More than 200 million hemp plants are being grown near Market Harborough as part of a new research project.

It is the largest UK study of its kind, looking into the benefits and sustainability of Hemp - which is a type of cannabis plant.

This year's crop, which is able to absorb CO2 much quicker than other plants, can absorb the harmful gas in its 120 day growth cycle - a forest would take 25 years to absorb the same amount.
