Transplant auto at week 6

With a smooth plastic pot like that transplanting should be easy. Ordinarily I would say it should be very root bound and the whole thing should just pull right out so you can stick it in a new pot with little disturbance. Your plant is really small so at this point I would leave it in that pot since you are already into flower. I know some say auto's can be done in small pots but 8 liter is really tiny. My auto's in 20 liter fabric pots are a total, solid mass of roots by the end of the grow and could probably use even bigger pots. You can't get big yields from tiny plants.

Hi mate, I don't think that is a good idea. Autos do not like to be transplanted. She is well established into flowering stage and any stress will hurt your yield. You're doing great so carry on as you are, she will be fine in that pot. Good luck and happy growing
