There are all sorts of uses gardeners find for PVC tubes including irrigation pipes, in wicking beds, worm farms, compost systems, rain gutter gardens and vertical tower planters. It’s understandable. PVC is cheap, widely available and an easy solution. It’s commonly used in landscaping, aquaponics, hydroponics, garden gloves and hoses too.
