UPDATE: Just found out while playing SMP that the Sugar Cane Observer isnt working right, since the piston right underneath isnt reacting. Ill Update this build asap. All one would have to do is to connect said piston to the redstone that runs along the cactus (on top, outside).
Let me know if you find something else, ill get it fixed. HF!

Ok, what Ill try is the following:
1: Get rid of the water (for now)
2. Place trap doors around the dirt blocks you got up there
3. Put the water inbetween the dirt platforms. Take care that its all flowing to the middle.
The dirt platforms would need to be at least 2 blocks high for this.
Hope this helped a little.
