Step 4The Troughs - supply end
The nutrient supply will enter through the end cap on the high end of the trough.
1. The nutrient supply hose (1/4" drip line / sprinkler hose) will be held in place by a grommet in the end cap. We will determine which grommet to use based on the wall thickness of the end cap.
2. An 11/32" hole is drilled through the cap, deburred, and the smaller grommet is selected.
3. The grommet is then installed in the hole to provide retention for the supply line. You are looking at the inside of the end cap.
