the way i see it, if you know you'll spend 1200 bucks for weed this year, then yes it's worth it. plus 1200 of the same quality weed you could grow would only get you like 3-4 zips, you could get that off one plant. I don't think you could ever spend too much on growing, and if you do, you can easily make it back ten fold with all the extra bud you could never get to smoking lol. go for it man, the most you can afford!
