Nightingale is an Indica-dominant strain that is bred by crossing a Shiskaberry and the CBD-containing variety Candida. The test yielded CBD values of 11%, with some phenotypes of up to 20%. Nightingale is a more natural selection because THC levels are not yet stabilized. The CBD: THC ratio is in the range of 20: 1 to 1: 1. Suitable for medical use.
