Discover a simple and efficient method to cultivate potatoes right on your patio. These robust potato growing bags, available in black and grey, have an 8-liter capacity and are reusable. They conveniently fold flat for winter storage, requiring minimal space. The dark coloration of the bags shields developing potato tubers from light, ensuring healthy and flavorful harvests. Additionally, the bags absorb heat, providing a swift start to your potato growth in the spring. After successful technical trials, we recommend planting a single tuber in each 8-liter bag, resulting in an impressive 186% increase in yield. This noteworthy finding was independently confirmed in the March 2016 edition of Which? Gardening, where their trials team observed the same remarkable boost in yield. The dimensions of these bags are 8" x 11".
