Just so you guys know, to stay out of the dark, there are a lot of "alien" beans going around. What you want to look for, is a parent that's either AlienDawg, Alien Tech, or Alien Tahoe. These are derived from Obsol33t's original Alien Tech which is a really, really fat classic land-race Pakistani/Afghan. Once hybridized it usually keeps it's massive colas, and takes on the frostiness of what the other parent is. There's a lot of hype, and a fake Alien parent of DNA genetics called Martian Mean Green. I really wish DNA genetics would leave the game out of shame already, what a bullshit company. That's another story. But you need to be aware of this. Martian Mean Green sucks and is just a mediocre OG basically.
Everything I've got to throw massive yields under COBs has been an alien family Afghan. The quality is incredible, the Alien Blue is a great example. I've never seen a more characteristic afghan in build. I just took an elbow to my guy, he cracked the bag, "Blueberry muffins dude". I didn't even tell fool it was blueberry. Always a good feeling.
So, if you want yields guys, I'm giving you a good direction to go in, as far as selecting your plants. Cookie strains do really really well under these setups too, make sure to keep them partially defoliated though. Alien all the way, I know it's one of those hype dragons you hear about all the time, but there's some truth in the fiction. Get the real alien though, and fuck DNA genetics. $100 10 drop vials of terps? Are you kidding me? I can buy a gallon of d-limonene for $15. Fuck those charlatans. Fuck Crockett gear, it's all shit, don't take my word for it, see what Medicropper has to say. Fuck Kosher anything, fuck the tangie (my mom bred the skunk they used, nothing personal), and fuck all these new "terp strains" that they've managed to engineer somehow in two generations. Fuck DNA and their lying, pilfering, anti-intellectual skulduggery, stop paying people to positively review your gear and step your fucking game up.
