Recirculating Hydroponics

Step 3 The pump and spray bar.

We'll be building the spray bar in place to make sure it's right. stack the two containers. cut a piece of 1/2 inch pvc to sit in the notches cut in the top container, leave a couple of inches over hang for fitting attachment. cut a second piece and add an elbow, stick it in the hole in the side of the bottom bucket and now just cut a piece of pvc that will join those two pieces together. Add the end cap to the top piece and screw in the plug.

Now drill a bunch of 1/8 inch holes into the pipe across the top bucket to create the spray bar. Split the end going into the bottom bucket with a hacksaw about 1.5 inches.

The pump is attached to the spray bar with a piece of clear vinyl tubing, fortuitously the vinyl pipe slipped right into the pvc, the split lets me cinch it tight with a zip tie.
