could i use a long pot

could i use 1 of them long planters (the ones that go on railings) , it 6 inches wide by like 2 ft long. could i put like 2 or 3 plants in 1 pot? all the pots i have are being used already. should i just use like 2 liters or milk gallon jugs cut in half instead?

yeah i would use a milk jug instead your going to have to translpant them eventually and it wont be fun

yae ,that would be a bitch transplanting, i think il just go with the gallon jugs.
thanks
