I used LST for the first time this week and it works better than I expected. Even though shes quite thin and not really growing any other stems except the mainstem. I water every two about with about 200-300ml. Overall though she seems very healthy.
Good Luck!
Stem with a plant height of 6 cm doesnt look too bad in my opinion. I think mine were a bit shorter at this stage, but not a lot. Maybe your "wind" is too strong? I did not let it blow directly on the plants at this stage.
@taprootArmy, Glad to hear. I'm quite worried about the stems lenght since it elongated so much in the first week.
I read online that setting up a fan at this stage would strenghten the stem. My second plant doesn't have any problems with shaking and she's in pretty much at the same stage.
