how does humidity affect plants

The plant may show signs of leaf curl, brown patches, drying up, flower buds that dont open fully (called blasting), and flowers fade faster. Evaporation increases because there is a higher amount of energy available to convert the liquid water to water vapor. In fact, it can be harmful.

Plants need humidity because they evolved in places that have high humidity. I'm interested in a more scientific answer, so I thought it was more appropriate to ask here rather than r/gardening . When the leaves leave the soil, the humidity is reduced even more and this helps reduce the high humidity levels. Unfortunately, this also means photosynthesis is slowed and subsequently, so is plant growth. Concerns of Ethylene in Greenhouse Production. The relative humidity is expressed as the percent water vapor in the air in comparison to the total amount of water that could be held by the air if it were saturated. Plants do best at a relative humidity of 70 to 80 percent, a level that is difficult to maintain in the home. Most houseplants raise humidity because they undergo respiration and photosynthesis. Most of our houseplants are from rainforests, where the moisture is dripping from the trees. Damping down the benches and surrounds, also misting leaves will keep the air moist.

If the humidity is too low, plant growth is often compromised as crops take much longer to obtain the saleable size. By maintaining optimal relative humidity levels in a greenhouse and other growing environments, you ensure optimal plant transpiration. Relative humidity levels affect when and how plants open the stomata on the undersides of their leaves. This causes heat to build up in the plant tissue, and in temperature too hot the plant actually cooks itself. The only thing that makes a similar difference is light. Transpiration is happening in plants almost continuously and is a little like our sweating. Typically, these problems are seen in the winter and early spring, when air temperatures in the greenhouse are low and transpiration is inadequate, or during the hot, humid summer months.

Likewise, if humidity is very low and subsequent transpiration is too high, the plant closes its stomatal openings to minimize water loss and wilting. The stomata of plants growing in the Negev Desert, namely the stomata of the mesomorphic leaves of Prunus armeniaca, the xeromorphic stems of Hammada scoparia, and the succulent leaves of Zygophyllum dumosum, respond to changes in air humidity. Low humidity can have a number of negative effects on plants. If the weather is cold, the relative . Low humidity not only causes growth defects like brown spots on the leaves and leaves totally drying up, but it can also cause the plant stress.
