The run report and its grade

What the brain freezes when you log a harvest, how yield is normalised, and what the execution grade does and does not judge.

When it appears

Log a Harvest entry on a plant (wet and/or dry weight) and the plant's journal gets a Run report card. The dry weight usually comes days later — log it on another Harvest entry and the yield numbers update; the evidence does not change unless you press Re-capture evidence on the card (useful only while the run is still inside history retention). Delete the only Harvest entry and the report goes with it.

Yield, normalised

Number From
g/m² dry weight ÷ (zone canopy m² ÷ plants in the zone). Canopy area is set per zone in Settings › Zones.
g/W dry weight ÷ (photoperiod lamp watts ÷ plants)
g/kWh dry weight ÷ light energy share — lamp watts × recorded light hours (12 h a day assumed when none were recorded); dim % is assumed 100 % where the hub cannot read it
g/mol dry weight ÷ cumulative mol on the plant's canopy share, from the zone's daily DLI estimate
Flip → harvest calendar days, next to the catalog's flowering window for the strain

Energy, DLI and mol are estimates and say so. Anything missing (no canopy area, no dry weight) is listed on the card instead of shown as zero.

The evidence and the grade

At the first Harvest entry the brain freezes, from flip (or sprout) to harvest: VPD time in band against the zone's recorded target at each moment, DLI days in the stage target (judged against the generic flower band, which follows the CO₂ setting — see Plants, stages, harvest window and DLI), Probe reading without faults (fault minutes) and Dryback within the P2 limit.

The grade (A+ to F) scores execution — how well the room held its targets — never the yield, which depends on the strain. Weights: VPD 35 %, DLI 30 %, probe 20 %, dryback 15 %. A part with under three days of data is left out and the rest re-weighted; the card shows every part, its weight and the evidence line behind it.

Longer than history

Raw sensor history is kept 45 days by default. Every day the brain condenses each finished day into a few evidence numbers per zone and per probe and keeps those indefinitely, so a flower run longer than 45 days is still graded on the whole run. The card says how many days came from the daily roll-up.

Comparing runs

The report compares with your own earlier runs of the same strain (dry g, g/m², g/W, grade, and this run against their mean). Caniya Growers' published yield tiers appear only as a labelled secondary reference. The same numbers fill the g/W column on the strain's page in CannaLib.
