THC Pro is Drenched in Resin & Packed with Couchlocking Power!

A special re-worked, East Coast hybrid of the world-renowned Chronic was combined with a selectively bred Northern lights, complementing the N.L lineage within the Chronic harmoniously. This strains durability and ability to cope with stress, mold and pest resistance are notable characteristics along with its powerful and fast behaviour and its explosively high THC laden buds.


Big Head Seeds then back crossed with their BigHead#1 for added yield and to encourage the spectacular central kola and minimal side branching that is typical of their signature strain.


The exceptional smell and taste of the East Coast Chronic is mind blowing and the dense buds are light green, tipped with bright orange hairs that contain consistently high THC levels.


The high is typically Indica and is very therapeutic, suiting anyone trying to conquer anxiety or insomnia issues. THC Pro oozes with high quality bag appeal and is a great choice for those looking for a big yielding, hard hitting, high THC strain that is easy to manage.
