alohacynthia, I was just reseraching grants for this earlier this evening for our state and they go up to $15,000 for the individual farmers. I think, but am not sure that a commerical unit may cost out at $11k but that doesn't include a good back up Honda electric start generator at around $1800. I was going to do up a cost analysis for a smaller family size version as well. We are working with Tim on a family size unit tomorrow so I will be checking that out. Pumps and such are still going to be the same cost.

When I get the rest of the info together I'll post it here. I aslo have the parts list I can post here for the commerical unit. The tanks are amazingly easy as they are just plywood covered in fiber glass (inside and out) and then painted. For an 8 by 4 foot tank (one for the fish and one for the sump pump) it is around $300 each. Not to bad. We made one tank up in a day. Tanks need to be 4' deep because the fish jump and they also like the deeper water to swim down too. Water hycinth can also be used on the fish water surface. Once I get this week behind me I'll start posting more info on this.. and the roof top garden info as well.

I just need to transcribe my notes into text.
