There are ways you can save seeds for a few months at a time. I would pop about 10-20 of them, isolate the males from females and then start growing them up in veg. Whichever ones are doing the best after 6-8 nodes, clone from those (forget the rest if you'd like). Put the originals into flowering and see how they do. Label which Clone coincides with which mother you flowered. Choose to stick with the plant(s) that did the best during flowering in your environment. This will be your genetics. From there use the clone from the flowering mother you want and have her become the new momma. Clone off of her anytime you need a new run. Keep her under a low T-5 (as you dont want her to out grow your veg set-up while flowering new clones from her. Every year or two repeat the selection process from the new momma plant and then you will have your genetics and your phenotype to use.
