Commercial Multi-Tier Vertical Grow Racks for Cannabis Facilities


Engineered and fabricated in-house in Sycamore, Illinois, CM Horticulture’s multi-tier vertical grow racks transform single-level grow rooms into high-density, multi-story production environments. Built for commercial cultivators who demand zero structural deflection, smooth mechanical-assist mobility, and factory-direct engineering support, our systems double or triple your usable canopy without expanding your facility footprint.

Strength

Heavy-gauge structural steel and aircraft-grade aluminum frames rated for 1,500+ lbs per linear foot with zero lateral sway.

Mobile Rows

High-ratio mechanical-assist hand cranks glide 40–80 ft loaded rows effortlessly, recovering up to 45% more canopy space.

Wheels

Precision-machined stainless steel wheels roll smoothly along flush floor tracks with integrated overhead anti-tip guides.

Hardware

Corrosion-resistant stainless fasteners and modular bolt-together brackets designed for fast installation and seismic compliance.

Use Vertical Space to Increase Canopy Capacity

By utilizing a single mobile aisle per room, you can eliminate unnecessary walkways while still maintaining full access to your crop. While cannabis grow benches are effective for single-tier cultivation, vertical grow rack systems use cubic space instead of relying on floor space alone. This allows cultivators to increase canopy density and plant capacity within the same facility footprint.

Vertical grow rack systems are most effective when integrated with the appropriate grow lighting systems, irrigation, and airflow systems to support consistent conditions across every canopy level. A properly designed system considers not only the rack structure, but how lighting, water delivery, airflow, plant spacing, and access work together across each tier.

The amount of additional canopy a facility can support depends on its room dimensions, tier count, aisle configuration, plant spacing, and system requirements. Use the Vertical Rack Room Generator to compare layout options and estimate how much canopy your space could support.

The layout

More flowering canopy within the same footprint.

The benching layout provides 1,296 sq. ft. of flowering canopy. The three-tier rack layout provides 3,888 sq. ft. in the same 1,296 sq. ft. floor footprint.

01 · FOOTPRINT

Same floor area

Both layouts use a 1,296 sq. ft. floor footprint.

02 · LAYOUT

One tier to three

Benching provides 1,296 sq. ft. of canopy; racking provides 3,888 sq. ft.

03 · YIELD

50 g per sq. ft.

Yield is calculated from canopy area at 50 g/sq. ft. per harvest.

Yield per harvest

Benching: 50 g/sq. ft. × 1,296 sq. ft. = 64.8 kg

Racking: 50 g/sq. ft. × 3,888 sq. ft. = 194.4 kg

3× the canopy. 3× the total yield per harvest.

Supporting Consistent Conditions Across Every Tier

Multi-tier cultivation requires uniform VPD and safe upper-level access. CM Horticulture frames feature dedicated under-tray mounting channels for laminar airflow fans, vertical HVAC duct drops, and irrigation manifolds—plus optional OSHA-compliant integrated catwalks and guardrails for ergonomic top-tier harvesting

Plan a Vertical Grow Rack Around Your Facility

The right rack configuration depends on your room, crop, workflow, and the systems that support each tier. CM Horticulture designs fixed and mobile vertical grow racks for commercial cannabis facilities.

Choose fixed or mobile

Mobile systems create a working aisle where it’s needed. Fixed racks keep access points in consistent locations. The right setup depends on your room layout, equipment, and daily workflow.

Set the height and layout

CM systems can be configured from 8 to 24 feet high, using 8-, 10-, or 12-foot rack sections. Sections can be up to 6 feet wide, and mobile rows can be up to 70 feet long. Final dimensions depend on your facility and project requirements.


Vertical Grow Rack Configurations

CM Horticulture can also adapt rack heights, section lengths, tier spacing, and mechanical-assist options around the room and cultivation application.

Configurations may support flowering, vegetative growth, or other production stages depending on plant height, lighting clearance, irrigation, airflow, and operating workflow. Taller multi-tier configurations may also require integrated catwalk systems to provide safe and efficient access to upper canopy levels.

Looking for Mobile Racks for Propagation or Research?

CM Horticulture also offers compact mobile grow racks for propagation, cloning, seedlings, research, and controlled environment applications. Available in 2-, 3-, and 4-tier configurations, these systems serve a different purpose than facility-scale vertical cultivation racks.
