Bristol tech start-up firm pioneers growing salad indoors

A biotechnology firm is finding ways of growing a range of salad crops indoors.

The Bristol-based firm Lettus Grow suspends the roots of plants in a "nutrient-dense mist" rather than in water.

The company was awarded 100,000 euro (£89,000) on Thursday in the Postcode Lottery Green Challenge which awards cash to firms developing environmental business projects.
