Did you find the different versions of Gorilla Glue (presumably from different breeders) had a 'similarity' to them, because all are supposedly sharing common genetics, or were some of those different versions totally different and seemingly not related? I am currently growing out a Gorilla Glue Auto, both the Gorilla and growing an Auto are new experiences.100% with you on that one buddy. One of the benefits of 420. I would love to generate a great strain to seed and share . My hope atm is to crack one of the accidental crossed strains I have from a previous grow. I am a big Gorilla Glue fan and have a few diff versions of it under my belt and slowly building a collection of breeders seeds too. I know its business to them but it kills me that a seed can cost so much when you harvest thousands from a single decent branch , never mind a whole plant. !!! Self sufficient growing is an aim for me and sharing the load is always a way forward if only we didnt get chastised for it due to sponsors needs.
I totally share your thoughts on pollinating selective branches to harvest your own seeds. I'm curious as to whether your own seeds have proven to be similar in potency/approval as the breeder seeds you grow. I would assume as long as you start from decent quality it should carry on in your own seeds.
