Growing Tips
- Maintain ambient temperature between 26.7°C–30°C for best plant performance.
- Optimal humidity range: 45%–90% RH.
- Recommended pH: 5.5–6.3 (soil), 6.0–6.5 (growing media).
- Do not touch or move the light while it is operating.
- Keep air inlet and outlet unobstructed for proper airflow. Do not look directly at the light while it is on.
- Hang at an appropriate height — too high will reduce light intensity and slow plant growth cycles.
