its just like any other product. To make something good takes more time, care, and most of all MONEY. The shit that comes out of Mexico is low THC because it is grown in mass quantities, by people who don't give a shit, for the sole purpose of profit. The bud we smoke (at least around here) is grown by obsessive pot enthusiasts. These guys are no joke. Strains are carefully documented, growing conditions are optimized, and as a result they produce an amazing product. Really, this should be fairly obvious to everyone here. Apply it to software if it makes more sense to you that way.
