How close can plants be if theyre in one long pot

i just started growing for the first time and i planted 6 seeds 1 headies and 1 middies right next to each other in about a 3 foot long pot ive alrdy got plants starting to grow but i was wondering if there so close together are they evenually going to weed each other out or will they all grow

get different pots for them. then they can be as close as you want.

You might loose some or all if you transplant. They will grow, run them 12/12 from seed with no veg or they will choke eachother out if you veg at all. Don't do this again.
