How to Use This Calculator
  1. Enter the number of trays you are growing simultaneously and the tray size in inches (standard is 10×10 or 10×20).
  2. Enter seed density in grams per tray — a standard 10×20 tray typically uses 1 oz (28 g) of seed.
  3. Select your variety: 1=Sunflower, 2=Pea shoots, 3=Radish, 4=Broccoli — each has a different yield ratio and days to harvest.
  4. Review Total Harvest Weight (oz), Days to Harvest, and Yield per Tray to plan your production schedule.
  5. Use Seed Cost per Oz Harvested to evaluate profitability if selling at market.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Number of Trays = 4, Tray Size (side length) = 10, Seed Density per Tray = 28, Variety = 3 = 4 input(s) provided
  2. Calculate Total Harvest Weight
    Total Harvest Weight
    10.08 = 10.08
  3. Calculate Days to Harvest
    Days to Harvest
    7 = 7
  4. Calculate Yield per Tray
    Yield per Tray
    2.52 = 2.52
