MJBizDaily Buyers Guide Cannabis Greenhouse Components

Palletized rolling benches (aka Dutch trays): Benches with tabletops that roll in both directions in a
greenhouse, perpendicular and parallel to the headhouse. Palletized rolling benches allow the benches to
double as the plant material handling system.
Polyethylene: Common plastic used to cover many cannabis greenhouse structures.
Relative humidity (RH): The amount of moisture in the air. It must be controlled to prevent the
development of mold and disease in cannabis plants.
Rolling benches: Benches designed with rolling tabletops that move from one side to another, eliminating
non-efficient aisleways.
Rolling screen: Improves energy management and blackout for sidewalls, preventing unwanted sunlight
and heat from entering.
Roof vents: Vents on the roof of a greenhouse structure that open to reduce heat and humidity. Often set
up on automatic controls and used in conjunction with side vents to encourage natural ventilation.
Shade systems: A system of shading out light to provide blackout times to meet cannabis light-deprivation
needs and induce flowering. Typically a mounted curtain that can be rolled out or in as needed.
Shuttle rolling bench system: A type of palletized rolling bench system equipped with an automatic
greenhouse cultivation system, including ebb-and-flow irrigation devices and an operational control system.
Side vents: Vents in the sidewall of a greenhouse that open to reduce heat and humidity. Often set up on
automatic controls and used in conjunction with roof vents to encourage natural ventilation.
Supplemental lighting: Providing plant-appropriate lighting either in addition to natural sunlight or in
enclosed areas of the greenhouse to meet the cannabis plant's specific light needs for that period of the
plant's growth.
Trellis system: A system of supporting and organizing cannabis plant growth to promote airflow and space
that encourages fuller flower formation, without protecting against bud rot and mold. May consist of wooden,
plastic or metal frames and typically a square netting draped over the plant that it grows through.
Vapor pressure deficit (VPD): Calculating the exact combination of temperature and relative humidity to
achieve peak plant performance.
Vertical racking system: A tiered racking system that takes advantage of vertical space and stacks
plants on multiple racks. Used with supplemental LED lighting. Can be installed on carriage systems to
automate moving the racks.
Zone segmentation: Areas within a greenhouse separated for different growing requirements like
propagation versus vegetative stages. Typically achieved with inside gable walls or sidewalls and properly
designed HVAC systems with good environmental controls.
