My thought would be to grow something really tall that doesn’t mimic MJ on the outer area you want that people initially see, a layer of a mimic plant on the inner part of those, and put the good stuff in the back or middle depending on layout. (As long as it will still get decent light)
I feel like mimic plants in plain view lead to people being curious and checking it out looking for goodies haha.
dealing with this myself this year. i will be using tall sunflowers this year as a sort of living fence. way easier and cheaper than building a fence so that my plants cannot be seen between my house and the de attached garage as people drive buy. i want to move them out further from the garage this year for more hours of sunlight but without some sort of barrier people will see them because i am growing large strains. so for me sunflowers it is. budget friendly to boot.
