xcrispi makes a very good point- topping really helps the sativa sisters. I topped my blue haze triplets twice, as well as lsted, and they never got over 3 ft tall, but were at least 2 1/2 feet wide at harvest. The same is true for the two ppp I have in flower now (will post pics in my grow log today)- if anything, I have to be careful not to let the girls get to fat, or they outgrow the flowercave!
