I want to run an automatic watering system with the dual purpose of watering my garden while watering a few plants on my walk way and hanging plants off the Pergola. My question is first is this possible, in my mind it seems straight forward, I was thinking of running 1/2" tubing across my Pergola and have drops with 1/4" tubing to the pots I want watered. This is where I'm not sure - I want to water some larger ground plants as well, should the 1/2" tubing going to the ground and run 1/4" with spray heads? put a sprinkler head at the end of a run out and water from above? and lastly I am concerned of water pressure and will the water be able to travel up 10ft and then be able to do what I want. Will I need pressure regulator? The total distance traveled for 1/2" line I am guessing to be about 40ft the hanging there are ~10 hanging plants 6 larger plants that are on the ground and they are in clusters of three and fairly close to the Pergola. Another wrench in close proximity I would like to run a drip line out to my very small garden. Should this be run separately ?
