Cultivation plan

Cultivation Plan is the set of helpers on each grow-space device that tell TendrilGrow (and the AI advisor) what you are growing and how. Fill them the same week you add the integration — they matter more than a perfect sensor map.

Growth Stage

Persisted snake_case values with human-readable labels in the UI:

seedling → mother → clone → vegetative → early_flower → mid_flower → late_flower → flush → harvest → dry → cure → ready

Default is vegetative. Mothers stay on mother indefinitely. ready is terminal (packaged / stored).

AI objectives change with stage: mothers (structure), clones (rooting), flower (quality), dry/cure (moisture), not “make it look like mid-flower.”

Stage Started and Week In Stage

Entity Domain You edit?
Stage Started date Yes
Week In Stage sensor (weeks, one decimal) No — computed

Week In Stage = days since Stage Started ÷ 7.

Example: Stage Started 2026-08-18, today 2026-09-01 → 14 days → 2.0 wk.

Changing Growth Stage sets Stage Started to today. If you flipped the tent three days ago and then remembered to change the select, open Stage Started and pick that date.

On upgrade from the old Week In Stage number, week 2 becomes a start date about 14 days ago.

These values drive:

  • AI feeding week (GH FloraSeries bands, etc.)
  • Stage projection (days left, projected harvest / ready)
  • Grow Timeline calendar events

Makeup water

Water Type: tap, ro, filtered, bottled, rain, well, distilled, spring, mixed. Default tap.

Used when the advisor talks about fills and flushes — not a live TDS probe.

Targets and inventory

Helper Typical RDWC veg
Sites / Plants 4
Total System Volume gallons of the whole loop
Target pH 5.8–6.0
Target EC mix-to, e.g. 1.6
Feed Interval days between reservoir adjustments
Lights On photoperiod hours (DLI uses this)
Runoff Target coco/soil; ignore in RDWC if unused
Strain / Genetics text
Nutrient Line e.g. General Hydroponics FloraSeries
Base Nutrients products in the three-part / cal-mag / silica set
Additives biologicals, enzymes — list Hydroguard here for live RDWC

Mix order (feeding card)

When Nutrient Line / Base Nutrients look like GH FloraSeries, the AI Feeding Schedule markdown is expanded into a numbered mix order:

  1. Armor Si (in water first)
  2. CALiMAGic
  3. FloraMicro
  4. FloraGro
  5. FloraBloom
  6. Hydroguard last among additives (not with oxidizers)
  7. pH last

Keep Hydroguard out of the same reservoir as H₂O₂, HOCl, or UC Roots.

Dashboard

See Quick start for an entities card and Dashboards for the full tab. Entity IDs follow the grow space name, matching Growth Stage (for example date.clone_stage_started when the select is select.clone_growth_stage).
