Mr E S1 is a very special collaboration seed line between Mass Medical Strains and Eastcoasterdam. The purpose of this seed line is to preserve the Clone Only Mr. E strain in pure seed form with no outside genetics added in. 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.
