The container gardening methods as taught and demonstrated by Dr. Jacob Mittleider work just fine when the Grow-Box has a bottom.

Just build a box of any length - preferably 18" wide and 8" deep. Use painted or treated lumber, so it will last longer. Then nail 2 - 9"-width boards onto the bottom with a 1/4" gap between the two boards. Nail the bottoms to the sides for strength, and then drill many 1/4" holes along the bottom for drainage.

Free information on growing using this procedure is contained in the Gardening Techniques section at http://www.foodforeveryone.org.
