I see. So your fruiting plants, like tomato, pepper, eggplant, celery, and broccoli need a square foot of space minimum. If your round containers are that big, you could plant them in those containers. You'll have to read about the cucumbers. If they are the bushing type, you could get away with planting them like the tomato or pepper plant, in a square foot BUT you're gonna have to give the plant more space. If the cucumber is a vining type, the plant will either need space to grow long vines or a trellis to grow up. I think your roots and herbs would work well in the 3' long container. So that would be the radishes, carrots, leeks, beets, turnips, etc. You should probably start those pods in a controlled environment, in the condo and then plant them in the containers maybe a week or so after the plants sprout. I've had better success going that route. You might also want to get some sort of a mulch, like shredded leaves, straw, DRIED grass clippings, shredded paper, to put on top the soil once you plant the plants to help maintain moisture in the containers.
