Wick hydroponic systems are one of the easiest setups, making them a favorite for beginners, and in classrooms. Plants sit in a tray filled with growing medium, directly above a reservoir. ‘Wicks’ or cords should have one end submerged in the nutrient solution, while the other end threads through holes in the bottom of the tray. The top end of the wicks go in the growing medium, within reach of plant roots. The wick absorbs nutrients, which travel up the length of the wick and into the tray. The growing medium absorbs some of this moisture, allowing plant roots to take in the nutrient solution.
Benefits of wick hydroponic systems include incredibly easy setup, and simple materials. In fact, there’s no electricity or moving parts required at all. Wick systems are incredibly beginner friendly, and low maintenance. However, because the wick doesn’t deliver a large amount of water to the plants, it’s best for smaller plants and those don’t need as much water to thrive.
