If anyone wants a quick and easy crop to grow in a small space try radishes. These are grown in a small supermarket plastic produce tray about 12x9 inches and 6 inches deep.
Excellent idea Colin - how to get the most out of a small space - I wondered what to do with all those plastic trays - now I know. Good tip.
Love this tip Colin - one way to squeeze some extra space for growing. Pretty big tray though, the ones I throw out recycle are half that size; it would still work though, so thanks for the idea!
