When to transplant solomatic seedlings to their fi...

Is it a autoflower? A autoflower should be planted in a big pot so you don’t need to transplant it. They don’t like stress and stop growing for some time. I transplanted 1 auto when it was about your size because I didn’t want to hurt her roots. She’s doing fine now in her 25L pot. If it isn’t an autoflower you can wait till it’s a bit stronger and the weather gets nicer. They grow longer so they don’t minda little transplant stress.
