Thank you so much Shiva - this is reassuring!
Re water, I have an irrigation line for my plants/hedges. Re the smell - I wonder! My garden is 25m wide, backing onto the green, so only side neighbors, and nearest is about 7-8 meters away behind the hedge and fence. As this is my first year, I have no idea how strong the smell gets, and whether there are less smelly genetics for that purpose. Is it as bad as someone smoking a joint at all times? I can definitely tell my neighbors that I smoke cannabis for medical reasons, as they know that I have PTST and struggle with sleep. But if the smell if overwhelming and exotic, It won't work. Behind our wire fence, so about 10m away, people stroll every eve and morning and they will surely notice.
