Cultivators building complete clone-to-cure operations who need integrated drying and curing capacity that matches flowering room harvest cycles without creating bottlenecks.
Precision Vapor Pressure Control - Vaportrol™ technology maintains exact temperature and vapor pressure (dew point) to achieve stable 0.58-0.62 water activity in 4 days. Prevents mold growth while preserving volatile terpenes that evaporate in traditional hang-dry systems.
8-Day Cure vs 21 Days Traditional - Controlled atmosphere curing reduces timeline by 60% compared to conventional methods. Reach stable water activity in 4 days, complete cure in 8 days total. Faster inventory turnover without sacrificing quality.
Integrated Processing Workspace - Complete post-harvest solution includes climate-controlled drying chamber plus adjacent processing area for trimming, bucking, and packaging. Optimize workflow from harvest to jar in one modular system.
Mold is the number one cause of yield loss in commercial cannabis, destroying entire harvests and causing failed lab tests that result in zero revenue. Traditional hang drying in uncontrolled environments creates 60-80% mold risk while allowing valuable terpenes to evaporate at ambient temperatures. Even cultivators who avoid mold often overdry flowers, creating harsh smoke and brittle buds that can't command premium pricing. Box4Grow drying rooms eliminate both catastrophes with precision environmental control.
Botrytis, Alternaria, and other mold species thrive in traditional drying environments where humidity fluctuates and dense buds trap moisture internally. Our Vaportrol™ system maintains precise vapor pressure that eliminates mold conditions while operating at temperatures low enough to preserve volatile monoterpenes. No more choosing between mold risk and terpene loss.
State testing requires specific water activity ranges and microbial limits. Inconsistent drying creates unpredictable results where some batches pass and others fail with no clear cause. Stable 0.58-0.62 aw achieved through precision control means predictable microbial test passes, no surprise batch rejections, and regulatory compliance confidence.
Traditional curing ties up capital for 21-60 days while product sits achieving proper moisture levels. Eight-day cure capability means harvested cannabis reaches sale-ready condition in one-third the time. Faster inventory turns improve cash flow, reduce carrying costs, and allow reinvestment in next production cycle.
Harvest bottlenecks occur when flowering rooms produce more than drying capacity can handle. Modular 20' and 40' units let you scale post-harvest infrastructure to match cultivation output. Add units as production grows without facility shutdown or extensive construction.
Fresh-frozen cannabis retains 92% of volatile terpenes while traditional air drying destroys them through evaporation. Vaportrol™ maintains cool temperatures (60-65°F) and precise vapor pressure to protect the aromatic compounds customers pay premium prices for.
Traditional HVAC swings unpredictably between too fast (harsh smoke, no value) and too slow (mold risk). Our programmable system delivers cultivar-specific drying curves with stable conditions from harvest to cure.
Complete integrated solution includes R13 insulated structure, corrosive-resistant equipment, perforated drying racks, integrated scales, air filtration, and automation. Everything pre-engineered for cannabis environments, not pieced together from generic components.
7-inch touchscreen control interface with 5 unique programmable drying/curing stages. Patent-pending Vaportrol™ technology manages temperature, vapor pressure (dew point), and airflow for pinpoint relative humidity control. App interface with TCP/MODBUS integration and FTP data logging for compliance documentation.
Perforated sheet pans and curing racks on rolling baker's carts for efficient loading. Integrated cart scale with 10-gram resolution tracks real-time water weight loss. Dehumidification, humidification, and ventilation systems work in concert. Air filtration and movement optimize drying consistency throughout chamber.
FRP gloss white panels with R13 insulation rating meet NSF food-grade standards. Corrosive-resistant equipment handles high-moisture cannabis environments long-term. Complete structural isolation from external climate variations. Works consistently in humid coastal areas or dry high-altitude locations.

Why Commercial Cultivators Choose Integrated Systems Over DIY Solutions
Building post-harvest rooms from separate components creates vendor coordination nightmares, incompatible equipment, and months of troubleshooting. Commercial dehumidifiers aren't designed for cannabis moisture loads. Generic HVAC can't maintain vapor pressure precision. Racks and scales are separate purchases requiring installation coordination. Box4Grow delivers complete systems engineered specifically for cannabis post-harvest with everything pre-integrated and tested.
Many cultivators attempt drying with residential dehumidifiers and box fans in repurposed spaces. This works for home growers processing ounces but fails at commercial scale processing pounds. Inconsistent results, unpredictable timelines, and quality variation make production planning impossible. Our pharmaceutical-grade systems deliver 100% consistency whether processing 50 lbs or 500 lbs monthly.
Vaportrol™ manages both temperature and vapor pressure (dew point) simultaneously, which traditional HVAC cannot do. Mold requires specific moisture conditions to grow. By maintaining precise vapor pressure, we eliminate the humidity levels where mold thrives. Simultaneously, cool temperatures (60-65°F) prevent volatile terpenes from evaporating. This dual control solves the traditional dilemma where preventing mold meant running hot/dry conditions that destroyed terpene profiles.
Water activity (aw) measures moisture availability for microbial growth, not just moisture content. Cannabis at 0.58-0.62 aw is dry enough to prevent mold but moist enough to cure properly and preserve terpenes. Below 0.45 aw, buds become brittle and curing stops. Above 0.65 aw, mold risk increases dramatically. Achieving stable aw in this range is the key to both quality and compliance. Our system reaches target aw in 4 days versus 14 days traditional methods.
A 40-foot unit includes both drying chamber and processing workspace. Exact capacity depends on how densely you load racks and your specific drying timeline preferences. The system is designed to match typical harvest volumes from corresponding grow room sizes. For example, if harvesting from a 40′ flowering room every 8-10 weeks, a 40′ drying unit provides appropriate processing capacity. We help calculate your specific needs during consultation based on your cultivation schedule.
Yes. The programmable touchscreen allows you to create and save multiple drying recipes. Dense indica flowers might need slower initial drying than airy sativa buds. High-resin strains require different vapor pressure curves than lower-resin cultivars. You can program up to 5 distinct stages per recipe, save successful protocols, and recall them for future harvests of the same genetics.
Research shows controlled atmosphere curing achieves in 8 days what traditional jar curing takes 21 days to accomplish. The key is reaching stable water activity quickly (4 days) then maintaining precise conditions during cure phase. Many cultivators cure 60-180 days for premium products. Our system doesn’t prevent long cures if desired – it makes them optional rather than mandatory for basic quality. You can achieve sale-ready quality in 8 days or extend curing for ultra-premium positioning.
Units require standard commercial electrical service appropriate to size (specifications provided with each model). The modular containers are weatherproof and can be placed outdoors, in warehouses, or integrated into existing facilities. A 40-foot unit occupies 320 sq ft of floor space (40′ × 8′). Climate-controlled units work in any environment from humid Florida to dry Colorado without performance degradation.
Our drying/curing units work standalone or connect to complete Box4Grow cultivation campuses. Many operators pair a 40′ drying unit with multiple 20′ or 40′ flowering rooms, creating perpetual harvest schedules where one room dries while others flower. The processing workspace included in drying units accommodates trimming and bucking before transfer to curing racks, streamlining post-harvest workflow in one climate-controlled environment.
