A wicking irrigation system is an efficient and sustainable way to water plants. It delivers water to the plant roots directly from a reservoir, reducing water consumption and time needed for refilling containers.
The essential components of a wicking system include:
Container with the plant
It houses the plant and growing medium. An upcycling opportunity here could be using discarded buckets, large food containers, or old pots instead of purchasing new ones.
Reservoir
The reservoir is where the nutrient solution is stored. It could be an upcycled plastic container, a used storage bin, or even an old aquarium.
Hydroponic Growing Media
The growing media in a wick system is an inert substance that anchors plant roots. Hydroton (expanded clay pebbles), perlite, and coco coir chips are often used. While these substances aren't typically upcycled, compost can serve as a nutrient-rich medium made from organic kitchen waste.
Wicking Material
The wick is a critical component that draws the nutrient solution from the reservoir to the plant roots. Old cotton clothing, nylon ropes, or even strips of used towels can serve as wicking materials.
Nutrient Solution
This is the water mixed with essential nutrients that the plants need to grow. While you can't upcycle nutrients, it's possible to create homemade nutrient solutions using compost tea made from organic waste.
Pumps, electricity, or aerators
While typically not required for a simple wick system, some advanced systems might use these for better nutrient circulation or oxygenation. Solar-powered pumps could be an eco-friendly choice if this is desired.
Monitoring and maintenance are vital for the successful operation of a wicking system. Regular checks ensure the nutrient solution is being adequately absorbed and prevents issues like salt buildup. Incorporating upcycled materials into the system not only gives a second life to items that would otherwise be waste but also aligns with the ethos of sustainable, environmentally-friendly gardening.
