Crop Cycle Planning at 11% sanitation and changeover allowance: a worked example

Suppose sanitation and changeover allowance falls to 11%. This page works the full calculation at that level so you can see exactly which result moves and by how much. Estimate days to seed, transplant, or process a planned tray count through a propagation room, NFT channel, or vertical rack so the production planner can sequence sowings against bench availability and harvest dates.

The inputs for this scenario

  • Planned trays to seed or transplant: 480 trays (held at the documented default)
  • Seed line throughput: 60 trays / hour (held at the documented default)
  • Sanitation and changeover allowance: 11 % (the input this scenario stresses; the baseline uses 15)

Working through the calculation

  • The calculation starts from the formula this tool documents: Base seeding/transplant time = planned trays to seed or transplant รท seed line throughput.
  • Required propagation time works out to 8.88 days at these inputs, and this is the headline figure for the scenario.
  • Base seeding/transplant time works out to 8 days at these inputs.
  • Sanitation and changeover allowance works out to 11 % at these inputs.
  • Seed line throughput works out to 60 pieces / min at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where sanitation and changeover allowance sits at 15% and the headline result is 9.2 days, this scenario comes in 3.48% below the baseline at 8.88 days.
  • It computes required propagation time by taking the base seeding time from trays and throughput, then inflating it for a sanitation and changeover allowance. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.

Results at a glance

  • Required propagation time: 8.88 days (headline result)
  • Base seeding/transplant time: 8 days
  • Sanitation and changeover allowance: 11 %
  • Seed line throughput: 60 pieces / min
