people might know i have colombian hed haze flo is quite long.. to grow to get some smoke and seeds . how tall would the plant be if a started flowering from seed ?

the colombian red haze is about 80% sativa

If you put the plant in a 12/12 cycle right from seedling?? No. Don't do that. Take an educated guess. Are you saying that you already have a plant growing or that you have seeds from a bag of the columbian red haze.
