1-gallon (trade gallon) thermoformed/co-extruded/euro nursery pots. These pots are the thin but long-lasting pots, with holes only in the bottom, like Proven Winners plants come in. I really like these types of pots because they hold up well in the sun and tend to last a long time with use. I really don't need more blow-mold (standard cheap pots that break down pretty quickly) right now.
