In this important year for us when we celebrate 10 years of dedication and hard work to offer you the best genetics, the World of Seeds Team is proud to present our first high CBD strain.

Called CBD Tonic, this strain is the result of crossing and selecting a Critical Mass with a Diesel Tonic. 


Critical Mass is one of the most popular strains for its speed, effect and yields and we’ve crossed this with Diesel Tonic, which is, in itself, a high quality hybrid created by crossing the well known genetics of Cannatonic with NYC Diesel.

The resulting plant is very easy to grow, ideal for all types of growers with yields approaching 1g per Watt, very productive and very little efffort will generate huge rewards.

Cbd Tonic has a fruity citrus taste that is quite intense so smoking it is a real treat for your taste buds though the effect is peculiarly mild so that you can still easily undertake any task you put your mind to.


With a THC:CBD ratio of 1:2 and significantly higher levels of CBD than THC, this plant is suitable for treating stress and anxiety disorders.
