Glasgow-based POTR’s new “Helix” pot expands from a 0.25-litre container to a two-litre planter as plants grow, allowing users to avoid repeated repotting while incorporating a self-watering reservoir.

The product smashed its £4,000 Kickstarter funding target in just 24 minutes and has since attracted more than £24,000 in pledges from over 300 backers.

Designed by husband-and-wife team Andrew Flynn and Eilidh Cunningham, the pot took almost two years and more than 1,100 prototypes to develop. Made from recycled polypropylene, it ships flat to reduce packaging and transport emissions, with the first products expected to be delivered in September.
