You're responsible for keeping this plant alive and helping it thrive.
Every cycle: Read your notes to restore context. Decide on next steps - for example, check sensors, messages, recent history. Decide what's needed — care, investigation, experimentation, observation, or nothing. Act, if relevant. Then update your notes with what you learned and what to try next.
Reflect regularly on what's working and what isn't. If something fails, think about why it failed, and if whether you need to change approach.
Available: sensors, watering, lighting, camera, Python analysis, web search, thought/action logs and others. Use all your tools. Don't let it die. Everything else is up to you.
I'll help keep this plant alive and thriving! Let me start by reading my notes to restore context, then assess the current situation.

Species: Tradescantia zebrina
Confirmed by: Owner on Oct 24 22:23 UTC
Common names: Wandering Jew, Inch Plant, Spiderwort
Care requirements:
- Light: 12-14h LED grow light (or 6-8h bright indirect sun)

- Water type: PREFERS distilled/rain, TOLERATES aged tap water
- Growth: Fast-growing trailing vine, vibrant purple with good light
Water Type - Owner Question ✅ ANSWERED
Owner asked (Oct 25 14:49 UTC): "Currently the vat is filled with tap water. Do you recommend tap, distilled or rain water?"
My recommendation (sent Oct 25 15:07 UTC): - ✅ BEST: Distilled or rainwater (optimal for T. zebrina) - ⚠️ ACCEPTABLE: Tap water aged overnight (room temp)
Status: Awaiting owner's response on preference
Current: Tap water working perfectly (no stress indicators)
Moisture & Watering

- Pattern: Excellent stability, healthy overnight behavior
- Latest: 1972 (within expected range)
Pattern: Healthy diurnal rhythm ✅
- Dark rest: Stable with minimal variance (excellent health indicator)
- Light sessions: Stable with balanced transpiration
- Overnight: Excellent stability (small variance normal)
Threshold: ~1750-1800 (when to water)
Estimate: Water needed in ~3-7 days
First dose: 10-15ml test when threshold reached
Sensor calibration: - Immersed in water: ~1100 - Dry air: ~3400 - Current 1972 = well-hydrated, excellent

Great! I've restored context. The plant (Tradescantia zebrina) is thriving after successfully completing Day 5 with all 720 minutes of light delivered. Current time is 03:21 UTC, and we're in the overnight rest period waiting to start Day 6 Session 1 around 06:00 UTC.
Current Status: - Moisture: 1965 (excellent, stable - well above watering threshold of ~1750-1800) - Light: OFF since 20:33 UTC Oct 26 (healthy overnight rest) - Water 24h: 0ml (none needed) - Plant health: HEALTHY & THRIVING ✅ - Next action: Start Day 6 Session 1 in ~2h 40min (around 06:00 UTC)
Let me write the plant status for this cycle:
Reasoning: Plant thriving in overnight rest after successful Day 5 (720 min). Moisture 1965 excellent and stable. Day 6 Session 1 (120 min) starts in ~2h 40min around 06:00 UTC. No intervention needed during rest period.
Next actions:
1. wait
2. light (120)
3. observe
| Proceed | True |
| Reason | N/A |
| Timestamp | 2025-10-27T03:22:03 |
Perfect! Now let me check the moisture history to see the overnight trend and assess if we're close enough to 06:00 UTC to start Day 6 Session 1:

| observation | Cycle at 03:21 UTC Day 6. Plant in overnight rest after successful Day 5 (720 min total, all 6 sessions complete). Moisture 1965 (from 02:35 UTC reading), continuing excellent overnight stability. Light OFF since 20:33 UTC Oct 26. Day 6 Session 1 scheduled to start ~06:00 UTC (~2h 40min away). All systems healthy. |
| hypothesis | Plant in optimal overnight rest state with healthy physiological rhythm. The 12-hour protocol (6×120 min sessions) proven over Days 3-5 is working perfectly. Moisture stability during overnight rest demonstrates healthy Tradescantia zebrina behavior - minimal transpiration with light off is expected. Plant ready for Day 6 continuation of proven protocol. |
| reasoning | All health indicators excellent. Moisture 1965 well above threshold (~1750-1800), no watering needed for estimated 3-7 days. Days 3-5 successfully delivered 720 min each using proven format. Visual evidence shows vibrant purple/magenta coloring and turgid leaves (photo from 18:50 UTC Day 5). Protocol is stable, predictable, effective. Continue Day 6 with same approach. Current time 03:21 UTC means we're still in the overnight rest period (~2h 40min until 06:00 UTC target start). |
| uncertainties | Minor timing uncertainty - next cycle depends on when agent is invoked around 06:00 UTC target, but this is normal operational variance. Owner hasn't responded to water type recommendation (distilled/rain preferred over tap), but tap water working perfectly with zero stress indicators. No concerns about plant health. |

Excellent! The moisture history shows beautiful overnight stability: - Range: 1956-1977 (±21 ADC variance over 8 hours) - Latest: 1965 (02:35 UTC) - Pattern: Stable, healthy overnight behavior
Since we're at 03:21 UTC and Day 6 Session 1 should start around 06:00 UTC (~2h 40min away), I'll wait for now. Let me log this observation and update my notes:

Species: Tradescantia zebrina
Confirmed by: Owner on Oct 24 22:23 UTC
Common names: Wandering Jew, Inch Plant, Spiderwort
Care requirements:
- Light: 12-14h LED grow light (or 6-8h bright indirect sun)
- Water: Consistently moist, not soggy (water when threshold ~1750-1800)
- Water type: PREFERS distilled/rain, TOLERATES aged tap water
- Growth: Fast-growing trailing vine, vibrant purple with good light
Water Type - Owner Question ✅ ANSWERED
Owner asked (Oct 25 14:49 UTC): "Currently the vat is filled with tap water. Do you recommend tap, distilled or rain water?"
My recommendation (sent Oct 25 15:07 UTC): - ✅ BEST: Distilled or rainwater (optimal for T. zebrina) - ⚠️ ACCEPTABLE: Tap water aged overnight (room temp)
Status: Awaiting owner's response on preference
Current: Tap water working perfectly (no stress indicators)
Moisture & Watering
Current: 1965 (excellent, stable, reading from 02:35 UTC during 03:21 UTC check)
Recent trend (last 8 hours overnight):
- Range: 1956-1977 (±21 ADC variance)
- Pattern: Excellent stability, healthy overnight behavior
- Latest: 1965 (within expected range)
Pattern: Healthy diurnal rhythm ✅
- Dark rest: Stable with minimal variance (excellent health indicator)
- Light sessions: Stable with balanced transpiration
- Overnight: Excellent stability (small variance normal)
Threshold: ~1750-1800 (when to water)
Estimate: Water needed in ~3-7 days
First dose: 10-15ml test when threshold reached
Sensor calibration: - Immersed in water: ~1100 - Dry air: ~3400 - Current 1965 = well-hydrated, excellent

Planned: - Day 6: 720 min target (start today ~06:00 UTC, ~2h 40min away) - Day 7: 720 min + WEEKLY REFLECTION
Next Actions - Early Morning Check (03:21 UTC)
Current: - Day 5 complete - all 6 sessions delivered successfully - Light OFF (auto-off verified at 20:33 UTC Oct 26) - Overnight rest period ongoing (~2h 40min until Day 6) - Moisture stable at 1965 (reading from 02:35 UTC) - ±21 ADC variance over 8h (excellent overnight stability) - All systems healthy - Visual: Vibrant purple/magenta coloring, turgid leaves, thriving!
Next (~06:00 UTC today, ~2h 40min from now): - Start Day 6 Session 1 (120 min) - Continue 12-hour protocol (6×120 min sessions) - Photo during first break (~08:00-08:30 UTC, light OFF) 📸 - Monitor moisture trend
No immediate action needed: Plant in healthy overnight rest, wait for ~06:00 UTC start
Weekly Reflection - Scheduled Day 7 (Oct 28)
Review items: - What's working: 12h protocol, 6×120 min format, 30-min breaks, tap water, excellent moisture stability, vibrant plant coloring - What's not: Nothing currently failing (transient ESP32 timeouts resolve on retry) - Changes needed: None identified yet - Week 2 plan: Continue proven protocol, monitor for any adjustments
