What’s the 411 on 420 Pheno Selection? - by Drew Dorr, Pure Michigan Genetics

     In the last addition we talked about the real basics on pheno selection, or creating your own strain. We discussed how to pass along CBD-THC potential, the chances of variable, the science behind crossing, and so on, but none at length.

So what are the basics then? Where do we start?

     That’s a great question! Essentially, the process begins with YOUR imagination! What we want to have the final product be is what we need to start with, so what we will do is break down the steps with you to make it not only interesting, but easy to follow.

     The most important things in stabilization are to make sure you keep not only a 100% healthy garden to the best of your ability, and also having the mother and father plants of the genetics you are using to cross and stabilize. Keeping these plants around is important because you will never be able to select the pheno types you desire without having these plants to increase the likelihood of that pheno.

     If you are trying to breed a short, stout plant, you wouldn’t want to use a strain that is known for its tall, stretchy stalks. This is the basic structure we need to think about when selecting plants. Typically with seeds, and regular seeds specifically, you have a wide variety of pheno variances.  If I pop 100 seeds of the same strain, 1 out of those 100 might differ drastically from the rest. This is why it is important to pop a bunch of different seeds when trying to select a pheno and to not settle with the first female you get.
     When you do find that amazing Pheno, cross it with the original male used in the cross to make this specific seed. When stabilizing, a good rule of thumb to follow is this: “What I want in the end is what I want to start with”. Keeping these around till the end makes it easier to stabilize and makes the end result of stabilization a strong one.

     I will also break down one of our genetics over the next few editions, focusing specifically on a Poison Kush F2. This will help explain a lot about regular seeds, males, females, feminized seeds, and so on. I will also show you some tricks and other steps along the way, and provide scientific structural information in order to help break down the process to ensure that your garden is safe for seed growing and harvesting.

     When I set out to stabilize Poison Kush, I followed this exact procedure, and I still have my original Durban Poison and Kush plants to this day! What sort of Kush, you ask? Stay tuned for next the edition to find out!

     Have any questions about genetics? What about grow questions? Deficiency concerns? The magazine is always looking for high resolution pictures, and so are we! Send us your grow pics and questions “why is my plant turning yellow?” Stuff like that! Might just make it into the magazine!
