Thanks for the head up. I've been using standard pots, but they are just not wide enough... I'm thinking about using dish tubs since they are relatively cheap.
I also use all kinds of strange vessels for planting. If it can hold soil and doesn't have holes, I'll use it. I grow a lot of viviparous ones, so I'm one of those folks who grows plants in the 10 oz plastic drinking cups... I started off with 3 oz ones and they work for some varieties, but too much repotting... The ones I sell are either in 6 inch pots or 32oz plastic containers transplanted from the 10oz ones.
