Thanks for the diagram. That clears things up very well. I was worried about the contact point between the hardware cloth and the rggs frame. I still worry about hardware cloth breaking in a few seasons. If it does, it should be easy to staple a new one there.
The 2x4 - I thought that the 5/4 cedar decking planks were 2x4 lumber.
I might go with 1x8 or 1x10 instead to get more depth
Also, those net cups from local hydroponics store work great. They are about dollar a piece. Only reason I asked is, I saw some yogurt cups in one of the images next to your rig
I think I will try to build it for this season. It seems easy enough. I am planning to go with the pipe. Wife is always very worried about open standing water.
Also at the moment, i will keep filling up the water reservoir instead of using a valve. Not sure how I can introduce right amount of liquid fertilizer in the valve based system
