Inflatable habitats are certainly a thing[1] and there'll be one attached to the side of the ISS soon[2]. However you need a bunch of layers of touch material to make a spaceworthy container that won't get punctured by a meteorite and that means light doesn't get let in so you need to light them. Shifting the spectrum of the light to something that chlorophyll absorbs best might make up for the solar panel to LED inefficiency somewhat.
