> The energy required to photosynthesize will never be more economical from artificial lighting than the sun What about capturing and redirecting natural light, to replace or supplement the grow lights? I've seen "light well" systems that direct natural light around the building using mirrors and tubes (e.g. in office buildings to decrease lighting costs and combat seasonal affective disorder), so this seems like a natural extension of that concept.
