These containers look great. I bought two. They are sturdy, have wheels, and a unique watering system. The instructions are very detailed. I just filled the containers and added the potting mix, dolomite, and granular fertilizer. All watering is through a pipe that extends through a tray, and waters from the bottom. The top is sealed with a plastic liner so there is little evaporation once watered. I can't wait to see how this works out with my 4 tomato plants
