How to increase cbd in plants?

I was wondering if any buddy has any tips on how to increase the cbd % in a plant.

I believe that's really just by way of strain genetics and breeding so breeding hybrids with those properties is my thought. growing them a certain way won't make them pass their natural limit

so your going for a more of a pain relief , no way to do this the genetics a re the genetics but you can make it narcotic wich will put you to sleep just harvest 2 weeks later
