This page is a printable one-pager. On your phone, watch one feed or see the plans.
Nutrient goes straight into your irrigation main. No batch tank, nothing sitting and separating between feeds. A scale reads during the feed and keeps the pumps calibrated, so a pump that drifts is caught and corrected.
A drum stands on a scale that reads during the feed, so that pump calibrates as it goes and helps calibrate the rest. If a pump drifts, the scale catches it.
Pump speed comes off the live flow reading, not a clock. Slow the line and every pump slows with it, so the strength stays where you set it.
A long run gets a nutrient push the whole way through, so the feed still lands in the room. A long line costs water, never nutrient.
