Don't owe anyone favours, make them think they owe you, if someone finds out about your grow, and you owe them something, they might ask to get something for free, it doesn't work if you owe nothing.
Keep people that don't belong at your grow, out of your grow. I've been at the"farm" and had someone ride up on us, to give me a ride home. She didn't know that we were about 200M from 30 ganja plants, because I was right there at the street waiting.
Keep your job. I have a big outdoor grow right now, that I'm counting on to help with rent and other bills, I got waaaaaaaaaaaaaaaaay too complacent, feeling like in a little while I'm not gonna need this job anymore, I should cut back on my hours etc, and my boss canned me without warning (I'm thinking its cause my dude at the time came up to my job once to often, keep this shit and personal shit like your job far far apart) Now I'm racing around, trying to come up for rent for this month, trying to come up with a legit reason I don't have to move 7 miles down the road back into my parents house (they don't smoke anything, not even tobacco) by the end of the month! I did find a job, now its just a race to get my paycheck, I still don't care how many hours I get, I still "won't need the job" in a little while, BUT my boss doesn't need to know that, the boss only needs to know that I'm available whenever he/she needs me (which i hope isn't 8 days a week like my last job...) Also having a job means I don't pay ALL of my bills with cash, and I get to deposit money into my bank account every once in a while when I cash a paycheck
