Description
K.O. Kush by heavyweight Seeds is a strain made to get you extra stoned; it’s a fusion of Afghani, hash Plant and Northern Lights. This plant is perfect for those that love strong, long-lasting effects – it can be grown both indoors and outdoors. Its bud/leaf ratio makes it easy to trim when it’s time to dry the flowers.
Indoors it grows tall and wide, which is perfect for light absorption. It grows out long branches that grow upwards towards the central calyx, meaning that these plants are quite balanced in as far as yield. With just 4 plants per square meter you can grow a sort of natural SCRoG that can give impressive yields. The central calyx is where most of the flowers grow, but the branches also grow some dense, highly resinous buds. After just 8 flowering weeks it’ll be ready to harvest, producing up to 500g easily per square meter.
Outdoors it does wonderfully, adapting to pretty much any climate you grow it in. This strain is highly resistant to rot, so even if you grow somewhere that you know other strains have suffered rot, it should be okay. It’ll be ready to harvest towards the end of September/beginning of October.
It has a sweet, earthy flavor with a delicious hash aftertaste. This plant produces a whole lot of resin, even on the largest leaves, so you can make your own extracts. It has quite an intense, narcotic effect, perfect for treating insomnia and nerves. It’s also great for calming the mind and dealing with muscle pain.

What a beast! The yield is insane, just like they say. And the aroma... oof, brutal. Has anyone tried it outdoors with topping?
Translated from Spanish
¡Menuda bestia! La producción es una locura, como dicen por ahí. Y el aroma... uff, brutal. ¿Alguien la ha probado en exterior con poda apical?
