Continuous-Harvest Stagger Planner
Plan staggered cycle starts across multiple grow rooms for continuous harvest. The math behind operational cash-flow stability.
Why stagger
A single grow room finishes a crop cycle, harvests, then sits empty during transplant + veg before producing the next harvest. From a cash-flow and labor standpoint this is brutal: you have intense harvest weeks (full revenue, full labor) followed by quiet veg weeks (zero revenue, low labor needs).
Multiple flower rooms staggered by even fractions of the cycle smooth this out. Four rooms with 56-day flower cycles staggered every 14 days produce continuous harvests every two weeks. Eight rooms staggered weekly produce weekly harvests. Cash flow becomes regular; labor needs flatten; storage requirements stabilize; downstream processing (drying, curing, packaging) runs at constant capacity rather than pulsing.
Stagger math
For continuous harvest with N rooms and cycle length C days: stagger_interval = C / N harvests_per_year = 365 / stagger_interval = 365 × N / C For multi-stage cycles (e.g., veg + flower): Veg space is shared (mother room or single veg room can stagger plants for multiple flower rooms) Flower rooms are the constraint — each flower room runs at flower-stage cadence Per flower room: cycles_per_room_per_year = 365 / cycle_total_days Each room contributes a harvest at this rate
Reality checks
| Constraint | How to handle |
|---|---|
| Veg space capacity | Veg room must produce N flower-rooms-worth of plants on the stagger interval. Calculate veg-room plant count carefully. |
| Drying / curing space | Drying takes 14-21 days; curing takes 4-12 weeks. With weekly harvests, you need 2-3 simultaneous drying spaces and 4-12 simultaneous curing storage areas. |
| Trim labor | Trim during week between cycles, or hire dedicated trimmers. Continuous harvest = continuous trim labor. |
| Packaging / lab testing | Per-batch lab testing has a turnaround time (3-7 days). With weekly harvests, lab queue and packaging must keep pace. |
| Cleanup days | Each flower room needs 1-3 cleaning days between cycles. Subtract from "available" room time. Real stagger interval may need to be slightly longer than pure math suggests. |
| Veg shortfall | If veg can't keep up with flower-room appetite, increase veg space or extend cycle. |
Common configurations
| Operation | Cycle | Rooms | Stagger | Pace |
|---|---|---|---|---|
| Hobbyist single room | 63 d | 1 | — | ~6 harvests/year |
| Small commercial | 56 d (flower) | 2 | 28 d | ~13 harvests/year (every 4 weeks) |
| Mid commercial | 56 d | 4 | 14 d | ~26 harvests/year (every 2 weeks) |
| Large commercial | 56 d | 8 | 7 d | ~52 harvests/year (weekly) |
| Industrial | 56 d | 16 | 3.5 d | ~104 harvests/year (twice weekly) |
| Lettuce SOG indoor | 30 d | 4 | 7-8 d | ~52 harvests/year (weekly) |
| Microgreens daily | 14 d | 14 | 1 d | ~365 harvests/year (daily) |
