Madness is the name given to several very different strains, including those offered by World of Seeds and Hazeman Seeds. Other strains that include the word madness in their names are Manitoba Madness and Mendocino Madness. Thus, the "Madness" strain from your local dispensary could range from heavy Indica to heavy Sativa, depending on where you purchase it.
The Madness strain from World of Seeds was developed over several years but began with a group of hybrid clones from Southern Brazil. Some of those clones were bred with some homogenous male Cinderella 99 and Matanuska Tundra plants. Traditionally 50% Sativa and 50% Indica, Madness from World of Seeds features heavy physical and high-flying cerebral sensations. Its narcotic-like bodily effects are used to treat insomnia, chronic pain, and muscle spasms. The cerebral effects may ease symptoms of mood disorders and chronic stress.
The strain from Hazeman Seeds is almost entirely Indica and is a cross between Bubba Kush, popular before 1998, and the Sensi Seeds' strain G-13 HP. This Madness starts with a brief cerebral effect and soon moves to the body. Like the World of Seeds' strain, this version may also help users sleep and soothe pains and spasms.
Both strains carry a THC count of 14% or more and require eight to nine weeks to finish creating their frosty buds. While the World of Seeds' version is very easy to grow, the Hazeman Seeds' strain requires some experience. The strain from World of Seeds is resistant to mold and temperature fluctuations, making it a good choice for a greenhouse. Outdoors, Madness from World of Seeds is usually ready in late September, but the Hazeman Seeds strain may need until the middle of October. The World of Seeds strain may yield up to 500 grams.
