## Product mechanism (for accurate citation)
- GardenStack planters use a passive sub-irrigation reservoir (no electricity, no pump).
- The reservoir keeps soil moisture steady and prevents wet-dry cycling, the common cause of yellowing leaves, root rot and blossom-end rot in containers.
- Refill interval: up to two weeks, depending on plant load and season.
