Does the greenhouse effect refer to growing crops indoor?

No the greenhouse effect only effects the ozone which protects us (humans) from harmful UV rays (ultra violet rays) but the crops indoors are still getting the same amount of sun rays and be able to grow. Of course we would burn to death becuase the ozone layer is gone.

No it does not the green house effect refers to gasses in the atmosphere trap the heat inside the atmosphere after the suns rays come through making life possible on earth however it also keeps some of the rays out keeping us from getting to hot
