But yes, any veggies shes growing would not be vegan, because not keeping animals as slaves is an important part of veganism. I do believe you would find people who describe themselves as "vegan" that would be ok with this (like vegans that eat honey), but I believe it would not count as vegan under a strict vegan philosophy.
Source: I once subscribed to r/vegan as an observer.
I'll never understand moral vegan absolutists. There are so many non-dietary ways we cause direct or indirect harm to animals. I understand those who are vegan for dietary or environmental reasons, but moral veganism? I don't get it.
