Place a cap on the end of two 1-inch PVC pipes that are 11 inches long. Hit each cap with a rubber mallet to secure it in place.
Position a T-elbow on the top of the two 11-inch long PVC pipes. Insert a 1-inch section of PVC pipe that is 11 inches long into each T-elbow.
Place a 90-degree elbow on each of the 1-inch PVC sections that are 11 inches in length at the top. Insert a 1-inch section of PVC that is 24 inches in length between the elbows to make the front end of the piece. This is the front support. Repeat this process to create a rear support with the 10-inch long PVC pieces to create an angle for the nutrient solution to drain.
Connect the front and back supports with two 24-inch long PVC pipes inserted into the middle of the T-elbows.
Drill 1-1/2 inch holes into the sides of three 36-inch long PVC pipes every 8 inches. Clean out the inside of the pipes.
Place a cross elbow at each end of the drilled 36-inch PVC pipes.
Insert a 4-inch section of PVC into the sides of the cross elbow. Attach one 90-degree elbow on each open end that extends from the cross elbow.
Attach the last two 36-inch long drilled PVC pipes to the 90-degree elbows that come off of the cross elbows. Place end caps on all three 36-inch long drilled sections.
Insert a 3-inch section of pipe into the last remaining hole in the cross elbow. Attach a 3-inch section of drainpipe. Place a bucket under the drainpipe.
