Mr E Pupil (Mr. E x Star Pupil)

Mr E Pupil is a very special collaboration hybrid between Mass Medical Strains and Eastcoasterdam. Our two flagship plants come together in this feminized hybrid for something super unique. This cross is structurally uniform, with some aromatic differences in phenotypes: some sweet Mr E dominant plants, some sweet with a bit more pupil influenced, and some oldschool roadkill skunk smelling phenos. Plants are high yielding and compact, with absolute top quality flower and high terpene content. This cross has shown excellent stability and production capabilities.

You all know Star Pupil already, but who is Mr E? As the name implies, the genetics behind Mr E are a mystery! A clone found and held by Eastcoasterdam for the last ten years, she is just an incredible plant. Stands the test of time for sure for him to keep her so long, and in my very first grow with her I instantly understood why. Simply perfect high quality flower, and great yields. A healthy growing plant after all those years, she has a pretty unique compact structure and can fit a LOT of yield in a small space! Perfect for micro growers as well who need to keep their plants small, but can be grown large if wanted. The high is strong and pleasureful, never “too strong” but has some real serious strength at the same time. It’s really enjoyable. This clone was given to MMS by Eastcoasterdam in order to breed with it so you can all enjoy the wonder of this unique plant. Some things about it lead us to believe it may be of the berry/lavender type family of strains, but we really dont know what exactly it is. Perceived smell/flavor varies from person to person. To me it goes from vanilla to green melon. Others say cantaloupe and more. A good descriptor is “good sweet pot” because that’s really what it is at it’s base. The smell of good weed and it’s sweet. MrE passes on good vibes and potency in her crosses. The MrE Pupil has some traits of both parents present, and is a really phenomenal hybrid of two totally unique cultivars.

Flavor: Some roadkill skunk, other more sweet, delicious, pupil tones over sweet melon.

Effect: Powerful and enjoyable high, the potential for both motivation and relaxing, introspective.

Flower Time: 9 weeks

Yield: High

Structure: Short, Compact, Bushy with Great Production. Best grown without topping.
