Hi boonleng, I've had a little 'slow-down' as this is a long holiday weekend in Thailand and the relay switches and the transformers for the pump power supplies have to be assembled in Bangkok and then shipped down to me.

I want to run the water systems for at least a few days before I start putting in/on the plants. The emitters for the wall system are on a pipe running along the top edge of the wall, wrapped in between layers of the capillary mat material. I'm thinking of changing my filtertank/water resevior to a much larger size so I don't have to worry about it pumping itself dry.
