AA grade strains, also known as “dubs”, is good cannabis that offer a lot to consumers, and will fit within most people’s budgets. They are one of the lower grades or rating of marijuana that you will find in Canada, but they are still great for the casual user, and will definitely do the job for the majority of weed smokers. When compared with AAA or AAAA grades, the THC levels will be lower, and the bud sizes could be a bit smaller. A good choice for beginners or those who aren’t too picky about their weed.
