I should also add that a lot does depend on how a given genetic is grown. I recently had the pleasure of sampling some varieties grown under plasma, and I had to say I was very impressed. The extra light spectrum maybe does indeed boost effect. Other times I have been with a group of people sampling a particular variety and I have noticed that some in the room loved the variety and another couple were unimpressed. So I am convinced that there is a 'personal taste' angle to the argument, I think our own endo cannabinoid systems may allow us all to respond in a different way to cannabis. Which is why I remain a great believer in the home grower trying a range of genetics, and harvesting them at a range of times (early, middle, late) to see what they like and when they like it chopping.
CBD-rich varieties are a good example. Some customers swear they will never grow anything else, others say that they just don't rate them.
Its a big difference from alcohol where you can pay as much as you want and make the process as complicated as you like, but you still end up with ethanol only. With cannabis we have the multitude of cannabinoids, some amplify the effects of other cannabinoids.
