Under a yellow tarpaulin stretched over an arched metal frame, Siraj Bechiya and his partner inspect their hydroponically-grown lettuce, pioneers of the method in mostly-desert Libya where conventional agriculture struggles.

Zip ties, punctured plastic cups as pots and PVC tubing bought in DIY shops hold the precious crops at "Green Paradise" - so dubbed by the two young Libyan entrepreneurs spearheading the project.

Their hope is to demystify hydroponic farming, which "guarantees a good yield in small spaces", uses little water and doesn't need pesticides, 20-year-old Bechiya told AFP.

Soilless farming has gained ground in many countries but is still in its infancy in Libya. But in a country whose territory is 90 percent arid desert, the method could offer a path toward more food self-sufficiency, Bechiya believes.
