These rooms include the kitchen, bathrooms, basements, and laundry room. The relative humidity is the amount of water vapor in the air relative to the maximum amount of water vapor that the air can hold at a certain temperature.

Optimal transpiration rates vary by plant type, age, and season, making climate control for plant growth necessary throughout the year. Many of the growth responses of plants to such things as light intensity, relative humidity, air temperature, and wind velocity can be explained on the basis of the direct effect of these .

If the air is excessively dry and the plant is wilting, the stomatal openings close, thereby reducing photosynthetic activity and ultimately plant growth. This process is natural, but if there isnt sufficient water in the potting medium to be drawn up into the plant to transpire, some damage will occur. Also, low water usage from the growing medium often correlates with climbing growing medium pH, which makes micronutrients such as iron unavailable to the plant. Plants use two main methods to sense sounds: 1) by using pressure changes in the soil caused by vibrations; 2) by detecting airborne particles that enter the root system. Plants can also be used to help control humidity in your home. Ideally, monstera like high humidity. This requires a lot of water.
