I'm also a complete asshole but everyone here already shat all over the place.
So I will answer you straight up.
Your homedepot buckets will do just fine. Poke some holes in the bottom. Or don't. It won't matter. Good chance you are going to kill the plants regardless.
Everyone has their own preference, but they seem to work equally well for the people who like 'em. Just make sure they have plenty of ventilation (sides and bottom) for drainage and also allow some oxygen make contact with the roots. I use 5g bags, but would have no trouble with buckets or air pots or whatever.
