"The supermoon is a made-up term," said James Lattis, an astronomer at the University of Wisconsin-Madison. "It's not an astronomical term, there's no technical definition of it." Supermoon was actually coined by an astrologer in the 1970s, not by a scientist. The term has come to loosely mean a full moon that is at perigee, or when the moon is at its closest position to Earth along its orbit.

Crops are grown indoors, under artificial conditions of light and temperature. It aims at higher productivity in smaller spaces. It uses soil-less methods such as hydroponics, aquaponics and aeroponics.

Vertical farming uses significantly less water and pesticides than traditional agricultural methods. Being indoors, the crops aren't subject to seasons and hence give high productivity year-round. Lettuces, tomatoes and green crops can be produced through this practice.
