The odor comes from a type of terpene that is a highly heritable trait that is already highly variable. (responsible for all the wild flavors and smells of some strains) Getting it to switch off without gene splicing is just paying attention to randomness and breeding the outliers. I stumbled on the characteristic by outcrossing plants that had been treated with a mutagenic. It would be expensive to waste so many plants, the failures, for a commercial enterprise, but mine is a hobby, sort of like someone developing a type of rose.
I will have to ask a neighbor what the the proper Chicago Chakra crystal would be. I don't follow that stuff, but it is almost like its own language out here among the practicioners. Reiki healers are a dime a dozen even in the redneck towns.
