@Twofoot It is better to use auto pollen on a photo bud. It is up to you if you want to use Fem pollen or not. If you are making Colloidal silver and reversing a female to get fem pollen then that is ok to do but you will have to make new CS each time you want to breed. You will usually not have any autos in the F1 offspring but you will see about 25% autos in the F2 generation. The only reason to backcross would be either to get more desired traits from one of the two parents or if for some reason you do not get any autos in the F2 batch. I hope that helps, Good luck with your breeding, and let me know if you have any other questions.
