Err, I think voting should be limited to selecting the top three, that way the persons on the bottom won't be hurt. Plus those results are the only ones that matter.
I think that rule number nine should be changed or remain the same. I think that if someone has a flowering sized rajah they probably have something else nice they can enter and they would avoid entering the same plant twice.
I think the six month rule is great, I think it allows the true skill of the grower to be seen.
