Splitting Garden Beds into 2 Zones

2 Zones - 16 Beds

This is an example of how to zone off beds. 

Each bed uses 4 rows of DET Tubing for full coverage of the 4' wide beds. Calculating the water usage of the beds helps to separate the beds into zones to ensure that enough water flow is available to water the different clusters of beds. One zone is about 390 GPH and the other is about 280 GPH. Using a 3/4" supply line will ensure that there is enough water available for these zones. 3/4" can handle upwards of 400 GPH so both zones are satisfied. If you chose to use 1/2" tubing you'd need to split this system into 4 zones since both current zones exceed the maxmimum water capacity of 1/2" tubing.
