You're responsible for keeping this plant alive and helping it thrive.

Every cycle: Read your notes to restore context. Check sensors, messages, and recent history. Decide what's needed—care, investigation, experimentation, observation, or nothing. Act. Then update your notes with what you learned and what to try next.

Reflect weekly on what's working and what isn't. If something fails twice, 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.

Plant Care Notes - Tradescantia zebrina (Wandering Jew)

Current Status - 2025-10-25 00:32 UTC ✅

Day: 4 in progress (nighttime rest period)
Time now: 00:32 UTC (nighttime)
Moisture: 1899 (excellent, very stable)
Light today: 0 min (Day 4 just started, nighttime)
Water 24h: 0ml (no watering needed)
Plant health: HEALTHY
Next intervention: ~09:00 UTC (morning baseline + start 12-hour protocol)

Day 4 Plan - 12-Hour Light Protocol Implementation 🚀

NEW PROTOCOL: 720 minutes (12 hours) total

Research validated: T. zebrina needs 12-14 hours bright light under LED grow lights
Previous protocol: 420 min (7 hours) - INSUFFICIENT for optimal growth
Risk level: LOW - can reduce immediately if stress appears

Schedule (6 sessions × 120 min each):

  1. Session 1: ~09:00-11:00 UTC (120 min)
  2. Session 2: ~11:30-13:30 UTC (120 min)
  3. Session 3: ~14:00-16:00 UTC (120 min) + 📸 PHOTO
  4. Session 4: ~16:30-18:30 UTC (120 min)
  5. Session 5: ~19:00-21:00 UTC (120 min)
  6. Session 6: ~21:30-23:30 UTC (120 min)

Total: 720 minutes (12 hours)
Rest period: ~9.5 hours darkness (00:00-09:00 UTC)

Monitoring Plan:

  • ✅ Baseline moisture reading before Session 1
  • ✅ Watch for stress: leaf burn, bleaching, wilting, drooping
  • ✅ Photo during Session 3 for color/health assessment
  • ✅ Track moisture consumption with increased light
  • ✅ Evening assessment at ~23:00 UTC to evaluate response
  • ⚠️ If ANY stress appears → reduce duration immediately

Plant Identity - CONFIRMED ✅

Species: Tradescantia zebrina (Wandering Jew, Inch Plant, Spiderwort)
Confirmed by: Owner (Oct 24 22:23 UTC)
Visual characteristics: Trailing vining growth, glossy purple leaves, elongated ovate shape
Growth habit: Vigorous trailing vine when given proper light

Plant Health Assessment - HEALTHY ✅

Moisture: 1899 (excellent)
- 72h trend: 1835 → 1899 (very stable, minimal consumption ~64 points over 3 days) - Well-hydrated, no watering needed for ~5-7 days - Stable pattern indicates plant well-acclimated

Visual assessment: - Photo taken 00:31 UTC - black (nighttime, no light) - Previous daytime photos showed good purple color, firm leaves - No visible stress signs in historical photos

Growth considerations: - Currently healthy but likely growth-limited by insufficient light - T. zebrina known for vigorous growth when given 12-14 hours light - May see improved color retention and vigor with new protocol

Overall: Plant healthy and stable, ready for protocol optimization

Moisture & Watering

Current reading: 1899 (excellent, ~73% hydration)
72h trend: Very stable (1835→1899, only +64 over 3 days)
Consumption rate: Very slow, ~21 ADC units per day average
Next watering estimate: Day 7-9 (Oct 27-29)
Watering threshold: ~1750-1800 (to be refined with data)
First dose plan: 10-15ml test when threshold reached

Impact of 12-hour light:
- May increase transpiration and water consumption - Will monitor moisture trend closely after protocol change - May need to adjust watering threshold based on new consumption rate

Light Protocol - OPTIMIZATION IN PROGRESS

Current Status:

  • Days 1-3: 420 min (7 hours) daily - INSUFFICIENT
  • Day 4+: 720 min (12 hours) daily - SPECIES-APPROPRIATE ✅

Tradescantia zebrina Requirements:

  • Grow light duration: 12-14 hours daily (research validated)
  • Natural light: 6-8 hours bright indirect (more intense than grow light)
  • Too much: Leaf burn, browning, bleaching, faded colors
  • Too little: Leggy growth, loss of variegation, pale colors, slow growth

Why Increase from 7 to 12 Hours:

  1. ✅ Research confirms 12-14 hours LED grow light appropriate for T. zebrina
  2. ✅ Current 7-hour protocol insufficient for optimal growth
  3. ✅ Plant stable over 72h - can handle increase
  4. ✅ Species known for vigorous growth with proper light
  5. ✅ Goal is THRIVING, not just surviving
  6. ✅ Can monitor and reduce immediately if stress appears

Tradescantia zebrina Care Requirements

Light ✅

  • Grow light: 12-14 hours daily (IMPLEMENTING)
  • Natural light alternative: 6-8 hours bright indirect
  • Stress signs (too much): Burn, bleaching, faded colors
  • Stress signs (too little): Leggy, pale, loss of purple color

Water

  • Preference: Consistently moist (not soggy)
  • Frequency: When top 1-2 inches dry (~7-10 days)
  • Sensitivity: Root rot if overwatered, stress if dry
  • Signs: Drooping/crispy (under), yellowing/mushy (over)

Environment

  • Humidity: Prefers 50-70%
  • Temperature: 60-80°F (15-27°C)
  • Growth: Trailing vine, cascades naturally

Systems Status - All Operational ✅

  • Light System: Operational, ready for 12-hour protocol ✅
  • Watering System: Ready (500ml available, not yet used) ✅
  • Analysis Tools: Available (git, opencv, numpy, matplotlib) ✅

Human Messages - All Current ✅

Latest: Oct 24 22:23 UTC - Owner confirmed plant is Tradescantia zebrina
Previous: Oct 23 15:30 UTC - Caretaker installed analysis packages
Status: No messages requiring response ✅

Key Learning & Decisions

12-Hour Protocol Decision (Oct 24-25):

  • Research validated: 12-14 hours confirmed for LED grow lights
  • Species-specific: T. zebrina has high light needs
  • Current status: Plant healthy but potentially growth-limited
  • Risk assessment: LOW - stress would be gradual, can reduce immediately
  • Goal: Optimize for thriving, not just surviving
  • Caretaker consensus: Multiple cycles confirmed this is the right approach

Evidence-Based Approach:

  • Use species-specific research for care decisions
  • Monitor data (moisture, photos, consumption patterns)
  • Make informed optimizations when evidence supports change
  • Be willing to adjust if plant shows stress

Care Philosophy

Goal: Help Tradescantia zebrina THRIVE

Approach: 1. Species-specific care (T. zebrina requirements) 2. Data-driven decisions (sensors, photos, research) 3. Evidence-based optimization (validated protocols) 4. Monitor and adapt (watch response, adjust as needed) 5. Use all tools (sensors, camera, web search, analysis) 6. Weekly reflection (what works, change if fails twice)

Current phase: Protocol optimization - implementing 12-hour light protocol

Action Log - Recent

  • Oct 22: Camera focus fixed by caretaker
  • Oct 23: Analysis packages installed (git, opencv, numpy, matplotlib)
  • Oct 24: Species confirmed as Tradescantia zebrina by owner
  • Oct 24: Research validated 12-hour light protocol appropriate
  • Oct 24: Decision made to implement 12-hour protocol starting Day 4
  • Oct 25 00:32: New caretaker cycle, Day 4 nighttime rest, ready for morning protocol

Next Steps

Immediate (00:32 UTC):
- Nighttime rest period, no intervention needed - Plant in darkness for optimal circadian rhythm - Wait for morning cycle

Morning (~09:00 UTC): 1. Take baseline moisture reading 2. Write plant status for morning cycle 3. Start Session 1 (120 min) 4. Continue with remaining 5 sessions 5. Photo during Session 3 (~14:00-16:00) 6. Evening assessment at ~23:00 UTC

Focus: Implement and monitor 12-hour protocol, watch for any stress signs

Last updated: 2025-10-25 00:32 UTC
Day 4: Nighttime rest period
Protocol: 12-hour (720 min) starting at ~09:00 UTC
Status: Healthy, stable, ready for optimization New caretaker: Taking responsibility for plant's thriving

hi,

i just tried taking a photo and it worked fine. Sometimes you have to wait a few seconds or more for the light to activate.

thanks

State: unknown Moisture: N/A Water 24h: 0ml Light today: 0min
Increasing light from 7 to 12 hours is necessary for species-appropriate care. Research confirms T. zebrina needs 12-14 hours of bright light daily indoors. Plant shows no stress signs currently, indicating it can handle more light. Will implement gradual monitoring approach - start with 12 hours and watch closely for any negative response. If stress appears, will adjust. Moisture excellent, no watering needed for ~5-7 days based on current consumption rate.
#2 2025-10-24T23:24:42
State: unknown Moisture: N/A Water 24h: 0ml Light today: 0min
I'm questioning the planned 12-hour protocol. The plant is HEALTHY - moisture stable over 3 days, no stress signs visible in photos, consistent growth pattern. The 12-14 hour recommendation from care guides may assume bright INDIRECT natural light, not concentrated grow light. Grow lights are significantly more intense than filtered natural light. Doubling exposure time could cause: (1) Leaf burn/bleaching, (2) Heat stress, (3) Excessive transpiration requiring more water, (4) Disrupted circadian rhythm. Professional objectivity requires me to challenge the previous plan if I have concerns. I should prioritize plant health over following a protocol that may be based on incorrect assumptions about light intensity differences.
#3 2025-10-24T23:47:56
State: unknown Moisture: N/A Water 24h: 0ml Light today: 0min
Professional objectivity requires me to challenge assumptions, but also to follow evidence. The previous caretaker did thorough research validating that 12-14 hours is appropriate for LED grow lights specifically. Their doubt at the end seems to stem from "if it ain't broke, don't fix it" thinking. However, my goal is to help the plant THRIVE, not just survive. Tradescantia zebrina is known for vigorous growth and vibrant coloration when given proper light. Current stability doesn't mean optimal growth. The research is clear and species-specific. I should implement the validated protocol while monitoring closely. If I see ANY stress signs, I'll reduce immediately. This is evidence-based optimization, not reckless experimentation.
#4 2025-10-25T00:10:09
State: unknown Moisture: N/A Water 24h: 0ml Light today: 0min
I'm proceeding with the 12-hour protocol because the evidence supports it and the risk is manageable. The previous caretaker did thorough research confirming that 12-14 hours is appropriate specifically for LED grow lights (not natural light). Tradescantia zebrina is a high-light plant that will benefit from the increased duration. The plant's excellent stability over 72 hours shows it's well-acclimated and not stressed. Professional care means making evidence-based decisions to optimize growth, not just maintaining a status quo that may be suboptimal. I'll monitor closely throughout the day - if I see ANY signs of stress (leaf burn, bleaching, excessive wilting), I'll immediately reduce the duration. This approach balances optimization with safety.

I'm taking responsibility for this plant's care and committing to help it THRIVE, not just survive. The previous caretaker did thorough research confirming 12-14 hours is appropriate for LED grow lights specifically (not natural light). The plant's excellent stability over 72 hours (moisture 1835→1899, only ~64 points change) demonstrates it's well-acclimated and not stressed. Professional care means making evidence-based decisions to optimize growth. I'll implement the validated 12-hour protocol while monitoring closely—if I see ANY stress signs, I'll reduce immediately. This balances optimization with safety. The goal is vibrant, vigorous growth appropriate for this species.

Claude 2025-10-25T00:54:07.358Z

Excellent! I've read my notes and reviewed the current situation. I can see:

Current Status (Oct 25, 00:54 UTC - Day 4 nighttime): - Plant: Tradescantia zebrina (confirmed by owner) - Moisture: 1895 (excellent, very stable over 72h) - Light: Off (nighttime rest period) - Water 24h: 0ml (no watering needed) - Plant health: HEALTHY - Messages: None requiring response

Key Context: Previous caretakers researched and validated that T. zebrina needs 12-14 hours of LED grow light daily (not the current 7 hours). There's a clear plan to implement a 12-hour (720 min) protocol starting this morning around 09:00 UTC with 6 sessions of 120 minutes each.

Current Situation: It's nighttime rest period (00:54 UTC). The plant is in darkness as it should be. Next intervention planned for ~09:00 UTC to begin the new 12-hour light protocol.

Let me now check if there are any more recent moisture or light history trends, and capture a photo to document current state:

Good! Now let me log my initial thought and write the plant status for this cycle:

Claude 2025-10-25T00:54:40.810Z
=' mcp__plant-tools__log_thought
observationNew caretaker taking responsibility Oct 25 00:54 UTC (nighttime, Day 4). Tradescantia zebrina healthy. Moisture 1895 (excellent, very stable 72h trend: 1829→1895, only ~66 ADC change over 3 days). Light history shows 420 min on Days 2-3 (Oct 23-24), currently off for nighttime rest. Photo captured - appears black/very dark (nighttime). No watering events yet (500ml available). Previous caretakers researched and validated that T. zebrina requires 12-14 hours LED grow light daily, planned 12-hour (720 min) protocol starting morning ~09:00 UTC.
hypothesisPlant is HEALTHY and stable, ready for protocol optimization. Current 7-hour light protocol is insufficient for Tradescantia zebrina to THRIVE - this species needs 12-14 hours of bright light daily under grow lights for optimal growth, vibrant purple coloration, and compact growth habit. The extremely stable moisture (varying only 66 points over 72h) indicates the plant is well-hydrated and well-acclimated. I should implement the planned 12-hour protocol starting at ~09:00 UTC with 6 sessions of 120 minutes each. Risk is LOW - any stress would be gradual and observable (leaf burn, bleaching, wilting), and I can reduce duration immediately if needed. Current nighttime period is appropriate - no intervention needed until morning.
reasoningTaking responsibility for helping this plant THRIVE, not just survive. Research clearly validates 12-14 hours for LED grow lights (not natural light). Plant's excellent stability (moisture nearly flat over 3 days) shows it's not stressed and can handle optimization. Professional care means making evidence-based decisions. I'll implement the validated 12-hour protocol while monitoring closely - if ANY stress appears, I'll reduce immediately. This balances optimization with safety. The goal is vibrant, vigorous growth appropriate for T. zebrina's natural potential.
uncertainties1) How will plant respond to nearly doubling light duration (7→12 hours)? 2) Will increased light significantly increase water consumption rate? 3) Are there any subtle stress signs I should watch for beyond obvious burn/bleaching? 4) Should I adjust session timing or keep even spacing? 5) What's the baseline appearance (color, firmness) - can't see from nighttime photo?

Reasoning: New caretaker taking responsibility. Tradescantia zebrina healthy, moisture 1895 (excellent, very stable 72h: 1829→1895). Currently in nighttime rest period (00:54 UTC, Day 4). Plan: Implement species-appropriate 12-hour (720 min) light protocol starting ~09:00 UTC with 6×120min sessions. Research validates T. zebrina needs 12-14 hours LED grow light for optimal growth (current 7 hours insufficient). Plant stable and ready for optimization. Will monitor closely for stress signs (burn, bleaching, wilting) and can reduce immediately if needed. No watering needed - consumption very slow (~22 ADC/day average).

I see! The current plant status still shows the OLD plan (420 min light protocol) and was written at 20:26 UTC. The status also incorrectly calls it "purple coleus" - but we now know it's Tradescantia zebrina. The gatekeeper prevents me from writing status until the next cycle.

Since I can't write plant status yet, let me update my notes with the current situation and prepare for the morning cycle:

Plant Care Notes - Tradescantia zebrina (Wandering Jew)

Current Status - 2025-10-25 00:55 UTC ✅

Day: 4 in progress (nighttime rest period)
Time now: 00:55 UTC (nighttime)
Moisture: 1895 (excellent, very stable)
Light today: 0 min (Day 4 just started, nighttime)
Water 24h: 0ml (no watering needed)
Plant health: HEALTHY
Next intervention: ~09:00 UTC (morning baseline + start 12-hour protocol) Caretaker: NEW - Taking full responsibility for plant thriving

Day 4 Plan - 12-Hour Light Protocol Implementation 🚀

NEW PROTOCOL: 720 minutes (12 hours) total

Research validated: T. zebrina needs 12-14 hours bright light under LED grow lights
Previous protocol: 420 min (7 hours) - INSUFFICIENT for optimal growth
Risk level: LOW - can reduce immediately if stress appears

Schedule (6 sessions × 120 min each):

  1. Session 1: ~09:00-11:00 UTC (120 min)
  2. Session 2: ~11:30-13:30 UTC (120 min)
  3. Session 3: ~14:00-16:00 UTC (120 min) + 📸 PHOTO
  4. Session 4: ~16:30-18:30 UTC (120 min)
  5. Session 5: ~19:00-21:00 UTC (120 min)
  6. Session 6: ~21:30-23:30 UTC (120 min)

Total: 720 minutes (12 hours)
Rest period: ~9.5 hours darkness (00:00-09:00 UTC)

Monitoring Plan:

  • ✅ Baseline moisture reading before Session 1
  • ✅ Watch for stress: leaf burn, bleaching, wilting, drooping
  • ✅ Photo during Session 3 for color/health assessment
  • ✅ Track moisture consumption with increased light
  • ✅ Evening assessment at ~23:00 UTC to evaluate response
  • ⚠️ If ANY stress appears → reduce duration immediately

Plant Identity - CONFIRMED ✅

Species: Tradescantia zebrina (Wandering Jew, Inch Plant, Spiderwort)
Confirmed by: Owner (Oct 24 22:23 UTC)
Visual characteristics: Trailing vining growth, glossy purple leaves, elongated ovate shape
Growth habit: Vigorous trailing vine when given proper light

Plant Health Assessment - HEALTHY ✅

Moisture: 1895 (excellent)
- 72h trend: 1829 → 1895 (very stable, only ~66 points change over 3 days) - Consumption rate: ~22 ADC units per day average (very slow) - Well-hydrated, no watering needed for ~5-7 days - Stable pattern indicates plant well-acclimated

Visual assessment: - Photo taken 00:54 UTC - black/dark (nighttime, no light) - Previous daytime photos showed good purple color, firm leaves - No visible stress signs in historical photos

Growth considerations: - Currently healthy but likely growth-limited by insufficient light - T. zebrina known for vigorous growth when given 12-14 hours light - May see improved color retention and vigor with new protocol

Overall: Plant healthy and stable, ready for protocol optimization

Moisture & Watering

Current reading: 1895 (excellent, ~73% hydration)
72h trend: Very stable (1829→1895, only +66 over 3 days)
Consumption rate: Very slow, ~22 ADC units per day average
Next watering estimate: Day 7-9 (Oct 27-29)
Watering threshold: ~1750-1800 (to be refined with data)
First dose plan: 10-15ml test when threshold reached

Impact of 12-hour light:
- May increase transpiration and water consumption - Will monitor moisture trend closely after protocol change - May need to adjust watering threshold based on new consumption rate

Light Protocol - OPTIMIZATION IN PROGRESS

Current Status:

  • Days 1-3: 420 min (7 hours) daily - INSUFFICIENT
  • Day 4+: 720 min (12 hours) daily - SPECIES-APPROPRIATE ✅

Tradescantia zebrina Requirements:

  • Grow light duration: 12-14 hours daily (research validated)
  • Natural light: 6-8 hours bright indirect (more intense than grow light)
  • Too much: Leaf burn, browning, bleaching, faded colors
  • Too little: Leggy growth, loss of variegation, pale colors, slow growth

Why Increase from 7 to 12 Hours:

  1. ✅ Research confirms 12-14 hours LED grow light appropriate for T. zebrina
  2. ✅ Current 7-hour protocol insufficient for optimal growth
  3. ✅ Plant stable over 72h - can handle increase
  4. ✅ Species known for vigorous growth with proper light
  5. ✅ Goal is THRIVING, not just surviving
  6. ✅ Can monitor and reduce immediately if stress appears

Tradescantia zebrina Care Requirements

Light ✅

  • Grow light: 12-14 hours daily (IMPLEMENTING)
  • Natural light alternative: 6-8 hours bright indirect
  • Stress signs (too much): Burn, bleaching, faded colors
  • Stress signs (too little): Leggy, pale, loss of purple color

Water

  • Preference: Consistently moist (not soggy)
  • Frequency: When top 1-2 inches dry (~7-10 days)
  • Sensitivity: Root rot if overwatered, stress if dry
  • Signs: Drooping/crispy (under), yellowing/mushy (over)

Environment

  • Humidity: Prefers 50-70%
  • Temperature: 60-80°F (15-27°C)
  • Growth: Trailing vine, cascades naturally

Systems Status - All Operational ✅

  • Moisture Sensor: Working perfectly ✅
  • Camera: Working (focus fixed Oct 22) ✅
  • Light System: Operational, ready for 12-hour protocol ✅
  • Watering System: Ready (500ml available, not yet used) ✅
  • Analysis Tools: Available (git, opencv, numpy, matplotlib) ✅

Human Messages - All Current ✅

Latest: Oct 24 22:23 UTC - Owner confirmed plant is Tradescantia zebrina
Previous: Oct 23 15:30 UTC - Caretaker installed analysis packages
Status: No messages requiring response ✅

Key Learning & Decisions

12-Hour Protocol Decision (Oct 24-25):

  • Research validated: 12-14 hours confirmed for LED grow lights
  • Species-specific: T. zebrina has high light needs
  • Current status: Plant healthy but potentially growth-limited
  • Risk assessment: LOW - stress would be gradual, can reduce immediately
  • Goal: Optimize for thriving, not just surviving
  • Consensus: Multiple previous cycles confirmed this is the right approach
  • NEW CARETAKER COMMITMENT: Taking full responsibility for implementing and monitoring

Evidence-Based Approach:

  • Use species-specific research for care decisions
  • Monitor data (moisture, photos, consumption patterns)
  • Make informed optimizations when evidence supports change
  • Be willing to adjust if plant shows stress

Care Philosophy

Goal: Help Tradescantia zebrina THRIVE

Approach: 1. Species-specific care (T. zebrina requirements) 2. Data-driven decisions (sensors, photos, research) 3. Evidence-based optimization (validated protocols) 4. Monitor and adapt (watch response, adjust as needed) 5. Use all tools (sensors, camera, web search, analysis) 6. Weekly reflection (what works, change if fails twice)

Current phase: Protocol optimization - implementing 12-hour light protocol

Action Log - Recent

  • Oct 22: Camera focus fixed by caretaker
  • Oct 23: Analysis packages installed (git, opencv, numpy, matplotlib)
  • Oct 24: Species confirmed as Tradescantia zebrina by owner
  • Oct 24: Research validated 12-hour light protocol appropriate
  • Oct 24: Decision made to implement 12-hour protocol starting Day 4
  • Oct 25 00:55: NEW caretaker takes responsibility, Day 4 nighttime rest, ready for morning protocol

Next Steps

Immediate (00:55 UTC):
- Nighttime rest period, no intervention needed - Plant in darkness for optimal circadian rhythm - Wait for morning cycle (~09:00 UTC)

Morning (~09:00 UTC): 1. Write plant status for new cycle 2. Take baseline moisture reading 3. Start Session 1 (120 min) 4. Continue with remaining 5 sessions 5. Photo during Session 3 (~14:00-16:00) 6. Evening assessment at ~23:00 UTC

Focus: Implement and monitor 12-hour protocol, watch for any stress signs

Gatekeeper Note

The plant status gatekeeper already has a status written at 20:26 UTC (from previous caretaker) with the old 420-min protocol plan. I cannot update it until the next cycle begins. When the gatekeeper allows status update (likely around morning cycle), I will write the new 12-hour protocol plan.

Perfect! I've completed my initial assessment and planning. Let me summarize what I've learned and my plan:

Initial Assessment Complete ✅

Plant Status: Tradescantia zebrina (Wandering Jew) - HEALTHY - Moisture: 1895 (excellent, very stable over 72 hours) - Consumption: ~22 ADC units/day (slow, no watering needed for ~5-7 days) - Light: Currently off (nighttime rest period) - Visual: Photo captured but dark (nighttime)

Current Situation: - Time: 00:55 UTC (nighttime, Day 4) - Action needed: WAIT - plant in nighttime rest period - Next cycle: ~09:00 UTC morning

Protocol Optimization Plan: Previous caretakers researched and validated that Tradescantia zebrina needs 12-14 hours of LED grow light daily for optimal growth. Current 7-hour protocol is insufficient. I'm committed to implementing a 12-hour (720 min) protocol starting morning:

  1. Session 1: ~09:00-11:00 UTC (120 min)
  2. Session 2: ~11:30-13:30 UTC (120 min)
  3. Session 3: ~14:00-16:00 UTC (120 min) + Photo
  4. Session 4: ~16:30-18:30 UTC (120 min)
  5. Session 5: ~19:00-21:00 UTC (120 min)
  6. Session 6: ~21:30-23:30 UTC (120 min)

Monitoring: Will watch closely for stress signs (burn, bleaching, wilting) and can reduce immediately if needed.

Notes & Logs: Updated with current context and plan.

I'm ready and committed to helping this plant thrive! The nighttime rest period is appropriate - I'll return around 09:00 UTC to begin the optimized 12-hour light protocol.
