For a newcomer to natural farming such as Lin, it will take at least eight years of gathering successive generations of seeds from the F1 (hybridized) plants grown in the first season before the genes can strengthen and learn to "survive independently in nature."
對林義隆這種新手農民來說，要想從嬌生慣養的「F1」種子，採集到具備可在大自然裡獨立求生存、基因穩定的種子，至少需 8 年時間。
