Additionally, a cubensis strain that may be worth your while to look into (for potency, quality, and yield) is the Ecuadorian cubensis strain. This is not only one of the top producers of known cubensis strains, but also yields beautiful fruits that, in my humble opinion, offer some of the most colorful and intense visuals that I've experienced from the 20 or so strains of cubensis that I've worked with or may currently be working with.
