Farming in small spaces

Eco & Sustainability
Gardening in bottle caps is a fun concept that’s well-suited to urban settings, but consumers interested in growing more substantial crops might be better off with Whirligro instead. Targeting those with limited growing space, Whirligro uses spiral-shaped tubes to elevate food crops off the ground and enable greater production. Designed primarily for fast-growing leaf crops,Whirligro uses durable, transportable growing tubes that can each hold three plants. Each Whirligro unit, in turn, holds 10 tubes spiraling around a central post, offering the combined ability to grow 30 plants in an area smaller than one meter by one meter. Plants grow through holes in the plastic tubing, reducing any weeding requirements to a bare minimum; because the plants are off the ground, meanwhile, pests tend not to be a problem, the device’s Scottish maker says. Watering can be done by hand or with a small drip irrigation system. Pricing for the Whirligro ranges from GBP 55 to GBP 140, depending on size.
