Agronomic Read

Local horticulture fallback: interpret the crop as a combined climate-root-zone-behavior system, and challenge stale metadata whenever the biological signal says the room is still active.

Critical Issues

  • POWR 3 / Zone 9b - Top — soil moist below target (2.30 %)
  • POWR 3 / Zone 9b - Top — pore ec below target (0.00 mS/cm)
  • POWR 4 / Zone 1 — soil moist below target (0.60 %)
  • POWR 4 / Zone 1 — pore ec below target (0.00 mS/cm)
  • POWR 4 / Zone 2 — soil moist below target (1.40 %)
  • POWR 4 / Zone 3 — soil moist below target (1.20 %)
  • POWR 4 / Zone 3 — pore ec below target (0.00 mS/cm)
  • POWR 4 / Zone 4 — soil moist below target (0.20 %)

Warnings

  • POWR 1 / Zone 1 - Bottom — soil moist below target (29.70 %)
  • POWR 1 / Zone 1 - Bottom — soil temp above target (82.00 F)
  • POWR 1 / Zone 2 - Bottom — soil moist below target (36.90 %)
  • POWR 1 / Zone 2 - Bottom — soil temp above target (83.20 F)
  • POWR 1 / Zone 3 - Bottom — soil moist below target (26.80 %)
  • POWR 1 / Zone 3 - Bottom — co2 below target (67.70 ppm)
  • POWR 1 / Zone 3 - Bottom — soil temp above target (82.40 F)
  • POWR 1 / Zone 3 - Bottom — rel hum above target (80.00 %)

Occupancy Inference

  • POWR 1 — likely planted despite stale metadata — VWC is still in a biologically believable range at 49.1%; root-zone EC remains active at 4.81
  • POWR 2 — likely planted despite stale metadata — VWC is still in a biologically believable range at 52.8%; root-zone EC remains active at 4.86
  • POWR 3 — likely planted despite stale metadata — VWC is still in a biologically believable range at 46.1%; root-zone EC remains active at 5.86
  • POWR 4 — transitional / verify occupancy — VPD sits in a plausible crop-control range at 1.17 kPa; temperature is running like a conditioned crop room at 73.9F
  • Veg Room — likely planted despite stale metadata — VWC is still in a biologically believable range at 36.2%; root-zone EC remains active at 4.31
  • Dry 1 — transitional / verify occupancy — VPD sits in a plausible crop-control range at 1.09 kPa; temperature is running like a conditioned crop room at 69.7F
  • Dry 2 — likely inactive or insufficient data — VPD sits in a plausible crop-control range at 0.78 kPa
  • Vault — likely inactive or insufficient data — VPD sits in a plausible crop-control range at 0.77 kPa
  • Cure — transitional / verify occupancy — VPD sits in a plausible crop-control range at 0.93 kPa; temperature is running like a conditioned crop room at 65.3F

Teach The Crop

  • A widening drip-to-drain or root-zone EC gap usually means the crop is concentrating salts faster than the current irrigation pattern is clearing them.
  • Climate can quietly undo steering intent; a low-VPD or low-DIF room can feel safe while still limiting the transpirational pull needed to match the root-zone program.
  • Room-turn metadata can lag reality; POWR 1, POWR 2, POWR 3 still read as biologically active, so occupancy should be inferred from the crop signal when labels are stale.

Assumptions To Challenge

  • Instead of asking whether EC is simply high, ask whether the plant is being asked to do too much osmotic work between shots.
  • Do not treat soft climate and aggressive root-zone signals as separate problems; the crop experiences them as one combined steering message.
  • A harvested or missing group does not prove the room is empty if VWC, EC, climate, and irrigation behavior still look plant-driven.

Coaching Questions

  • Does the current runoff strategy intentionally maintain this EC gradient, or is it a side effect of under-clearing the slab?
  • If VPD and DIF are soft, is the team expecting the irrigation program alone to carry the steering load?
  • If a room looks occupied in the data but not in the metadata, what operational decisions are being missed because everyone trusts the label first?
