That is just one of those unknowns. However, my initial harvests were quite low, so as my neighbours have stayed the same it amounted to testing the waters. So now I guess it means it is either under the radar, maybe they don't smell it or if they do it isn't apparent what it is, or maybe it isn't an issue for them. I'd like to think that a lot of civilised people would view it as little different from any herb or vegetable grown in the garden, and if it helps people's wellbeing who choose it then all good.
But of course it is still a concern, last year I got 23oz from 2 photos and an auto, it was more than I had expected and surprisingly it all seemed to go unnoticed, so this year I did the same feeling a little more 'comfortable'. But we only get one life!
