潮汐式水培（也称为涨落式水培）是一种水培系统，其中种植托盘会定期从下方的储液罐中注入营养液，然后完全排干。 湿-干循环在注水期间将养分输送到根部，并在排水阶段将氧气吸入根区。
关键事实
- Timer-controlled pump floods the grow tray 2–6 times per day depending on medium and crop
- Complete drainage after each flood oxygenates roots — reduces root rot risk
- Compatible with many growing media: rockwool, clay pebbles, coco coir, perlite
- Versatile — suits leafy crops, tomatoes, peppers, cucumbers, and cannabis
- Overflow fittings prevent flooding if the drain is blocked — a key safety feature
- Reservoir and pump size must match tray volume for reliable flood-drain cycles
