What is the effect of over ventilation on orchids

Excessive ventilation leads to scorching of orchid leaves.

The suitable humidity for orchid growth is 50-80%. Generally speaking, with the increase of air circulation, the water loss in the small environment will be accelerated, and the humidity will soon drop. Generally, the indoor temperature is higher and lower, and the air humidity on it will be smaller. The respiration of the leaf tip of the orchid leaf is stronger, because the water is not enough, the water will be poured.

Damage of orchid leaves caused by excessive ventilation

As the saying goes, the spring wind in February is like scissors, the wind is strong, the leaves shake violently, and the leaves rub against each other, which is likely to be broken. After breaking, the bacteria in the air enter into the orchid, and the whole orchid carries bacteria and bacteria, accumulating over time. If the orchid is light, the leaves will be damaged, black spots, broken, and if the orchid is heavy, the soft rot and stem rot will occur.

Don't despise that small wound. It's fatal to start a disease.

Excessive ventilation leads to empty roots of orchids

When the orchid leaves lose water and the water in the roots and bulbs is transported upward, the roots will quickly absorb the water in the soil, causing the soil to dry. The time of this change is very short. If the water is not watered in time or in the way before, the roots will be damaged, resulting in empty roots.

Ventilation and watering are like two couples. If one side is too strong, it is necessary to quarrel. If the environment is not harmonious and well ventilated, water more. Air roots are because the small environment around the roots is not suitable. If the roots are dry and wet, they will be empty. There is no direct relationship with ventilation. If the roots are not watered in a closed environment for one month, they will be empty.

Excessive ventilation leads to orchid fertilizer damage.

Under normal fertilization, the orchid will absorb and digest for a long time, and the soil fertility will decrease. However, due to excessive ventilation and drying of basin soil, the root of orchid can't absorb nutrients. The decrease of water content leads to the increase of soil nutrient concentration, which is beyond the tolerance of orchid, resulting in fertilizer damage and serious black root and root rot.
