Cataract Kush is a connoisseur-grade indica that novices can grow with great results. Even though they can grow this plant easily, they may want to read the warning label first. The Cataract is so named because it brings on the squinty-eyed, Mr. Magoo stone that penetrates deep into the body. This is a heavy stone that creeps up about ten minutes after smoking and keeps building in intensity long after the smoking has ended. Combine that with the creeper effect, and it can cause serious couchlock for uninitiated. Lightweight smokers may have an unpleasant experience if unprepared, but those who are after the big stone indica will be pleased with the hashy, spicy-sweet flavor that brings the rich pungency of Eastern spices. Medical users will enjoy this strain's usefulness for pain relief, encouragement of appetite, and assistance with sleep.
