On physical quality, reviewers mention good moisture and stickiness, smaller buds or weaker bag appeal, and milder-than-expected potency. Sensory notes include a pronounced berry/cheese/cookie aroma and similar character on the palate.

Ultra Sour is a community-tracked medical cannabis cultivar distributed in the UK by 4C Labs (grown by Sundial). Patients report it is commonly used for various conditions. All reviews on CanVerify are tied to specific batch numbers so you can see how quality varies between harvests.
Community reviews reflect individual patient experiences, not clinical trials. Effects vary by person, batch, and condition. Do not start, stop, or change treatment based on this site alone.
