This listing is for 40 GroPockets, designed to fit on 4" S&D (sewer & drain) pipe. It also includes  a marking template and 4 basic irrigation heads. The pipe is not included. You may also want to order the stain or eyebolts which are separate listings. 

Includes:
40 GroPockets
4 Basic Irrigation Sets
1 Marking Template

How to
Use a standard 2" hole saw to drill holes in the pipe. Then use PVC cement to adhere the GroPockets to your pipe. This creates a watertight solvent weld.

How Many?
A 10 ft piece of pipe can be divided up into two 5ft towers or three 3ft towers. If you put only one plant per row either approach will hold 18 GroPockets. 

If you want to grow lettuce or something similar and you can space them out 2 plants per row followed by 1 plant per row, then 2 etc. You would need 28 GroPockets for this spacing for 5ft towers and 27 for 3ft towers. 

If you are growing strawberries or some other small plant and want to do 2 every row, then you would need 36 pockets for a single 10 ft piece of pipe.
