AI Greenhouse Lessons Learned
A curated operations playbook distilled from Verdify’s planner lesson table. The public page leads with durable greenhouse knowledge; noisy machine extraction rows stay out of the reading path.
This generated page owns durable lesson wording. Scorecards, plan mechanics, and per-parameter evidence stay on their canonical pages.
Operating Priorities
- Gas heat is 3.9x cheaper per BTU than electric for sustained cold.
- Direct relay control stays in firmware.
- Shade cloth, not software, is the missing hot-day fix.
- VPD is the dominant spring constraint.
- Stale plans must be replaced when forecast regime changes.
Those lessons constrain the bounded control surface listed in AI Tunables Traceability.

Operational Playbook
These are the operating rules the AI planning agent should read first. They are curated from validated lessons; machine extraction details are intentionally pushed into audit tables.
Heat With Gas; Let Thermal Mass Work
- Use electric heat for mild dips and gas heat for sustained cold; gas remains the efficient overnight BTU source.
- Do not chase every spring-morning cold-stress hour with higher heat setpoints. Some score loss comes from crop-band alignment, not plant danger.
- Plan around a 62-66F overnight equilibrium on 48-55F spring nights, especially when humidity can sag VPD below band before dawn.
Evidence: lesson 2 (High, 13x), lesson 91 (High, 6x), lesson 96 (Medium, 1x), lesson 87 (Medium, 2x).
Cooling Is Physics-Limited
- Shade cloth is the real hot-day fix; software can pre-cool, mist, and ventilate, but cannot erase 90F+ solar gain.
- Do not seal the house for humidity trapping when indoor temperature is near the safety ceiling.
- VENTILATE plus misting is the safe outcome when sealed misting cannot overcome solar load.
Evidence: lesson 4 (High, 9x), lesson 89 (High, 6x), lesson 95 (High, 7x).
Tune Misting To Weather Regime
- Reserve aggressive misting for warm, dry, high-VPD days. Cold-dry air can still produce manageable indoor VPD.
- Use moderate mist/fog settings on moderate-dry days to avoid VPD-low overshoot.
- On cool, cloudy, high-RH days, suppress mist and favor ventilation/dehumidification rather than water-use optimization alone.
- Treat the 900s closed-vent experiment as an extreme-dry tool, not a general humidity strategy.
Evidence: lesson 1 (Medium, 9x), lesson 10 (Medium, 4x), lesson 27 (Medium, 10x), lesson 88 (Medium, 4x), lesson 90, lesson 93 (Medium, 1x), lesson 98 (Medium, 8x), lesson 99 (High, 8x), lesson 100, lesson 101, lesson 102 (Medium, 1x).
Keep Planner Control Bounded
- Use canonical DB parameter names; ESP32 object IDs create duplicate active-plan rows.
- Never set timer parameters to zero. Firmware minimums exist to avoid relay chatter.
- Do not push unconfirmed zone-specific VPD targets. Use firmware-confirmed global misting tunables instead.
- Replace stale plans when the forecast regime changes, even if the original plan window has not expired.
Evidence: lesson 5 (High, 3x), lesson 7 (High, 11x), lesson 8 (High, 7x), lesson 94 (High, 1x), lesson 97 (Medium, 1x).
Read Scores Through Structural Constraints
- Some cold, heat, and combined compliance loss is structural when crop bands are narrower than the greenhouse’s spring operating envelope.
- Use VPD compliance as the meaningful optimization axis on warm spring days where low temperature compliance is physically unreachable.
- Separate controller failures from crop-band scoring artifacts before changing tunables.
Evidence: lesson 87 (Medium, 2x), lesson 91 (High, 6x), lesson 92 (Medium, 3x).

Lesson Lifecycle
- Hypothesis — Planner proposes a theory during a planning cycle
- Test — Specific setpoint changes are made with measurable expected outcomes
- Validate — Next cycle scores the result (1–10) and extracts findings
- Graduate — If finding is significant, it’s added to this page at confidence “low”
- Confirm — Each re-validation bumps confidence (low → medium at 3×, high at 5×)
- Supersede — If a better approach is found, old lesson is marked superseded
