Maker the Caledonian Tree Company decided to make the propagation product available to amateur gardeners because of the upsurge of interest in grow-your-own.
Air-Pots are made from recycled HDPE bottle waste, near Edinburgh. Representative Suzie Single said: "Not only is it a good news story for plants, but an unusual story of British manufacturing success. What's more, the Air-Pot has been designed by horticulturists for horticulturists and is exported across the EU and the US."
She said the pots work well with "potatoes, tomatoes, cucumbers and the whole spectrum of fruit and vegetables", avoiding "wet feet".
Royal Botanic Gardens, Kew, Royal Botanic Garden Edinburgh, Bedgebury Pinetum and Westonbirt Arboretum use Air-Pots to propagate seeds from all over the world and to grow without root circling.
