Earthboxes are what I use for container gardening and I just love them. Those folks really should put me on the payroll. I've sold _lots_ of those boxes because I tell everyone about them that grows in containers. Everyone I know that has tried them, _loves_ them!
I like container's also..But I like free or cheap one's.. I use a lot of bushel basket's and 5 gallon buckets we have lying around here on the farm.. The bushel baskets are great for tomatoes, eggplant & peppers.
I think the earthboxes are probably great too. But they are very expensive! So I am using $5.00 pots from WalMart and filling them with Shultz potting soil at $7.44 for 2 cu. ft. bag. So far, I have the best looking tomato plants on the block:) Have planted 91 tomato plants this spring, including 36 different "heirloom" varieties. All are doing very well so far in the containers. Keeping my fingers crossed:)
