Well, I intend to grow entirely indoors..and have yet to plant all the new hot seeds. Am I insane? Maybe.
But, if you create and maintain your artificial envrioment..who knows?
I live 3 floors above any real ground..and I have no doubt that I can grow whatever I choose.
I have 80w of Ecolux lights plus the real sun that is in a s/w window, and planning.
Best wishes.
