If the temperature is too high, the internoid spaces of the stem plants are exaggeratedly long and their leaves, small; Rosette plants are bad (these are the same symptoms as in the case of a lack of light). If the temperature is insufficient, the plants cease to grow and eventually die.
Temperature too much or not high enough, or poor heat/light ratio or heat/nutrients. The higher the temperature, the faster the plants grow. If the lighting or nutrients are insufficient, growth is embarrassed. When the temperature is high, the breathing of the plants is much more intense; They consume more oxygen and produce more carbon dioxide. When it is hot, the amount of oxygen consumed by breathing is greater than that produced by photosynthesis, which leads to a lack for the environment.
Check the temperature, light and nutrients, and correct errors.
