This is just a guess, but you're in a 3 bed, 2 bath right now? Maybe try a 3rd tent in that location and try to run them 3 weeks apart?
Would add 1/3 to the bottom line, with little additional ongoing overhead.
Don't get me wrong, I'm along for the ride and it's a fabulous show, just thinking that while you're fine tuning, maybe making more use of available space would be more advantageous. I could see several benefits from just adding a 3rd tent. Would let you experience a heavier work load (increase of 50% over current), managing/timing 3 grows to keep them on track and spaced/timed as best possible, etc. While it would add to the electric/nute/water bill, at least that is small in the grand scheme of another property, which would bring things like more insurance, taxes (blah!), upkeep, maintenance, etc.
Of course some of that can be hired out, if so desired. If the yard isn't super big, $35-$45/wk to get the grass cut/trimmed can be money well spent in terms of time/energy saved. Now you don't want people nosing around, but those lawn companies aren't interested. They want to get on site, cut and trim, and get on to the next lawn. Of course that's assuming the site doesn't reek of that fine sticky icky going on inside.
Seriously though, I know we've discussed security, but outside of remote/video monitoring are simple home security systems. Ones you can install yourself (big plus there) with remote monitoring. You're legal, so that's a big relief there, which does open up options which are not available to a super secret grow.
At the very least, you can buy yard signs and window stickers for most well-known security companies. Combine that with a couple "dummy" cameras (they look real, and have "on" LED's to really sell their authenticity) and that may be a big enough deterrent to potential trouble makers. It's security by obscurity, but it makes it much less attractive to someone looking for an easy target, whether they know what is there or not. (And you certainly don't want someone looking for an easy target, knowing someone isn't there most of the time, and then finding out they hit the jackpot.)
Another option would be adding several 4x4 (or 5x5) tents. One of those lights would rock a space like that, you can get 4 plants in there for a SCROG, and can get creative with things for ventilation purposes. (Think a big main fan, that sucks air from multiple tents, etc.)
Sorry to derail the thread a bit, but your updates and creative ideas always spark my own!
