Hey Guys,



Here is my preliminary designs for a training system I am going to setup for a non-profit group. This group is going to use this to help teach the under-employed or unemployed how to grow fresh fish and veggies, in conjunction with a solar class I am teaching.

The large tank on the bottom is a Rubbermaid 300 gallon stock tank, and the tanks on top are 3 50 gallon Rubbermaid stock tanks.

This system is going to be indoors. We are going to use fluorescent T8 lamps for the grow-beds and grow mostly greens and herbs to start.

I was also planning on using this pump http://www.hydrowholesale.com/Submer...mp-700-GPH.asp

I am also planning on experimenting with venturi's on the intake and outlets. Has anyone tried to add the venturi to a bell siphon drain outlet?

I am wondering if I should have a sump tank, if so what gallon size? What are the pro's and con's of not having a sump?

Any suggestions would be great.

Update: Changed the 2x4's to 2x6's and added OSB pieces for lateral support and I changed to the Danner MD12 http://www.aquaticeco.com/subcategor...ag-Drive-Pumps pump. We may test different grow medium one with hydroton, expanded shale and then cheap river rock.
