    Lines that have been selfed or sibling crossed for many generations become very uniform, but they can also lose vigour, with slower growth and smaller yields than a fresh cross. That is why a lot of the best performing indica hybrids are F1s between two unrelated stable parents. The trade off between uniformity and hybrid vigour, and how to read a breeder's description for signs of an overworked line, is laid out on https://kushindicaseeds.com in a genetics explainer. Uniform is not the same as strong.
