the agriculture buisness

[Danny]

I am a college student learing about the agriculture buisness. A project of mine is to set up a working buisness plan for a commercial hydroponic tomato greenhouse. Because of the extreme amount of information on the web I am having trouble locating reliable information on expected typical yeilds, and about average timing from propagation of seed to harvest. If anyone can help locate this information it would be very helpful. Thank you. Danny
