Plant Pot help

tomorrow im changing pots, i baught 12 litre buckets will this be enuff space for the rest of there lives? or will i neeed bigger pots

I think it would depend on how big they are when you put them in flower.

HMM I DUNNO I ONYL HAVE 6 PLANTS so i may grow em into bushes

I have been reading up on container size, the max you should need for a big plant is about 5 gallon (18-19 liter?) I'm using about the size container you bought and started 12/12 at about 17in.

ok so these 12 shud do for medium size plants im gonna vegh for 4 weeks, i dunno how big they be by then,

I veged for 4-5 weeks so that should be good. here are what mine look like 1 week into 12/12. https://www.rollitup.org/newbie-central/57954-second-grow-boys-girls-sorted.html
