Hmmm.. I'm going to have to disagree. I wrote this post as an informative one and not to get to deeply into the details of growing. However, I don't think it's fair to say that all cornfield grows yield a terrible product. In fact, I think you're totally incorrect.
For example, there are a lot of "master growers" who yield terrible products due to chemical use and numerous other factors. Moreover, many of them are even doing this in a totally controlled environment, indoors. Does that mean everyone is doing it wrong? Of course not.
Surely, there are concerns with pesticides and fertilizers present in cornfields, but that's not always the case and just like in any other situation, there's always a solution. Just because some people in Europe don't know how to properly sex their crop doesn't mean that others in Europe (or around the world) aren't doing it properly. My final product is always high-quality sinsemilla because I pull my males and because I don't plant in areas where others grow. So, I find your argument to be totally invalid as far as quality is concerned.
Furthermore, just because corn is a heavy feeder doesn't mean that cannabis is incompatible for growing in the same space. If you run Sativas (especially a tropical sativa), which you should know are lighter feeders as compared to indicas, it's rare to see a deficiency problem and they'll also easily outgrow the corn without even breaking a sweat - it's in their nature. As far as roots are concerned, that's a complete non-issue.
You may have based your apprenticeship on cannabis as a companion crop, but that's not what my article is about. My article is not geared toward long-term soil maintenance of cornfields, nor is it geared toward the mutual benefits of corn and cannabis. I'm not talking about running 500 plants in a 5 acre cornfield. My article is about growing a handful of cannabis plants, for personal use, secretively, in an extremely large cornfield. I'd say 90% of cannabis that's grown and sold is motivated by profit in one fashion or another, so I can't relate to or agree with what you seem to be hinting at - that growing in the corn is damaging eco-systems and putting dangerous, unhealthy, garbage quality cannabis out there for nothing more than a quick buck.... That's simply untrue.
I say everything above with respect, and I respect your opinion and the time you took to write your comment. You raise some rather interesting points, however, it just doesn't seem to be a very relevant or valid argument for the situation I'm presenting here in this particular article.
