Gorilla Glue #4Mythic OG

Description

Very sticky and pungent sativa-dominant auto displaying great vigour.

Grease Gun Auto is a 60% sativa hybrid of Gorilla Glue and Mythic OG. It is a highly vigorous strain that takes longer from seed to harvest than other Atlas Seed autos. Grease Gun Auto has reasonable mould resistance and good tolerance to both cold and drought. Atlas Seed claims between 99.9% - 99.96% female plants from these auto-flowering seeds.

Grease Gun Auto takes 80 days, or thereabouts, to go from seed to harvest with plants ending up at 100 cm. tall. Plants are well-branched and yield between 90 - 125 gr. each. The buds are extremely resinous, large and very dense as well.

The terpene profile produces scents of fuel, citrus, chem and dank/funk. THC content is between 17 - 26% with very low CBD of 0.05%.
