I have done quite a bit of searching around in regards to the Portable farms system. Short of calling them it was indeed difficult to find a price. Their system or one like it really appeals to me and i did quite a bit of looking around. about 2 afternoons' worth heh.
BUT in doing so
I did however find a place that listed the price for the two smallest systems...http://www.thefuelman.com/Super_fuel_crops/portablefarm.html
6'x8' = 1999.00 - 400 veggies 100lb fish
10'x20' = 2999.00 - 1100 veggies 400lb fish
I really considering this guys system or building/getting info to build my own. I live on the East Coast, basically in the Poconos' of Pennsylvania so the winters are freezy cold and snow filled. There are 4 different ski resorts within an hour drive of my house. So, I would more then likely need, a super heated green house (with grow lights)or a heated basement system with grow lights. Currently I am leaning towards a basement system, as it would require less initial cost for building and for heating.
I don't care that fish don't fart, I do care that they don't make noise, and they won't have nasty mercury and stuff in them so I could eat the almost every day! Instead of only once or twice a week "to be safe"
Oh yea, the other thing I would love to know about is how successful were/are these "Portable Farms" in the North East or better yet a Basement in the North East. That being the probable location where I live, as building a green house and heating / insulating it would be mandatory and also add substantially to the cost of any system I would build or buy.
All of the examples listed were in super sunny warm southern Cali.
