Project Introduction and Overview:

Sour Crack, love or hate the name is one of our fastest and most popular varieties. We feel she is one of our flagship cultivars and really broke ground and gained traction with the idea of connoisseur automatics. Sour Crack is a perfect sea-of-green machine, one of the frostiest varieties in the Mephisto arsenal and is a very useful strain to have in your auto-toolbox. Not only is she lightning fast but it is extremely resinous and potent to match. Mephisto Genetics was looking for a strain for stealthy quick runs, that could double as a commercial quality autoflower with a connoisseur flavour profile. Both of her photoperiod parents are extremely fast and frosty varieties. The Green Crack has the rush high, and the 24 Carat has the Afghan couchlock effect, together they make an incredibly powerful yet well-rounded effect. Sour Crack has been used as the auto parent of many strains down the years including our Artisanal strains Sour Stomper & Sour Livers, and our Limited Edition White Crack. Sour Crack truly is a cracking variety. ...I'll let myself out.

Strain behaviour and structure:

Sour Crack, being a fast strain, has a short seedling stage and as soon as she sexes there's a small time period of extra veg/stretch growth before switching hard into flower mode. Frost levels are very high, trichome development is apparent from early on and she quickly makes chunky dense buds that are dripping in resin. Consequently, Sour Crack makes a beautiful extraction/hash plant to work with. Commercially, she can be taken as little as 55 days from sprout, but for the connoisseur auto grower and toker, 60-65 days is more accurate depending on the exact effect the grower wants. She's an auto akin to the reason we love autos! Sour Crack doesn’t want for much, take care of her, watch the amazing daily progression before your eyes and the rewards will soon come. Sour Crack works fantastically as an autoflower sea-of-green strain, for really above-average yields. Having dense buds and being a short stature plant with thick foliage, she’s not best suited for outdoors unless you’re in an arid climate.
