How to Use This Calculator
  1. Enter your greenhouse interior length and width in feet, along with the desired bench width and aisle width.
  2. Set the end clearance in feet for doors and equipment access, then choose a bench layout (Peninsula or Longitudinal).
  3. Review Bench Count, Total Bench Area (sq ft), Space Efficiency (%), and Estimated Plant Capacity.
  4. Adjust bench width or aisle width to optimize the Space Efficiency percentage for your crops and workflow.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Greenhouse Length = 96, Greenhouse Width = 30, Bench Width = 5, Aisle Width = 3 = 6 input(s) provided
  2. Calculate Number of Benches
    Number of Benches
    4 = 4
  3. Calculate Total Bench Area
    Total Bench Area
    1800 = 1800
  4. Calculate Total Floor Area
    Total Floor Area
    2880 = 2880
  5. Calculate Space Efficiency
    Space Efficiency
    62.5 = 62.5
