I planted some tomatoes in the spring time, in some 10 inch pots. They grew, but remained pretty small. I was told it was because the pot was way too small.

Now I want to plant some broccoli, cauliflower, and romaine lettuce. How big of containers should I have? I live in an apartment complex, and only have a small porch! Would five gallon buckets work?

Also, I was wanting to grow some radishes. If I got a long rectangular box, about 10 inches deep, 10 inches wide, and 30 inches long, would it be big enough? Radishes interest me because they are so quick to mature.

Thanks!
