I am sure you meant flower/veg boxes.If that be the case,this are available from many a hardware stores.Roto Tanks Kenya does manufacture them locally.
@Vinii,
Space need not be an issue.I have seen a dude doing Nduma next to his fence.The trick is simple.Dig a trench about 2 feet deep by 2 feet wide along the length of your backyard.Cover the trench with a polytherene paper including the closed ends.Tuck the paper,on the sides in a smaller trench and cover with soil.Fill the trench with good top soil mixed with chicken droppings or manure.Water the trench and introduce Nduma plants spaced at about 18 to 24 inches of one another.Feed the trench continously with kitchen waste water and watch your Ndumas flourish....Six months down the line,go and kiss your grocer good-bye.....hope this helps.
Nothing great was ever achieved without enthusiasm.
