If you aren't able to do 12/12, for whatever reason, stop growing marihuana.
No thank you. I would rather pay $120 over three months than $240 every two to three weeks. Just because you are growing photos doesn't mean you are growing the bomb, bro. I have grown Dinafem's White Widow, and for turned out abysmally awful. The autos that grew along side of it? Straight fire. Obviously the failure of the White Widow was due to my inexperience as a grower and I'm sure if I were to retry I could yield some frosty yum-yums, but in this instance autos yielded more and better smoke than a photo. Autos aren't what they were 5 years ago. Now-a-days they are a legimate, respectable variety of cannabis! So don't bash on people for choosing, or especially being forced, to grow autos.
Edit:
Furthermore, the ruderalis variety of cannabis is never sold by a seed bank. I can guarantee you that if you look at any breeder who offers Autos their genes will be "ghost og x (auto blueberry x auto big kush) for auto boo-berry kush" (that is a fake strain). So you see? To compare something that dilute full blooded ruderalis is a little silly. That's like using an msds sheet for concentrated acetic acid to safely handle vinegar.
Edit #2:
Even further, not everyone has access to the absolute flamest of the flame. If someone wants to follow an easy path to some decently dank and avoid their local, overpriced, under flushed, schwag; more power to you.
And if your trim is more potent than the main cola of an auto then you need to breed out that plant since apparently the sugar leaf is chock full of terpenes and flavonoids. Terpenes, for me anyway, is a huge part of smoking. I get way higher with bud that actually smells like something. I've smoked plenty of heaping trim bowls in my day, and let me tell you that I have gotten a better buzz off of Dog Shit OG.
Edit #3: The Final Chapter
Just wanted to show off my two autos; Heavyweight's Wipeout Express. They are so lush and full that they bulge out of my cabinet and I had to modify the back to allow my DWC res to sit further back. My modification causes a light leak so I'm happy I don't have two beautiful photos going!
