Yes, in the wick method, I saw the upper pot’s grow medium staying moist. The wick absorbed water from below and delivered it upward, keeping the roots hydrated without direct watering from the top.

Class 8 Vocational Education Chapter 1 Hydroponics: Growing Plants without Soil question answer
Yes, I clearly observed moisture in the upper pot during the wick system experiment. The cotton wick continuously pulled nutrient solution from the bottom container. This kept the upper grow medium (like coco peat or jute) damp, ensuring the plant roots had consistent access to water. It demonstrated how capillary action works and how passive hydroponic systems maintain hydration without needing pumps or frequent manual watering.
