San Bernardino Mountains, California
It appears the police may be working with people more now than they were in the past. Tons of growers with many more on the way. It used to be hard to get materials, seeds, and clones that were guaranteed authintic strains. Plenty of stores now close by. Ace Hardware in the mountains carries products like Foxfarm, etc.
Had a sheriff come visit me the day after my last divorce about 2 years ago... He said there was a tip of smell... I live on a acre of land and have NEVER used any kind of carbon filter. When flowering it smells like heaven around my place. The cop was totally cool. He asked for my growers permit (state recommend). I told him I didn't have one. He said, "No problem." I did have a docters medical recommendation which is all that was required at that time. How many plants he wanted to know? Well, ummmmmm... He said, "Your good up to 99." Actually, you can only have 6 flowering/6 vegging Per each person you are growing for that has a valid medical recommendation and you have that documentation available.
When we went under the house to check space out he just looked at them and said, "Beautiful plants!" He left shortly afterward...
Had no problems ever in last 15 or so years of growing.... Going great and now expanding another space...
