Under 21% THC strains

Just started MC with CB1 medical. (Disappointed with lack of menu but will put that in a separate post) but since I’m not able to be prescribed anything over 21% THC im just looking to find recommended strains as I’m a beginner as well. So far I’ve had big narstie golden runtz (T20 I think) as my general daytime strain and it’s INCREDIBLE- usually I have a very silly high and get couch locked but this made me very functional and eased my symptoms.

I’m getting tripoli next for my nighttime strain, but wanting to branch out a bit. I’ve heard lavender cake is good. Any suggestions?
