

Licensed cultivators building new facilities need more than individual grow boxes. Our complete cultivation infrastructure includes:

Propagation Rooms

Cloning and seedling environments with high-humidity zoning and T5/LED propagation lighting

Vegetative Rooms

18/6 light cycles optimized for canopy development and plant structural growth

Flowering Rooms

12/12 photoperiod with enhanced HVAC for flower density and terpene production

Drying Facilities

Post-harvest processing with precision humidity control and commercial rack systems

Processing Areas

Trimming, packaging, and QA/QC workflows with compliance-ready documentation systems

We design room sequences and environmental zoning to match your cultivation methodology, whether you're running perpetual harvest schedules or batch production cycles.

The Box4Grow Advantage: Built by Growers, For Growers

Why commercial cultivators choose modular over traditional construction

Designed by Licensed Cultivators

Most contractors build walls. We design for canopy efficiency, workflow optimization, and the environmental precision cannabis demands. Founder Greg Payne is a licensed cultivator—every detail is engineered by someone who's actually grown commercially.

Details that matter: Dehumidifier drain placement, light mounting systems, door swing direction, airflow patterns, and fertigation access points.

12-Week Deployment vs 12-Month Construction

While traditional builds wait on permits, subcontractors, and change orders, you're harvesting in 90 days. Our manufacturing process eliminates:

  • Permitting delays (modular structures often exempt from traditional building permits)
  • Weather-related construction delays
  • Contractor coordination failures
  • Material shortage disruptions
Every week of delay costs $7,500-$15,000 in lost revenue for a 5,000 sq ft operation. Our fixed deployment timeline means predictable cash flow and faster ROI.

Fixed Pricing, Zero Surprises

Traditional construction change orders average 15-20% budget overruns. Our pricing includes everything: materials, labor, delivery, installation, and startup support.

The quote you approve is what you pay. No hidden costs, no change orders, no budget surprises.

Scalability Without Shutdown

Expanding a traditional facility means months of construction chaos and lost production. Add modular grow rooms without disrupting active grows—connect new units to existing infrastructure, maintain revenue during expansion.

Scale from 2 rooms to 20 rooms without shutting down a single grow cycle or losing harvest revenue.
