Introduction to Wick Hydroponics

Wick Hydroponic Systems represent a basic yet user-friendly approach to soil-less plant cultivation. Designed with simplicity, they suit beginners and those keen on grasping hydroponic basics. In these setups, plants receive water and nutrients through a passive wick mechanism, eliminating the need for intricate machinery. While easy to maintain and cost-effective, wick systems might be less efficient than more complex alternatives. They work best with fast-growing plants like lettuces and herbs that require moderate water.

The foundation of a Wick System lies in its simplicity, requiring only a reservoir, pot, growing medium, nutrient solution, and absorbent wicking material like cloth or rope. These systems operate through capillary action, a phenomenon seen in everyday instances, such as clothes wicking away sweat or paper towels soaking up spills. Similarly, plants utilize capillary action as their roots absorb moisture from the growing medium. This process occurs due to water’s adhesive nature, causing it to adhere to thin tubes or porous materials.

Elements of Wick Hydroponic Systems

Grow Tray: tray in a Wick System stands out for its departure from conventional hydro setups by not using net pots. Instead, the tray is filled with a growing medium and directly transplanted seedlings. Optimal growing media, such as vermiculite, perlite, or soilless mixes, harness capillary action effectively while preventing excessive drainage and maintaining a balance between moisture and aeration.

The Reservoir: Analogous to other systems, the reservoir stores nutrient-rich water underneath the grow tray, supplying plants with essential sustenance. Regular replenishment is necessary as nutrient potency diminishes with plant absorption.

The Aeration System: Typically consisting of an air stone and pump, the aeration system infuses oxygen into the water. Like its aquarium counterparts, the stone releases bubbles via an external air pump. Oxygenation of roots is vital for plant health, especially in Wick setups where roots remain consistently moist.

The Wicks: Connecting the reservoir to the grow tray, wicks utilize capillary action to deliver nutrients to the plant roots. While cotton ropes are simple, nylon ropes offer durability without mold concerns. The number of wicks, determined by system size and plant type, dictates nutrient transport efficiency.

Creating a Wick System: Effortless Hydroponic Setup

  1. Prepare Wicking Material: Cut six to eight sections of wicking cord, each measuring 15 to 20 inches long. Common choices include nylon or wool rope, braided polyurethane yarn, propylene strips, mop head strings, and strips from old clothes or blankets.
  2. Drill Wicking Holes: Drill holes at the bottom of the top tote (growing area tote) to match the diameter of the wicking cord. These holes enable capillary action and even moisture distribution across the growing area.
  3. Create Drainage Holes: Drill multiple holes around the bottom of the growing area tote to facilitate excess moisture drainage back into the reservoir.
  4. Thread Wicks: Pass the wicking cords through the drilled holes, ensuring they hang low enough to reach the bottom of the reservoir tote.
  5. Adjust Tote Lids: Remove the inner sections of the tote lids to prevent the top tote from sliding into the bottom tote.
  6. Position Wicks: Allow the wicks to drape over the top bucket’s lip, securing them with the cutout lid. This prevents wicks from getting covered while filling the bucket with media.
  7. Add Filter Layer: Place expanded clay pebbles or river rocks at the bottom of the growing area tote to prevent perlite and vermiculite from entering the reservoir.
  8. Prepare Media: Thoroughly rinse to remove dust by creating a 60/40 mix of perlite (60%) and vermiculite (40%).
  9. Integrate Media: Add the perlite/vermiculite mix to the top tote, ensuring wicks stay in place to prevent media displacement.
  10. Optional Aeration: If using an aerator, drill holes on side of the bottom hole about 2 inches below the handhold. Maintain consistent air line length for uniform pressure.
  11. Prepare Reservoir: Pour 2 to 3 gallons of water into the nutrient reservoir (bottom tote). Mix plant-specific nutrients and adjust pH as necessary. Test the aerator’s functionality if applicable.
