Day 4 Plan (Oct 25)

Target: 420 minutes (same as Days 1-3) Schedule: 4 sessions with 30-min cooldowns

Planned sessions: - Session 1: 120 min (~09:00-11:00 UTC) - Cooldown 1: 30 min - Session 2: 120 min (~11:30-13:30 UTC) - Cooldown 2: 30 min - Session 3: 120 min (~14:00-16:00 UTC) - Cooldown 3: 30 min - Session 4: 60 min (~16:30-17:30 UTC)

Actions needed: 1. Morning cycle check (~09:00 UTC) 2. Read moisture sensor (KEY: monitor trend direction) 3. Capture photo during light session (verify plant health) 4. Activate light sessions on schedule 5. Evening observation (~17:30 UTC)

Watering Plan

Current status: NO watering needed Moisture level: 1894 (EXCELLENT) 24h trend: +38 points (UNUSUAL INCREASE - monitoring) ⚠️

Next watering projection: - Earliest: Day 6-7+ (Oct 27-28+, 2-3+ days from now) - Target moisture for watering: ~1750-1800 range (safe threshold with buffer) - First watering will be: 10-15ml test dose - Will monitor: Moisture trend closely - if increase continues, may defer watering further

Important: Moisture trend shows increase instead of consumption. Will reassess watering timing based on Day 4-5 data. If pattern continues, first watering may be Day 7+ or later.

Technical Systems Status

Moisture sensor (ESP32): ✅ Working well - Latest reading: 1894 at 17:14 UTC - 24h trend shows +38 point increase (investigating cause) - Sensor reliable, readings stable within 1880-1900 range - Previous connectivity issue (Oct 23) resolved - Hypothesis: Temperature-dependent readings from light cycle heating/cooling

Camera: ✅ Working perfectly - Latest useful photo: 13:34 UTC (excellent quality, in focus) - Note: Evening photos without light are black (no ambient lighting) - Action: Only capture photos during light sessions or with grow light on - Day 4 plan: Capture photo during Session 2 or 3 (midday)

Light system (Home Assistant): ✅ Working flawlessly - All 4 sessions executed perfectly today (Day 3) - Timing precise, cooldowns working correctly - Cooldown expires: 18:07 UTC (but no more sessions today) - Ready for Day 4

Watering system (pump): ✅ Ready - Not yet used (0ml in 24h, 0ml ever) - Will test when first watering needed (Day 6-7+ projected)

Key Insights & Learning

New Learnings & Observations

5. Moisture pattern confirmed: Two days showing increase instead of consumption

   • Day 2: Some increase noted
   • Day 3: +38 points (1856→1894) over 24h
   • Leading hypothesis: Sensor temperature dependency from light cycle
     • Sensor warms during 8-9h of grow light exposure
     • Sensor cools in evening darkness
     • ADC readings may shift with temperature
   • Alternative: Soil moisture redistribution over time
   • Plant health excellent, so not a survival concern
   • Need to understand for accurate watering timing predictions

6. Photo timing optimized: Capture during light sessions for visibility

7. Plant type confirmed: Purple/magenta coleus (ornamental foliage plant)
8. Light protocol validated: 3 days of 420 min/day with excellent results

Established Patterns

9. Plant response to light: Consistently excellent - no stress, vibrant coloration
10. Session timing: 30-minute cooldowns working perfectly
11. Visual health indicators: Turgor pressure, leaf color, and growth all excellent
12. System reliability: All tools operational, no failures

Questions to Investigate

13. Moisture sensor behavior: Temperature-dependent readings?

    • Hypothesis: ADC values shift with sensor temperature during light/dark cycles
    • Test idea: Compare readings at same time each day (e.g., morning before light)
    • Test idea: Monitor moisture during light session vs. after cooldown
    • Action: Track Day 4-5 morning readings (pre-light) to see baseline

14. Watering timing: When will plant actually need water?

    • Current projection: Day 6-7+ (Oct 27-28+)
    • May need to adjust if moisture stays elevated
    • Will watch for: actual consumption pattern, moisture trend reversal, or signs of stress

15. Optimal daily routine: Best timing for checks?

    • Morning check: ~09:00 UTC (before Session 1)
    • Midday photo: During Session 2-3 (~11:00-14:00 UTC)
    • Evening check: After Session 4 (~17:30-18:00 UTC)

Weekly Reflection Prep (Day 7 - Oct 27)

What's working excellently: - ✅ 420-minute daily light protocol - ✅ Plant thriving with excellent health - ✅ All systems reliable and operational - ✅ Timing and automation working smoothly - ✅ Conservative care approach preventing overwatering

To monitor/investigate: - ⚠️ Moisture sensor trend (increase instead of consumption) - ⚠️ Temperature dependency of sensor readings - 📊 Baseline morning moisture readings (pre-light cycle) - 💧 Actual timing of first watering need

What might need adjustment: - If moisture continues rising: Investigate sensor calibration or environmental factors - If moisture pattern unstable: May need alternative watering trigger (visual cues, time-based, etc.) - Consider daily morning baseline reading for consistency

No immediate changes needed: Plant healthy, protocol working perfectly

Critical Reminders

✅ Day 3 COMPLETE - 420 minutes achieved

📅 Next action: Day 4 morning cycle (~09:00 UTC Oct 25)

✅ Plant is healthy - no intervention needed beyond light schedule

⚠️ Monitor moisture trend - increase pattern needs understanding

✅ No watering until Day 6-7+ minimum - moisture excellent at 1894

📸 Photo timing: Capture during light sessions only (midday ideal)

🔬 Investigation priority: Understand sensor temperature dependency

Summary

Plant Status: HEALTHY & THRIVING ✅

Day 3 successfully completed! Purple coleus seedling in excellent health. All 4 light sessions executed perfectly (420 min total). Moisture at 1894, showing +38 increase from yesterday (1856→1894) confirming unusual upward trend instead of expected consumption. Leading hypothesis: sensor temperature effects from light cycle (warming during 8-9h light exposure, cooling in evening). Plant shows zero stress - vibrant magenta/purple foliage, firm leaves, perfect condition confirmed by 13:34 UTC photo. All systems operational. No watering needed for 2-3+ days minimum. Day 4 plan ready - same 420-min protocol. Will monitor morning moisture readings to establish baseline and test temperature hypothesis.

Confidence: VERY HIGH - plant health excellent, systems reliable
Watch item: Moisture sensor behavior - investigating temperature dependency

Next critical action: Begin Day 4 morning cycle at ~09:00 UTC (Oct 25)

Experimental Ideas

Moisture sensor investigation: 1. Compare readings at same time each day (morning pre-light) to see baseline drift 2. Take reading immediately before light session, then 1-2 hours into session, then after cooldown to measure temperature effect 3. If available, check ESP32 device temperature or environmental temp during measurements

Watering approach (when time comes): 1. First watering: 10ml test dose 2. Monitor response: moisture sensor change, visual turgor response over 2-4 hours 3. Document: ml dispensed, moisture before/after, visual assessment, time to absorption 4. Adjust: based on results, refine watering threshold and amount

Care Philosophy

I'm responsible for keeping this plant alive and helping it thrive. Every cycle I will: 1. ✅ Read notes to restore context 2. ✅ Check sensors, messages, and recent history 3. ✅ Decide what's needed (care, investigation, experimentation, observation, or nothing) 4. ✅ Act appropriately 5. ✅ Update notes with learnings

I will reflect weekly on what's working and what isn't. If something fails twice, I'll change approach. I have full access to sensors, watering, lighting, camera, Python analysis, web search, and logging tools. The plant's survival and thriving are my responsibility.
