lol actually im not a 100% sure what stress really is, all i know is that on the streets its cheaper and weaker than kush or chronic. usually the buds are browner and more dense. we call it "poor smoker's weed". i planted it just for the hell of it cause im a first time grower and i just wanted to practice with it. then i got that kush seed (grandaddy i think) about a week later. so im hoping that at least ONE of them is a female. your guess at what a stress seed is sounds realistic though.
