That's the answer to your question ....
I would love to get my hands on some ditchweed seed.
Everyone would love that but as good as nobody can... it seems easier to grow +25% THC hybrids under 10'000 W in your garage, discard the coco coir at your McDo's, dry the plants in your shack, make BHO out of it in your backyard, and sell the shatter on your street than to go for a hike through nature collecting a handful of ditch weed seeds... but then again, I'm not American...
