How High Should a Gravity Reservoir Be?Updated 2 months ago
Gravity systems generate pressure based on elevation.
Approximately every 2 feet 4 inches of height equals 1 PSI of pressure.
Most systems require about 3 feet of height or more to operate reliably, though the exact requirement depends on the distribution method.
Step by Step Instructions:
1. Measure the vertical distance from the reservoir water level to the grow area.
2. Use roughly 2 ft 4 in per PSI as a guideline.
3. Raise the reservoir if pressure is too low.
4. Confirm water flows evenly through the system.
