It's not legal to sell seeds in the U S. Go with known breeders who have been doing autos for awhile watch out for pollen slingers making outrages claims. I just " harvested " 3 autos I got for free from a seed co and there may be a half ounce total. If you don't want a tall plant top and train them to grow short and wide.............you'll get more and much better smoke.
