if your growing outside then i would get some good dirt in the 5-10 gallon pots,make sure you have good drainage and some decent nutes of your choice.the good thing about outdoors is that mother nature does all the work for you.just make sure rabbits and deer dont eat your crop.use some chicken wire for the rabbits and use fish string for the deer.theyll feel the fish line but cant see it so they wont try to jump it.anymore questions,just ask
