Houston has always been this way. I asked my dad about it, (he moved here in 1970), and he thinks it's just that there is soooo much mexi brick to be had.
I've been growing for quite a while now, and hope to improve things in my own little way. My first two grows were with schwag seeds, and with 'home grown' TLC, they were a pretty damn good smoke. Far better than the squashed bricks.

Ya have to consider that many if not most of the schwag females have been pollenated, cutting thc levels by 2/3's or more, and that curing is almost non-existent....B
