Autoflower transplanting

You can start in small cups and pot up to the main pot. But that will slow your grow down and stress them , same with topping. Autos have a certain amount of time to grow unlike photoperiods. So any stress that you can avoid you should. That doesn't mean you cant. I've topped autos before and grown some big plants . But it may add an extra week or 2 on to to the grow. I think you should start in the final pots with autos but that's my preference. Topping isn't really needed if you know how to LST correctly . ✌️
