Parts required
For lower level (H1)
- 1x Large black watering tray
- 1x Drain spigot
- 1x Clear PVC pipe
When extensions are used (H2 / H3):
- 1x Drain pipe (black tube with elbow)
- 1x Feed hose cover (black tube, no elbow)
Process
For the bottom level only, push the clear plastic pipe onto the spigot. This pipe channels the water back into the tank while reducing noise. If you are happy with a bit of water draining noise, leave it off for more water oxygenation.
Push a drain spigot into each watering tray, with the slot in the spigot lining up with the slot in the tray.
Place the watering trays into each of your grow levels, with the holes on the right.
Only for grow levels with another level above them:
Fit a drain pipe (with the elbow at the bottom) between each tray. The top end of the drain goes over the spigot, and the elbow at the bottom of the drain points away from you if you are in front of the system.
Fit a feed hose cover between the trays, in front of the drain pipe.

When a mid-tier extra level is fitted, use the shorter drain pipes and covers:
