It actually is a technical hurdle because not a lot of academic research is being done on it for commercial growers to use. You see some papers out there that cover things like yield per light spectrum or what soil ammendments do for terpene content, but they all come out of Canada and specifically McGill. It's like U.S. researchers are blackballed by their institutions or maybe their grant funding agencies. As such, techniques like plant tissue culture that are commonly done with other crops and expensive ornamentals in the U.S. are rarely done with cannabis because growers that do these techniques are often tight lipped about things such as the most ideal media composition or really anything else related to methodology.

Meanwhile with crops such as corn, you have entire land grant universities planting test crops as we speak and biology departments dedicated to maize genetics, and thats true for almost every other large commercial crop. Billions are spent on research by the federal and state governments. Agriculture takes advantage of all of this research and development when producing commercial crops, but none of this investment is being made for cannabis and when it is done by these private companies they are not proliferating their findings.
