Ensuring that the food we eat is locally and sustainably grown is not always easy, especially in cities where crop-growing space is at a premium. Firms like Freight Farms and Cropbox, however, have a solution to this problem. They offer shipping containers that are kitted out as self-contained farms.
We've already seen the humble shipping container reappropriated for all sorts of different uses, including as part of an inner city farm concept. Freight Farms and Cropbox actually deliver that concept, albeit more practically and one container at a time.
The containers offered by both companies feature hydroponic technology, which employs a mineral-based solution in which to grow crops rather than soil. This means that the quality of the produce is not affected by prevailing weather conditions and that the conditions can be precisely tailored.
According to Cropbox, such systems use up to 90 percent less water than traditional growing methods. Both firms offer LED lighting in their containers too, which also compares favorably to other lighting methods. Overall, Freight Farms says each one of its containers takes 30,000 kWh of electricity annually to run.
