He he he, just you wait.
MNS, I was trying to be nice to him. Well, at least polite. It's hard to blame people with all of the misinformation.
I mean, he's planting them two inches apart and then trying to select for height while ignoring the fact stretching for competition would nullify the results. Not to mention plants that are too close together aren't going to get the airflow they need and mold spores would rapidly spread in that static environment further nullifying any results. On top of all of that he's using blunt force selection to try and homogenize (not trying to homogenize anything. In my first post I recommended the OP learning to live with it as it is.)the line, might take a couple decades to see results.
Trying to grow them in large numbers on a square meter each would most likely well, eh, get ya cought...
I dunno, does an architect get mad when he see's a kid playing in a sand box?
Or does he just think "aww, isn't that cute."
Rather the kid than beeing a snob.
