Mephisto Genetics consists of a small team of growers who have moved to Spain to concentrate on creating excellent autoflowering varieties. With Sour Crack they have crossed their popular autoflowering 24 Carat with a version of their own Green Crack which was in the developmental stages of becoming an auto. After breeding out the offspring for at least three generations to become stable we are left with Sour Crack. Sour Crack is a fast auto. She should be ready in just 8 weeks from the onset of flowering. If you leave her 9 weeks you will get a much heavier stone; 8 weeks gives a nice hybrid hit with a more sativa type head buzz. Sour Crack is real easy to grow. Mephisto recommend starting her off on a light soil in a 1 litre pot. Transplant her up to an 11 litre pot and start feeding after the onset of flowering. Keep the lights on 18/6 for the duration of the grow. Although Sour Crack plants stay fairly small, buds are very dense and a great calyx to leaf ratio makes them easy to manicure. Sour Crack is a good quality automatic strain from people who know all about autos.
