I find anything with good chem lineage to help me sleep, especially if it's left to flower for 12 weeks. My wife uses 1/2 cbd flower with either Hindu Kush or Gelato Cake to help her sleep all night. Tinctures are a great option for non smokers and act much faster than edibles.
You're 100% right. It's actually the same mechanism (THC conversion to CBN via light), just on the plant with terps over time.
