Shagrathanswered grow question 4 years ago Hi there!
LST is very simple technique 'cos you can start it early or late and the results are pretty same. I suggest that the plant should have atleast 6 nodes before starting.
The idea is to bend the main branch down to promote the growth of the lower branches and this is happening because of the plant hormones
When one branch is top it has auxin and when you bend it under the other tops the auxin transfers to other branches to give them sign to be the new tops. This is why LSTY workjs like it works
