She's a beauty! My plant is just 3' tall. So I won't get as much as you will. Still, I don't think that I did too bad considering that this is my first time growing all the way to harvest time. Also got a late start, since I got the seeds on May 17.
Try one of the advertisers on here. The Vault, might be a good place to start, they seem to be the most active of the advertisers. At least as far as seed companies go.
