Hey MnNice,
I think you will be okay with LST just be very gentle and don’t over do it in the first day of training. I prefer to just let them grow and then pull back/tie out branches to open up the 🌲. If your using felt pots, plant Velcro works great because you can just Velcro right to the side of the pot. Check out my latest diary and if you have any questions I’ll be glad to answer.
Happy growventures :)
