EP,
I know exactly how you feel. There's no way i could go back to smoking schwag. Funny how the stuff i used to think was pretty good tastes like dirt to me now.
The plus side to growing your own is that your quality is just going to get better. My first set of plants produced decent potency bud, but nothing compared to what I'm getting now that I have several grows behind me. I'd be willing to set my blueberry against the blueberry you can get at the dispensary any day in terms of the high and taste, though I'll admit I don't get quite as tight of buds (I use 600w lights, most of them use 1000w) And the yields are far better once you've had a chance to really learn the strain and dial in all the variables in your grow.
Hey Riddle, I've proven to my own satisfaction that you can take a strain far past the "limits" of it's genetics with enough veg time and a good environment. Or at least you can with blueberry. My blueberries are Indica dominants that are supposed to top out around 4- 4.5 ft tall, but I have several in flowering that have passed the 6 foot mark currently, and two that are still in vegging that are getting close. Veg time has averaged 8-9 weeks starting from 5 inch clones, with a single fimming at week 4 of veg. I have been giving them very minimal nutes during veg and have also discovered that a 5 gallon pot full of happy frog can go 7-8 weeks and produce a 4ft plant with a single dose of nutes at the beginning of week 5 without the plants showing any signs of nute deficiency at all. They might have grown faster with more nutes, but considering how big they are without them I'm glad I did it the way I did.
