If you do top it's best to get them when they're very young so the split will be low and it gives the plant plenty of time to recover. I usually pinch off the 4th or 5th node as soon as it is pinchable. This way you can train both stems resulting from it to grow in two opposite directions. Once several inches have grown on each stem I take a 1" thick strip of duct tape and wrap it around the trunk where the split begins to stop it from tearing once the training begins.
madeline Reviewed by madeline on . LST (low stress training) lots of people ask what is LST and how is it done, what does it do in the end. LST is a training technique to keep the plant short and expose more light to lower branches, if trained enough you can create a very even canopy and grow denser buds. you can start LST at about 3 weeks into the veg stage, make sure your plant was watered the day before or at least an hour before attempting as a dry plant will break very easily. what you want to do is secure the stalk and loop something over Rating: 5
