Hi
@Autofeather! The sooner you start, the better control you'll have over its shape. However, LST on seedlings is not a good idea, plant should have a strong root system and stems must have a few centimeters to work with. From what I see on your pictures, you're in the perfect timeframe for a first LST session. Here's my method with AirPots: 1 string around the container, then X strings to tie your stems, fixed to the container's one. Keep up the great work with this beautiful lady 👊
