Grade 10 Auto

Grade 10 is a feminised autoflower from Mephisto Genetics, bred by pairing Samsquanch OG with Schoolyard Crush. Schoolyard Crush itself combines High School Sweetheart (Gage Green Group) with Mephisto’s Sour Stomper. Introduced in February 2025 as part of the Schoolyard Crush Limited Edition F1 lineup, Grade 10 is sold exclusively in 5‑seed packs on the official store. The breeder lists it as a 60/40 indica/sativa hybrid and describes plants as mid‑sized with dense budsites. The flavour profile is noted as sweetness with earthy undertones. As with the other Schoolyard Crush F1 Limited Editions, Mephisto states these crosses are untested beyond their standard germination and quality control procedures, and links certificates of analysis on the product page for reference.
