you could....but i wouldnt..its sort of a rule of growing cannabis that you do not want to grow several plants in one single container for soil grows. Cannabis plants and their roots are hungry for space, and if you have their root systems intertwining it could cause you some problems. Instead just grow 1 plant per pot, since they are autoflowers you could get away with growing them in smaller pots, like 32oz non-clear party cups for instance. I'd personally plant them in something thats atleast 1-2gals but that just my personal preference. If you wanted cheap tho the 32oz party cups would work pretty for what your wanting to do
