📈 Yield trend: 2.98 > 3.15 > 3.27 lb/light (trending up over 3 runs)
🎯 Primary lever: VPD management and irrigation timing
Tightening VPD into the 1.2-1.4 kPa range during peak flower and adjusting feed EC based on runoff data should unlock the next step up.
🔁 What Worked — Repeat This
Gradual PPFD ramp from 600 to 950 over weeks 1-3
No light stress observed at any point, unlike prior run where starting at 800 caused leaf tucking in week 1. Gradual ramp let plants acclimate without defensive response.
Confidence: High
Consistent 20-25% overnight drybacks in rockwool
Strong generative response without the wilting seen when drybacks exceeded 30% on Run 6. This cultivar prefers moderate steering in 3-gal rockwool.
Confidence: High
Single top at day 14 of veg for 6-cola structure
Even canopy with minimal staking needed. 12% trim ratio suggests light penetration was adequate across the canopy without supplemental under-canopy lighting.
Confidence: Medium

✅ What Went Well
- Improved to 3.27 lb/light from 3.15 on prior Wedding Cake run
- Tight 12% trim ratio with minimal lower canopy intervention needed
⚠️ What Didn't Go Well
- VPD consistently below target during mid-flower (0.9-1.0 vs 1.2-1.4 kPa)
- EC runoff drift from 3.2 to 4.1 without feed adjustment suggests irrigation timing needs tightening
🔍 Key Contributors
- Gradual PPFD ramp (600 to 950 over first 3 weeks) avoided early light stress
- Consistent overnight drybacks (20-25%) drove strong generative response without oversteering
💡 Suggestions for Next Run
1. Push VPD to 1.2-1.4 kPa during weeks 4-7

2. Tighten irrigation scheduling based on runoff EC

🔬 Phase Analysis
🌿 Clone Phase
Standard 10-day clone phase in propagation room
✅ What went well
- All 72 clones rooted within 10 days, zero losses
⚠️ What didn't go well
- No clone-specific environmental data captured for AI analysis
💡 Insights
- Consider logging clone room humidity and dome VPD to correlate with rooting speed
🌿 Veg Phase
28-day veg produced 18-inch plants at flip, healthy canopy
✅ What went well
- Plants reached 18-inch target height with good branch structure
- Topped once at day 14, 6 main colas per plant achieved
⚠️ What didn't go well
- Limited veg sensor data (only last 3 days captured)
💡 Insights
- 28-day veg with 3-gal rockwool appropriate for target density of 3 plants per light
🌿 Flower Phase
58-day flower with strong late-cycle push, minor humidity challenges in week 7
✅ What went well
- Achieved 3.27 lb/light, up from 3.15 last run of same cultivar
- Consistent 20-25% overnight drybacks maintained through flower
- Canopy stayed relatively even with minimal lollipop labor needed
⚠️ What didn't go well
- Humidity spiked to 68% RH for 3 days in week 7 during HVAC service
- VPD ran low (0.9-1.0 kPa) during weeks 5-6 vs target 1.2-1.4
- EC crept from 3.2 to 4.1 in runoff weeks 4-6 without adjustment
💡 Insights
- This cultivar responds well to 900-1000 PPFD range with gradual ramp from flip
- 3-gal rockwool needed 6-8 irrigations daily by mid-flower at current EC
- Week 7 humidity spike correlates with reduced resin production in lower canopy
🌿 Dry Phase
11-day dry achieved target 0.59 water activity with steady VPD control
✅ What went well
- Final water activity 0.58-0.61 across all positions, solidly in optimal range
- 11-day dry with no hot spots or uneven drying detected
⚠️ What didn't go well
- Slight over-dry on top rack (0.57 aw) vs bottom rack (0.61 aw)
💡 Insights
- Wedding Cake dried slightly slower than expected, likely due to dense bud structure
- Consistent 60°F/60% RH approach worked well for this cultivar
🌿 Bucking Phase
Clean 1-day buck and trim at proper moisture
✅ What went well
- Clean separation, minimal trichome loss during processing
- 12% trim ratio indicates strong bud-to-leaf development
⚠️ What didn't go well
- No issues reported during processing
💡 Insights
- Bucking at 0.59 aw was the sweet spot for this cultivar's bud density
📝 Notes:
Solid flower phase data with daily sensor readings for 58 days. Irrigation and runoff tracking provides clear nutrient management picture. Water activity testing at multiple dry room positions.
