First time growing autos, how big (soil) pots to use?

Howdy greencowboys!

How big pots do you use to go with when growing autos?
Are 3.6 liter enough or do I need to go bigger?
The soil im using are bought in the hydro store and should be allight. Also i have canna for nutrients if i need. Maybe if I go with 10 litres i do allright without nutrients?

3.6L works fine... but the question is how tall and how much you want them to yield? If i had space id go with 10L pots, atleast 7L, why dont you wanna use nutrients at all? Ofc they will be fine but Just give them PK 13/14 in bloom they should be fine in soil without anything else, (you will be better off with a full nute run if you know how to use them properly ofc)

My last pic in my grow log was a plant grown in 1L pot, but it also had weak lights, to give you a picture of the size
