Sistem wick adalah bentuk hidroponik pasif yang paling sederhana, di mana sumbu penyerap menarik larutan nutrisi dari reservoir ke media tumbuh melalui aksi kapiler. Tanaman menyerap kelembapan dari media sesuai kebutuhan tanpa memerlukan pompa, listrik, atau pengatur waktu.
Fakta utama
- Completely passive β 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 β wick cannot deliver nutrients fast enough
- Growing medium must be fine enough for capillary action: coco coir or perlite-vermiculite mixes
