Ceramic plate on top of the reservoir will absorb moisture, moisture absorption over the reservoir,if the water level buoy sinking,means it\'s the time watering 4.What material for the Pot? This product is a PP material, PP has good resistance to stress cracking resistance, a high bending fatigue life, commonly known as "pleated plastic."PP products lightweight, good toughness, good chemical resistance. Commonly used crisper is made of PP material.
