Irrigation Grids

The pvc grid idea was found on DavesGarden. It provides accurate watering when coupled with a automated sprinkler and provides great visuals for the planting squares.

Each 4x4 grid needs the following.

• 18 pvc lengths measuring 10-3/4”
• 6 pvc lengths measuring 9-1/4”
• 2 pvc lengths measuring 2-1/2”
• 9 cross connectors
• 2 elbows 90°
• 1 PVC Reducer Male Adapter 3/4” MNPT x 1/2” Slip
• 2 Male Slip Adapter 1/2” x 1/2”
• 2 - 1/2” Threaded cap
• 9 Slip on PVC caps

I used 1/2” schedule 40 PVC for the project and it worked will with my 3/4” water hose (note: this is why there is a 3/4” to 1/2” reducer)
