ମୁଖ୍ୟ ତଥ୍ୟ

• Completely passive — no pumps, electricity, or moving parts
• Capillary action pulls nutrient solution from reservoir through the wick into the medium
• Common wick materials: cotton rope, felt, nylon string, or fibrous growing media
• Best for small, low-demand plants: herbs, lettuce seedlings, succulents
• Not suitable for large, thirsty plants — wick cannot deliver nutrients fast enough
• Growing medium must be fine enough for capillary action: coco coir or perlite-vermiculite mixes
