If you're using LST techniques on your indoor plants, you'll need to create holes in the sides of your pots to allow you to insert the strings and pull down the branch. If you're growing outdoors, you'll need to attach the line to a stake and drive it into the ground. As mentioned, make sure you leave a gap in the loop around the branch. Tightening the string prevents nutrients from getting to the tips of the branch, choking the life out of your plant. Using LST in combination with scrogging ensures you keep your training on track if you're growing indoors.
