Wash it well before using it- plastics often have nasty oils on them. And put holes in the bottom for drainage.
why not plant directly in the earth and use good soil to start the plant in u wont be able to move a full grown plant in a 6 gal bucket of dirt anyway
bongboi, why have your plant in a pot? Well, for a start, where I live, we had snow in May and June this year! Granny
