It's not as hard as it appears, time reading and research is the best way. Never listen to every post everyone has different ways. Personally I would recommend a male of one and a fem in the more potent strain. Seems to work well. Take a bag tighten Round a branch, shake well on the male so you know you've shaken enough to cross pollinate. Take bag of carefully and put it over a main cola. Tie it on shake well and leave it a while. Take it off after 12 hours and continue to flower. After about 2 weeks you should see sighns of what looks like a hermie plant, once they produce the seeds there will be dark ones with 3 edges =female seed and light greener looking ones with two edges, these are male. Use your seeds leave a female to go to seed to continue your strain. The first seeds are generally the weakest but still work, as you get into second gen seeds they get stronger and 3rd gen will be far stronger then the first two lots. These are second gen and have already hit stability which is a very good sign. The more you work at it the easier it becomes. Just make sure you do it in a different environment to your grow as you don't want a crop with a load of seeds. I waited until I had pulled my yield then cross pollinated first time, second just let a fem go a bit longer so produced seeds. Will be doing same again this time for my third gen seeds. I like to be different and wanted my own strain. Something I knew would yield well and have potency too. This cross has proved it's self massively and I am quite proud of the results even though at times I have been a little under yielded in the first seeds the second have by far improved massively. Can't wait for the next gen, will be my own mix that personally I love. The strength is absolutely awesome and this time I will be shocked if my buds ain't a foot long on tops. They have done so well I don't want to buy anymore seeds, I'd rather stick to my own as I know what they are capable of
