Hydroponic Gardening

I am still very interested in learning more about this subject. Who knows?.... I might want to make and sell systems.

There are at least three systems ranging from a flooded system , to one using small tubing , to a wet spray system. At the moment I prefer the wet spray or air system for growth due to decreased water useage and greater growth rates.

I just like the idea of fresh vegetables and berries year round.

$500 for a small system....$1000 for a larger.

ideas?
thanks
