A framework for evaluating the topic
Planning note: More tiers do not automatically mean more usable capacity; crop height, lighting distance and maintenance access set limits.
Coordinate rack dimensions, tier spacing, service aisles, structural load, airflow and utility access with the growing system. This resource provides general technical information. Final capacity, equipment and implementation choices require engineering calculations based on site and project data.
Clear tier spacing is obtained after allowing for mature crop height, channel or tray depth, luminaire working distance and maintenance clearance.
Rack loading includes water in channels, crop mass and maintenance live loads rather than dry equipment alone.
Aisles are tested against harvest carts, sanitation and emergency access; pipe falls and cable routes are not left to residual space.
Topics covered in technical assessment
Mature crop and equipment height
Clear tier spacing is obtained after allowing for mature crop height, channel or tray depth, luminaire working distance and maintenance clearance.
Luminaire working distance
Rack loading includes water in channels, crop mass and maintenance live loads rather than dry equipment alone.
Rack load and anchorage
Aisles are tested against harvest carts, sanitation and emergency access; pipe falls and cable routes are not left to residual space.
Aisle, harvest and sanitation access
Clear tier spacing is obtained after allowing for mature crop height, channel or tray depth, luminaire working distance and maintenance clearance.
Air distribution between tiers
Rack loading includes water in channels, crop mass and maintenance live loads rather than dry equipment alone.
Supply and return pipe gradients
Aisles are tested against harvest carts, sanitation and emergency access; pipe falls and cable routes are not left to residual space.
Cable tray and driver placement
Clear tier spacing is obtained after allowing for mature crop height, channel or tray depth, luminaire working distance and maintenance clearance.
Fire, egress and maintenance clearances
Rack loading includes water in channels, crop mass and maintenance live loads rather than dry equipment alone.
Planning and comparison logic
Coordinate rack dimensions, tier spacing, service aisles, structural load, airflow and utility access with the growing system.
