If you need to water potted plants during a vacation, here’s a basic setup which worked for me.
You first need a timer to let it know when you want the water turned on and for how long.
I used the Orbit Timer – it’s the basic unit. It uses 2 AA batteries and worked well for my last vacation.
I’d suggest testing it ahead of time so that you get the amount of water you need for your plants.
You can see most of the pots I wanted to water, plus there are a few which are hidden that it reached also. I just moved all my pots to within range and everything was alive when I came back. You can use whatever sprinkler you have on hand.
Note – I let Mother Nature take care of my lawn and other plants, although I do water ahead of my vacation if needed.
