I live here in Houston, and as I said above, I almost completely stick to purely Sativa. You can definitely get your hands of premium grade stuff down here, you just have to be willing to pay a little bit more since I believe it's not locally grown. And $20 a gram is about the standard, regardless of strain. Unless you're getting into the 30%+ stuff, which will run you anywhere from $25 - $40 a gram. But I don't mess with strains that potent, you get to a certain point where it'll just tranquilize you
@ShAdY, I believe what you have is Strawberry Cough. You can do a google image search to confirm. We get a lot of it around this time of the year, and you can expect to see it around until Winter. But yes, it is Indica dominant, so I recommend it for playing video games or going to bed. Not a day-time strain.
edit: also, try to buy as much as you can at a time, since most dealers will give you a discount for buying in bulk. For instance my guy will only charge me $15 a gram if I buy an ounce. You get the idea.
