I'm being a bit facetious. Only people who sell drugs for a living, where the price is artificially inflated by the government, can have that type of slash and burn philosophy in a mature market... Most pot growers don't even try to save money on overhead, but will cut corners on safety. I recently saw an HPS guy trying to use a 100A breaker for a circuit rated for a lot less. This is a dirty industry, and people can be very profitable still, even with the competition. You want to see competition? Let my state grow it too! We'll take an oz of weed to the price of an oz of cheese. That's why they still buy premixed nutrients, even for larger operations. It would "only" save them a few thousand a season to use DIY nutrients, for example. only.
