The better part of growth habit is determined by genetics, and cultural conditions other than the chemical make-up of the soil solution, though there are synthetic chemical growth regulators that can alter growth habit. The word overkill comes to mind in the face of the idea that buying seeds of a stouter variety would be a lot easier and potentially safer - who wants to eat synthetic chemicals that alter growth in plants?

turtleturtlemeow, you might consider purchasing seeds of a variety that appeals to you.LINK

I already have seeds and I'd rather not waste them if possible.
