ive grown all of these and id say depending on which pheno u have master kush and og kush are going to be either ranked 1 or 2.. hindu kush i put in third place regardless.. its just run of the mill.. low yielding. og kush can yield fat, and once again depending on which cut u have, the traits will be different but most all og kushes are fire. master kush is fire also. very kushy tasting and a great middle of the line high.. doesnt put u to sleep. i personally have master og kush.. so i get the best of both worlds, and i love it. i can smoke this stuff all day and function and be pain free. really good for my anxiety also. not to mention it is done in 9 weeks, and i am getting around 6oz a plant indoor. running 4 plants under a 1k.
