Box4Grow started in 2016 when founder Greg Payne (a licensed cultivator managing multiple flowering rooms in New York) couldn’t find a single contractor who understood cannabis cultivation requirements. Every quote came back with 12-18 month timelines, change orders that doubled costs, and HVAC systems designed for offices, not flowering canopies.
So he built his own facility. Then another cultivator asked him to build one. Then ten more.
Today, Box4Grow has delivered over 400 modular grow rooms and complete cultivation campuses to licensed operators from Maine to California. Every system we engineer reflects real-world growing experience: environmental precision cannabis demands, workflow efficiency profitability requires, and compliance state inspectors expect.
“We’re not contractors who learned about cannabis last year. We’re growers who learned to engineer what we needed when nothing else existed.”
Flat-pack grow room panels that connect to create any configuration. Start with one veg and one flower room, add four more next year. No demolition, no downtime; just clip in additional capacity as your license and market demand grows.
Retrofitted 20' and 40' shipping containers arrive as complete grow environments. Integrated HVAC, full-spectrum LEDs, fertigation, automation; delivered to your site, operational in 48 hours. Perfect for space-constrained locations and rapid deployment.
Multi-room cultivation campuses with propagation, vegetative, flowering, drying, curing, and processing rooms. We design workflow-optimized layouts that maximize canopy efficiency while meeting state compliance requirements. From license approval to first harvest in 16 weeks.
Purpose-built modules with precision temperature and humidity control. Protect your harvest quality and maximize terpene preservation with dedicated post-harvest infrastructure designed specifically for cannabis; not generic HVAC retrofits.
From single-room microbusinesses to 20,000 sq ft commercial operations
Cultivators, engineers, and installation specialists who’ve deployed over 400 facilities
Traditional grow facility construction averages $250-$650 per square foot and takes 12-18 months, plus inevitable change orders that add 20-30% to final costs. That’s 12-18 months of lost revenue while you’re paying rent, insurance, and salaries with zero canopy producing.
Box4Grow eliminates that problem. Our modular systems deploy in 12 weeks at half the cost of traditional construction. You get fixed pricing with no surprise change orders, engineered systems designed by growers who’ve managed commercial canopies, and installation teams who’ve deployed hundreds of facilities without missing a deadline.
We’re not the cheapest option. We’re the fastest path to revenue for commercial cultivators who understand that time is money.
How we operate, what we commit to, and why growers trust us
We design facilities based on real cultivation experience. Every environmental spec, lighting layout, and workflow decision reflects hands-on growing knowledge, not assumptions from contractors who've never managed a flowering cycle.
Twelve-week deployment is our standard timeline. We understand that every month of construction delay costs $30K-$60K in lost revenue for a microbusiness operation. We engineer, manufacture, and install faster than anyone because we know time is money.
Start with one room, add ten more next year without shutting down production. Every Box4Grow facility is designed for modular expansion; clip in additional capacity as your license grows without demolition, downtime, or full rebuilds.
The quote you approve is what you pay. No change orders, no surprise costs, no scope creep. Traditional construction averages 20-30% over budget; Box4Grow delivers fixed-price contracts that protect your capital and timeline.

Box4Grow was founded in 2016 by Greg Payne, a New York cannabis cultivator who couldn’t find contractors who understood commercial cultivation requirements. After managing multiple flowering rooms and dealing with 18-month construction timelines that didn’t deliver what growers actually need, Greg built the first modular grow room prototype for his own operation.
Other licensed cultivators saw it and wanted the same solution. What started as one frustrated grower solving his own problem has become the leading modular cannabis facility manufacturer in the Northeast, with over 400 deployments across nine states.
Traditional contractors design facilities based on generic commercial HVAC formulas. We design based on real cannabis growing experience. Our founder managed vegetative rooms, flowering cycles, and post-harvest operations before ever engineering a facility.
The difference shows up in details traditional contractors miss: airflow patterns that prevent hotspots, dehumidification capacity sized for flowering transpiration rates, and lighting layouts optimized for canopy penetration; not just lumens per square foot.
We’re cannabis infrastructure specialists, not general contractors who added “grow rooms” to their service list last year.
We’re headquartered in 521 Fifth Avenue, New York. We serve licensed cannabis cultivators across the United States, with concentrated experience in East Coast markets: New York modular grow rooms, New Jersey cannabis facilities, Connecticut, Massachusetts, Maryland, Ohio, Delaware, Maine, and Florida.
We’ve deployed over 400 prefab cannabis grow rooms for microbusinesses, craft cultivators, and commercial-scale operators. If you hold a cultivation license anywhere in the continental US, we can engineer, manufacture, deliver, and install your facility.
Our team combines hands-on cannabis cultivation expertise with engineering precision. Founder Greg Payne brings 30+ years of infrastructure project management (KPMG, Shell, Dell, Vodafone) plus direct commercial growing experience. VP of Operations Colleen Bates has 15+ years managing complex construction projects in NYC.
We’ve expanded beyond just 5 people, our team now includes cultivation systems designers, installation managers, and technical support specialists who’ve collectively deployed hundreds of turnkey grow facilities. We’re not a corporate team that learned about cannabis from YouTube. We’re growers and engineers who’ve been in the industry since before it was federally trendy.
No. We started with shipping container grow rooms in 2016 (retrofitted 20′ and 40′ containers), but we’ve evolved significantly. Today we offer:
The “Box” in Box4Grow refers to modular construction methodology; not just shipping containers. We build whatever scalable cultivation infrastructure your license and business model require.
Modular construction is inherently more sustainable than traditional building. Prefabricated grow facilities generate 60-80% less on-site waste, reduce construction vehicle emissions, and use recyclable materials (including shipping containers that would otherwise sit in ports).
We partner with Ecologi to offset our carbon footprint—planting trees for every facility deployed and tracking environmental impact. We also design energy-efficient systems: LED lighting that reduces power consumption by 40% vs HPS, optimized HVAC that minimizes energy waste, and closed-loop irrigation that conserves water.

Not at all. We serve everyone from microbusiness cannabis growers with 2,500 sq ft canopy limits to commercial operators scaling to 20,000+ sq ft. In fact, roughly 70% of our clients are microbusinesses and craft cultivators.
Modular construction makes premium cultivation infrastructure accessible at every scale. You can start with a single 10′ grow room (under $40K) or build a complete multi-room facility. The same engineering precision, compliance-ready design, and 12-week deployment applies whether you’re spending $35K or $350K.
We built Box4Grow for growers at every level; not just deep-pocketed MSOs.
