Humidity and climate
If we want to properly satisfy a certain requirement of a plant for living conditions, we need to clearly imagine the answers to the questions: "What should we do?", "Why?", "How much?", "When?" And "How?"
The first two questions are easily combined as the most obvious, and the rest is better to return a little later.
What should we do? Since in this section we are talking about the requirements for moisture, the task is to provide the plant with the necessary amount of moisture.
Why? Water is needed to him and directly as such( any living organism, although it is not obvious, consists mainly of this substance), and as a solvent of nutrients, and as a component of a certain medium( humidity - and microclimate in general, and onefrom the characteristics of the soil).
How much water does a flower need? The answer to this is already more complicated. The total quantity, the amount of water needed by the plant, must be mentally divided into how much the flower will "drink" along with the nutrient solution, how much should remain in the pot to ensure good conditions for the roots, and finally how much water should be present in the air for the aerial partThe question is rarely raised, but rather fundamental: excess or insufficient atmospheric humidity for species requiring special conditions may prove fatal).
A single board for calculating the exact amount of moisture for all colors does not and can not be!
If for irrigation plants the irrigation rules are more or less similar, then among the room colors, at least four groups should be distinguished, sharply differing in terms of moisture resistance: desert plants, dry subtropical plants, moist subtropical plants and tropical rainforest plants.
The selection of these groups is necessary not only for the correct selection of the irrigation mode, but also in order to determine the necessary thermal and light modes and to correctly place the flowers in the room. Knowing the peculiarities of climatic conditions natural for a given plant species, we should strive to recreate them in the rooms, or, if it is impossible, even to refuse the cultivation of certain flowers.
Climate is a multifactorial phenomenon. And what is the microclimate( in this flower-growing context), how is the climate not artificially created for the plant in the local area of space? Humidity, temperature and illumination are part of a single complex of climatic factors. It's pointless to talk about the microclimate as something completely separate from them. Yes, and remember all the particular requirements of plants for irrigation and spraying, without considering them as a consequence of adaptations developed by plants during evolution for different climatic zones, is very, very difficult. It is easier to remember the exceptions to the rules( more precisely, small deviations from them) for certain individual groups of plants.
Let's consider brief characteristics of climatic zones( they are purposely located not in a geographical order, as is customary, but according to the principle of availability of humidity, temperature and light) and the adaptations to their conditions that have arisen in plants.
