Hmmmm....I've grown a plethora of outdoor autos ranging from 12"-38" tall, thc levels from 16-22%, finish time between 56 and 106 days....sure beats waiting 4-5 months. What more do you want???? Quick finish time, easy to conceal, tasty smoke, great pain medicine.
The listed % of THC I think is rarely accurate.
They have some pluses outdoors, no question. But in general I had no luck with any of the strains I tried. La Diva was probably the best but I only had a few plants so I can't say for sure really how great it is. Blue Mammoth tasted pretty good and yielded ok/looked decent but there wasn't much buzz to be had. Really all the autos I've tried were like that. I don't understand the appeal some seem to have with them, but to each their own. I definitely wouldn't waste resources indoors with them unless they were on a windowsill or something.
