That blue stuff really caught my eye! Is that a light trick, or does the plant really turn blue?
Its funny you mention a project of WW x SH. Do you mean Super Silver Haze? I have a small amount of SSH x WW seeds that CLS gifted me. Its been hard for me not to grow these out yet, so I can understand your desire to make it happen. Best of luck with your breeding project. Sounds tantalizingly fun.
And yes, it would be an F1 Hybrid in the initial cross. I believe you have the definition of a bx correct as well, but backcrossing aka cubing isn't the best method of breeding from what Ive learned in my time on these forums. There are many methods available so do some research before beginning your project and have a blast with it.
That is pretty wild! Coincidence at it's finest heh I've just been wanting to cross the two for years and now can finally get a start on a few crosses i'd like to do fairly soon Just a solo project though, I have some old 10yr old seeds of both strains I've been wanting to pop sometime soon and see if there's anything worth while. Much appreciated brotha, I will do some more reading for sure
