How can i maximize my grow?

I started 12 feminized seeds and all sprouted 2 weeks so far, im planning to leave them thier for 2 more weeks, than i have to decide weather i should have 12 plants in 1 gallon pots or 4 plants in 5 gallon pots after the transplant i will vegg untill the room is filled side by side with leaves than flower. The strain im grower is the slowest growing indica on earth imo. Whats better for my yield? Kinda suck to trash 12 seeds i paid for.

1 pot per plant if in soil.

Yes I ment 12 individual 1 gallon pots vs 4 individual 5 gallon pots, sorry about the confusion

grow the 12 plants in a sog to make use of all of them and get a quicker grow

Do you have room to clone? If it was me I would go with the five gallon buckets then trim all lower branching and clone it to make up for any plants you do not end up keeping. 1 gallon pots imo would not be big enough to keep the plants growing for more than 1-1 1/2 months tops you want 1 gallon for every month the plant is alive. So with the 5 gallon pots your going to get the most out of your plants.
