Alright breeders out there, as some of you savvy breeders already know this is where the “magic” happens! The F2 generation, when selected for with some actual skills, will usually deliver an array of phenotypes. Now, much like rolling two 6-sided dice, and the probabilities of the resulting rolls being most likely for a total of 7, with declining probabilities going to a 2 (snake eyes) or 12 (boxcars). This is essentially the same curve (bell curve) of possibilities and their guidelines for probability for phenotypes in the F2 generation. So keep that in mind…

I used 2 different females of the F1 Iron Cindy for this cross, as well as one very powerful, large yielding IC male F1s, and the male was a pure blood looking and acting Metal Haze, so he’s a winner huge, in my experience with these lines.

These Iron Cindy F2s will have severe flavors from Cat Pisy to overripe figs with a seriously true “dank” aspect to them. Resin production is a lock (homo) and all offspring will be deadly potent with major resin production; yields should distribute with 75% of the offspring (at least) having very large yields, with some way over the top large, I would seriously think. Legs (length of effect) should be long and very intense, very likely these will cause strong paranoia in those peeps that experience this effect from certain resin profiles. This is a very strong, very intense, almost pure sativa (probably 90%); so be warned! Count on these to all likely triple in size/height from the of flowering until harvest. Some will be less but many will very likely express this kind of sativa-ish stretch.

Germination rates are 90%+ (19 out of 20 for my test).

Cheers and enjoy, choose wisely from these F2s and you can bag yourself basically a one of a kind KILLER, with a ton of selected strong traits homo.

    I think the iron Cindy I have is Maybe a F1 ! I got these seeds in 2013 from Great Lakes Seed Company . I’ve been cloning off them sence then , I also gave clones of this to Diceman !
    One of my favorite

    I started with Iron Cindy a few years ago, with the F1’s and I loved the unique flavor and comfortable, spacey high. With the F2’s I noticed an increase in potency and a sharper, more zesty flavor. Iron Cindy is a perfect balance of sativa energy and a feeling of well being.
    I started 5 seeds and got 2 strong females, 1 is taller, stretches a bit with crystal covered flowers. The 2nd is shorter, sometimes 1/2 as tall as the first, it has denser flowers with lots of red hairs, both yield the same. My biggest problem with that is I can’t decide which one to keep! It’s been about 2 years now and I can’t bring myself to let go of ether.
    I always run between 4-8 strains at a time, but Iron Cindy has consistently taken up 40% of my space, for the last year and a half. It seems, around here, whatever your smoking, it’s always better if you have some Iron Cindy as well.
    I’ve grown out Fat Tuesday, Dark Dragon, Cap Peeler, and Black Forest. Iron Cindy is the one I’ll always run, just grabbed another 10 pack.

    Love this strain! Totally a high that feels from the forehead up. A great, incredibly potent sativa that is perfect for staying functional during the day. I joke with my wife that the high makes me want to do paperwork. Very motivating and functional yet super potent. I popped 6, got 4 females, 2 that were more Metal Haze that were tall and beefy and 2 that that stayed squat and fat. All responded great to topping. I kept the heavier yielding squat female. She’s super potent with almost no smell to her, definitely a valuable and stealthy pheno. A great strain that everyone seems to love. Much love to The Rev and KOS. You guys are amazing!
