I agree, I'm just interested in growing good produce for our local community at this point. I'm just not really interested or setup for competition at this point. Fact is there isn't even enough hydro growers in our area to even have any competition. Where I live I'm more concerned with promoting hydroponics for something other than growing pot. Though I get the point, any competition for growing any produce (NOT pot) would be good advertising for hydroponics in general. Though I think the idea is a good one, and I would completely support/promote it as much as I could. In the future when things are going better for me, I may even take your lead/idea and run some type of hydroponics (Not pot) competition.
I know of the tomato tree at Epcot you refer to. In fact Simon posted pictures of it in one of his albums.
