There are as many ways to control your tall sativa as there are growers. There's no way you can escape pruning, bending & tying. Shape & size of area will dictate how you do this. Read every thread you can find on lst & hst (low stress training, high stress training), topping & other pruning methods. You will always find more info than you ask for, this is peoples way of making sure you have all the info you NEED for your circumstance. After a while, you'll also see this is more than just a forum board to many, its like our second family & we're a little protective of our respected family members. ~~~PEACE~~~
