Direct sunlight and high temperatures should be avoided as much as possible. This may sound contradictory, because light and heat are essential for the growth of plants, for the so-called photosynthesis. For the best growth there should be a good balance in climate between temperature, light and humidity. A plant in direct sunlight and high temperatures also needs a high humidity, which is often lacking in room conditions. Without the combination of these three elements, the photosynthesis process quickly decreases or stops altogether.
