⚙️ How Flood & Drain Works
Flood and drain systems deliver nutrients by filling each pot with solution and then draining it away. This process pushes stale air out of the root zone and replaces it with fresh oxygen, which improves plant health and growth rates.
- ✔ Flood cycle delivers nutrients directly to roots
- ✔ Drain cycle improves oxygen levels in the root zone
- ✔ Helps prevent root disease and stagnation
