Greenhouse, Indoor Farming & Agri-Processing calculator

Crop cycle planning calculator

Estimate days needed to clear a planned tray count through a propagation room, NFT channel, or vertical rack by dividing planned trays by the line's seeding or transplant rate, then padding for setup, sanitation, and changeover. Use the result to confirm the sow plan fits before benches need to flip to the next crop.

What this calculator does

  • 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.
  • Use it when laying out next month's sow plan, sizing how long propagation will tie up the seed line, or checking whether a new cultivar's longer cycle still fits the rack rotation.
  • Turns planned trays to seed or transplant, seed line throughput, sanitation and changeover allowance into a adjusted run time for crop cycle planning in greenhouse, indoor farming and agri-processing.

Formula used

  • Base seeding/transplant time = planned trays to seed or transplant ÷ seed line throughput
  • Required propagation time = base seeding/transplant time × sanitation and changeover allowance

Inputs explained

  • Planned trays to seed or transplant: Sum trays across cultivars that must clear propagation in this cycle (1020 trays, plug trays, raft boards, etc.).
  • Seed line throughput: Use measured trays per hour by your seeder or transplant crew (e.g., 60 trays/hr per seed line, 25 trays/hr per transplant operator).
  • Sanitation and changeover allowance: Pad for cultivar changeover, seed changes, sanitation between batches, and biosecurity flushes — usually 10-25%.

How to use the result

  • Reach for it when a customer asks for a lead time and you need a number you can defend in 30 seconds.
  • Setup, changeover, and major stoppages are not in the formula. Add them on top for greenhouse, indoor farming and agri-processing jobs that include them.

Common questions

  • What does the crop cycle planning calculator give me? 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. You get a adjusted run time you can defend before quoting, scheduling, or sign-off.
  • Which assumptions drive the adjusted run time? planned trays to seed or transplant, seed line throughput, sanitation and changeover allowance usually move the adjusted run time most. Pull from measured greenhouse, indoor farming and agri-processing runs, supplier data, and recent quotes rather than memory.
  • What do I do with this number? Use it to quote lead time for greenhouse, indoor farming and agri-processing jobs and to push back on requests that do not fit the floor.
  • What should I double-check before acting? Confirm the rate against a recent shift report, not the spec sheet, and account for changeover and setup that the calculator does not.
