So I've grown it and sucked. I've been gifted seeds from Nirvana of Master Kush on three occasions, all three were the exact same phenos. No smell.. (master kush is known to be a low odor strain) Smell is extremely important to me. And it didn't yield good so it was phased out everytime.
Every single strain I've grown from Nirvana sucked ass (made unbelievably great shatter tho)
I've grown NYPD, Blue cheese, White widow, master kush and a couple others I can't remember..
But I hear they have got better..
I have an 8th of master kush from a dispensary and it's fire.. So I think pheno hunting will be a must..
