Sour Crack is a cross of 24 carat and an Auto Green Crack in development, then bred out to be fully autoflowering. Both 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 is a Cracking variety (excuse the pun).

After tests and breeding development, Mephisto Genetics found it to be THE FASTEST auto they have ever grown..(and believe us they have grown A LOT of autos over the years). Not only is it lightning fast but it is extremely resinous and potent to match. Mephisto Genetics were looking for a strain for stealthy quick runs, that could double as a commercial quality Autoflower Sea of green variety. With restrictive potting, the plants stay short, entering the flowering period early, and speed like a train until the finish.

The flowers are rock hard, really easy to trim, great flower to leaf ratio, and showered with crystals. For an auto so fast you would expect there to be a compromise somewhere, but there really isn't.
