Let’s explore the Wick System, one of the simplest and most low-maintenance hydroponic setups.”

“In a wick system, a tray with plants sits on top of a nutrient solution reservoir. Wicks made of rope, string, or felt stretch from the reservoir to the growing tray, using capillary action to pull up water and nutrients to the roots.”

“This setup is **passive** – no pumps, no electricity needed! The wicks do the work, absorbing water and nutrients to keep plants hydrated.”

“To work well, wick systems need a porous growing medium like coco coir, perlite, or vermiculite. These materials are perfect because they’re highly absorbent and pH neutral, allowing easy nutrient transfer.”

“Aeration isn’t necessary, but some growers add an air stone to increase oxygen levels in the reservoir.”
