The culture temperature is a very important determining factor. If the growing temperature is not correct, the plant will grow less or not at all.
It has been discovered in science that the best temperature around the leaf is 24 C ° - 26 C ° for each crop for maximum growth and flowering day and night.
During the day the plant makes energy to grow (assimilation) and at night the plant uses energy to grow (breathing).
The art of growing is to ensure that the plant makes as much energy as possible during the day and uses as little energy as possible at night.
We can stimulate this during the day by adding a little more CO2 and lumen (light) and stimulating the evaporation under the leaves (in adult plants) by using. air circulation. Be careful of course for too high evaporation.
The biggest growth is where the? hole? between Assimilation and breathing is the greatest. However, if it were 27 C during the day, to get the same optimum growth at night, the difference could be brought down from 3 C to 21 C. However, the temperature should never fall below 20 ° C, because then Phosphorus will be difficult to transport.
