Is there a way to grow a non-CBD strain to maximize the CBD?

Actually, there IS a way to do that... you'll want to harvest "late"... Here's an article I found which addresses that: https://www.growingmarijuanatips.com/the-difference-of-early-and-late-harvesting-of-marijuana/ In the article, this is what they point out: "The later time you will harvest marijuana, you will have more CBD content to smoke from the buds than THC. The tetrahydrocannabinol content present in the buds is lowered as they approach the late stage of maturity during the flowering time. "As the THC level of marijuana slowly drops the weight of the buds increases because of extra resin production. Late harvesting will benefit much those people who are growing weed for selling purposes and those who have much preference over a couchlock effect. The CBD content in the buds is higher during the late phase of bud maturity... "...Reap the buds early for high potency and cerebral high and do a late harvest if you want to experience a body buzz effect as you smoke the buds." Good luck!
