Step 1: Use a PVC pipe of 3 inch { 76mm } diameter and 1 metre length. You can plant 6 to 7 plants in a metre long pipe. You can make stacks of 4_5 pieces.
Step 2: You will also need two end caps of close both ends of the pipe. Make holes at equal intervals in the PVC pipe using a saw drill. You must be careful to ensure that the size and distance of the holes accommodate the net pot and keep equal space between the plants.
Step 3: You can get the help of an expert{ matal fabricator or carpenter } to drill a hold in the PVC pipe. Place the end caps at both ends of the pipe. Drill water inlet and outlet holes at the side of the end caps. You will need to seal these holes will a silicone glue gun after placing the water pipe.
Step 4: Make a structure using wooden or bamboo sticks or a metal rack to place the PVC pipe vertically.
Step 5: You can use a water bucket or a tub as a water reservoir. Add a water pump to the water inlet while connecting all the outlets to the NFT beds. You can attach a simple on- off timer for controlling water flow. An on off timer is a device that automatically turns on or off an electrical appliance at pre determined times.
