Tall fences, keeping them low profile, not telling anyone and if possible a greenhouse with many differetn plants around it to camoflage and smelling plants around it, ie peppermints lemon grass etc
Strains that aren't too pungent are also a great option, there are a lot out there. Also incorporating other plants around it or putting it in a location where it does not stand out. Location is key.
I Live in a free state, Massachusetts but that will not stop (fill in the blank) from taking your shit. I lost a couple to mold, but successfully harvested nine, two and a half foot tall-40 grams dried of flower each. I controlled height, kept them mobile, stashed them around the garden, near tomato’s, Russian Lavender, short fence, side of the deck, etc. I moved all of the girls to one spot each night that was dark, and secure. Lastly, defoliate, and manage smell by selecting a fruity flavor. Wouldn’t want to try to be stealthy with a skunk or diesel outdoors cause they are hard enough to conceal indoors. Don’t sleep on pest control, cause they will eat, kill, and slow your girls before you can blink. This is the problem with stashing them around the garden. Take your time and be deliberate with your actions. Good luck!
