Cannatonic, also known as CBD Queen, is a hybrid of Spanish resin seeds. Cannatonic was reportedly introduced around 2008 and is one of the first varieties with a high CBD content. Cannatonic is a cross between Reina Madre and NYC Diesel.
The strain took third place among the Sativa strains at the 2008 High Times Cannabis Cup and is recommended mainly for medical use. The seed bank offers three main phenotypes of the strain – one with a 1:1 THC-CBD ratio, one with high CBD and low THC, and one with high THC-CBD.
