A self-contained and easy-to-use cultivation unit for amateurs is herein proposed. The unit includes a sterile boundary isolating the cultivation unit from external contaminants, a cultivation chamber (10), a water inlet (50) configured to feed water into the cultivation chamber (10), and an air inlet (60) configured to feed air into the cultivation chamber (10). A first auxiliary chamber (20) is connected to the cultivation chamber (10) via a passageway (22), which may be manipulated from a closed state to an open state so as to introduce a substance contained in the cultivation chamber (10) and a substance contained in the first auxiliary chamber (20) to each other.
