I'm with lastpirate on this. First, it really doesn't matter the size of the plants. We've got a redwood that, if you asked me, would be about 10' tall. But, you ask my son or husband (son's 6' tall, hubby's about 5'10") and they'll tell you she's 12', EASY. Maybe it's all in your perspective. But, y'all can't say it's impossible and that you have to have all these pre-conditions. How would you explain what BLT manages to grow? Search for his threads, he's got some true monsters.
Also, Dobbiegirl just doesn't strike me as the "bullshit to get attention" type, just from the little I've read and all. Just sayin'.
