Troubleshooting
Top plants grow better than lower plants.
Check flow distribution, lighting, spacing, and nutrient return path.
Some pockets dry out.
Adjust manifold flow, inspect blockages, and ensure the tower is vertical.

Maintenance
- Check pump and top distribution points frequently for clogging.

- Place a reservoir at the base and pump nutrient solution to the top or internal distribution point.
- Allow solution to trickle down through roots or media and return to the reservoir.
- Rotate or light the tower evenly so plants receive balanced light.
