Yes, thanks for the info Boris. Our climate here is unpredictable in terms of temperature. Sometimes it can go without rain for days. Sometimes it will rain on one half of the day, say the afternoon, and sunny the next morning, and the cycle repeats for a week or two. When I was studying in Melbourne I also used a conductivity meter and used my aunt's plants as testers, which are actually Sarrs. They were responding well to the water quality too.
