Best Pots size for indica Plants

Could anyone tell me the best size pots for indica strain I no they are still alot of strains and depends but on average what size is the best from the vegitaion all troughout the flowering soil based obviously

and as in size I mean in cm or inches not gallons or liters please this would really help

Depends SOG ( plants 2-3 ft ) 6.5liter pots ( 20cmx20cm) ... i think

i use 5gal for veg and bloom for nice 3-4ft bushes but seeing as your asking for inches i would think 12" "color pot" plastic patio would do good
