Subbed, thanks for letting us in and sharing this nice log!
Innovative little spot, I did something like that once back when I first started smoking but I had a hard time just keeping a 5X5 area clear the blackberry's kept trying to take my clearing back... Although I ended up having the plot "done in" after a MAJOR infestation of one of my least favorite and most common bugs in my terrain. Ear wig's... ewwwww so creepy and they love to eat my plants... buggers. Although that was one of my first times ever growing, didn't know how much work I was setting myself up for... But wow dude you have done well maintaining that plot thumbs up and a +rep to you brother. (I think I remembered to rep... so tired... hope I did.)
Curious question, do you have your permit's in order? My next property I may consider something like this just to keep ripper's out... But I ask because you mentioned the grow is close to home, and the cultivation pattern seems relatively visible from the air, but if ones permit's are in order the point is moot. Although if I had an inspection I have a feeling the ol' PO may be ticked having to either use a mirror or go crawling to check to make sure I am within my limit's. Still a tempting thought though, such a nice spot if it can be maintained. Oh and if ones permit's were not in order having such a small escape hole would freak me out, when guerrilla growing I would prefer to know of several ways out and quick.
Thanks again for the tour and great log!
