No its not about Paranoia, its about having the most expensive plant in the world on your property..

My shed has motion sensors in all corners, and I have a back to base alarm with more motion sensors, on the whole house so if someone does break in, the security comes running not the cops.... The security company is one suburb over...lol....
Its not paranoia, its just protecting your investment, not only the cash value, but the equipment replacement costs and the time you've put into a grow. Ive been ripped a week before harvesting about 14 years ago, its the best lesson I've could have ever learnt... Just a random robbery, no one knew I was growing, it was my second harvest EVER....
