Harvest log · Aug–Sept 2026 first-cycle validation

The daily-use instrument for blackout-end, lights-on, and harvest.

This is the log the owner keeps at the bench through the August–September 2026 first-cycle validation. The timing block at the top anchors the seed → blackout → light → harvest schedule across the 7–14 day cycle window. The 9-column log table down the page captures one row per cycle run — cycle number, seed date and variety, blackout start and end, lights-on, harvest date, dry yield per tray, pack-size count, and free-form notes.

Print one copy per cycle run, fill in same-day so blackout-end and lights-on drift don't get reconciled from memory. The cycle summary strip at the bottom is for end-of-run totals across a 10-run baseline.

Target cycle timing · 7–14 day window (Phase 1)
Day Phase Action Check Owner
Days 0–1 Seed → blackout start Saturate seed, stack trays, weight 3–5 lb; cover with blackout dome. No light bleeds. Uniform germination across all trays in the batch. JP
Days 1–3 Blackout Press 3–5 lb weight; no light. Cab stays sealed. Ambient 68–72°F. Cotyledons lifting the weight; even canopy press-curve. JP
Days 3–5 Blackout → light Remove weight when ≥80% of trays show lift; cue lights to 14–16 h photoperiod. Even canopy height ±0.25 in across the batch. JP
Days 5–8 Lights on 14–16 h photoperiod; maintain 65–70°F; airflow on. First true leaves visible; no leggy stretch. JP
Days 7–14 Harvest Cut at first true leaf; weigh dry yield before pack; refrigerate ≤41°F. Yield vs target 1.0–1.4 lb/tray (~454–635 g). JP

Hygiene note: wash hands before each row entry · wipe pen between cycles · do not set the log on the bench where seed or media is handled · cross-reference pack-size count to the /pricing-and-economics.html pack-size table to spot deviation vs baseline.
