I really have to disagree with most of these cats. Texas cops are a very different breed of cop. If you're not a prick about it, you can get away with almost anything.
I had an indoor grow in SA with a cop as my downstairs neighbor. He wasn't a half-wit, he knew what was up. If there was anything tipping him off, I still have the impression that he would told me to fix it rather than reporting it and getting me busted.
My friend had 8 large-ish plants in his backyard in Austin, and 2 cops wandered into his backyard while he was back there. One of them said, 'yep'. Then another one said, 'those need to go'. My buddy gave him a 'yessir', then they left.
The court system is the same personality. If you're an otherwise responsible citizen and don't have a gajillion plants, you'll get the minimum. If you don't have a record, the minimum is like 6 months probation for a pound or less. That's dried bud, as well. If they pull your plants, they dry them out, cut the bud sites and weigh those.
This is obviously going to be a bit different depending on the locality, but that's the south for you. The Nazis are going to be in the Dallas/Fort Worth area and any county on the border, especially Corpus. A lot of that is supposedly large gang-funded operations, as well. Anywhere else, you should be fine. Just don't be stupid, and don't be a prick.
