Ok, tanks, anyhow, I found some good info on sativa strains at the OG site. they do require special care and different nute requirements. sativa's have a different amount of chloraphyl than an indica strain. they are slower to flower and dont yeild quite as much, but the bud is supposed to be better. I need to look into this yo-yo thing i read about. i got 3 branches almost hanging straight down towards the floor now. this plant is a challenge.
