Good link, dill.
Although the plants look cool, I noticed a few of the posts through the pages mention that they 'almost got a normal yield', and that 'it didn't yield as much as I thought it would'... If anything I would have thoght the opposite. If more leaf area, more potential photosynthesis type of thing. But I personally have never noticed a difference.

I'm not sure playing with poisons and/or encouraging the plant's mutations is a great way to preserve the integrety of our seed stock long-term, and is a genetic influnce I'd rather avoid if possible. Cool experiment if it remains with the gardener, though. :thumbsup:
