^ good comments imo. If you're using good soil with a buffer like lime you should be ok. If you have hard water, go buy water.
ONLY adjust PH if you're monitoring your PPM levels. Over the counter PH adjusters can quickly jack you're ppm's up. Especially if your water is already high in parts per million. I worried about ph so much in the past and had a lot of problems. Bought a ppm meter and stopped adjusting PH. All is well
From my experience you don't need to PH your water outdoor, but then Italian soil is totally different than yours. If your water goes over 7,5, and your soil doesn't have a healthy biota and is prone to water logging, then some adjusting might be necessary.
