Bubba Pupil is our new heavy Indica pupil cross. She will glue a smile to your face instantly! This strain takes the best traits of both parents, with the warm cozy body blanketed feel of the Bubba Kush, combined with the extremely positive, uplifted, happy, trippy mindset from the Star Pupil! A perfect mix of super clean head high, fuzzy body medicated, and gently psychedelic trippy high vibes, coated in ultimate positivity and happiness! This is the ultimate choice for medicinal effect, positivity, functional relaxation and pain relief, with an intense strong happy stone. Expect extreme potency and high yield of delicious flowers with sweet bubba chocolatey coffee and pupil funk mixed right together for a beautiful expression of combinations of both parents. Copious trichome production and powerful aroma and flavor. This plant is extremely euphoric and has a really perfect, magical headspace familiar to all Pupil crosses!

The Bubba Pupil and Katsu Pupil are two sister strains created by Mass Medical Strains and Katsu Seeds. Mass Medical Strains was gifted the Pre 98 Bubba Kush and Katsu Bubba Kush from Katsu in order to create two heavy Indica hybrids by crossing each with our signature Star Pupil, adding purple, pupil vibes, and hybrid vigor to these two versions of Bubba Kush which have stood the test of time as some of the world’s best Indica flowers. We are honored to work together on these collaborations to bring some very special Indica dominant plants to the world.
