I would like to install an irrigation system in my raised bed vegetable garden. The soil is like potting soil. There are 8 boxes, each 8 foot by 4 foot. I will use a 1/2 inch line between the boxes but Should I consider the 1/4 or 1/2 inch drip line? I am assuming that the drip irrigation would be the most flexible year to year. I will also need to run the system to each bed. I would like to have a shut off at each bed since not all bed have plants all year.
1/2 inch line - t valve - 1/2 inch line to next box
Shut off valve
1/2 or 1/4 Inch drip?
Does this illustration look correct?
Do you sell a water sensor so that system will not run if it has rained?
