ELON Musk's Space X will be sending cannabis to the astronauts on the International Space Station (ISS).

The space dwellers can expect their delivery to be on a Space X Dragon capsule, which is scheduled to make its next trip in March 2020.

Musk himself may be the man behind Space X but he's not the brains behind these weed plans.

It's actually agri-tech company Front Range Biosciences.

The firm recently announced its intentions to send plant cultures of hemp, the legal cannabis strain with low levels of the THC compound, to space.

Once there, the cultures are intended to remain in an ISS incubator for 30 days.

During the 30 day period, the hemp will be monitored remotely from the University of Colorado, Boulder by BioServe Space Technologies.

The cannabis cultures will then be sent home to Earth.

Once home, Front Range Biosciences will be observing what effect, if any, space radiation and micro-gravity has had on the gene expression of hemp.
