Media Bed and Siphon

The Grow bed is done.
Tinkering with the ebb & dry system and diy bell siphon.

Didn't seemed to flush well so I tried with the p-trap siphon, still didn't flow out well.
After further reading and youtube search, found out the water vol in pvc gutter grow bed wasn't ideal enough for an efficient siphoning without further modification.

So back with the bell but with lower water level and now its flushing as expected. Lower water level intake will cause a shorter effective grow bed media depth. So I guess I have to choose what type of plants suitable for these setting.

Ebb & Dry systems done! Off with my sump systems next...
