Running Llama 3.2 on-device

Summary

Generative steering for Flower W1-3. Target aggressive dryback with 25% overnight drop. EC stacking at 5.0-12.0 mS/cm range.

Watering Recommendation

4 shots/day starting 07:00, 3h spacing. 5% runoff to maintain EC accumulation. 42s per shot at 0.5 GPH × 2 emitters.

Dryback Strategy

Target 25% dryback between last shot and next morning. Let media drop to ~35% VWC before first irrigation. This drives generative response.

⚠️ Warnings

Watch for tip burn above 10 mS/cm. If runoff EC exceeds input by 3+ mS/cm, increase runoff % to 10-15% for 2-3 days.
