How to judge light intensity for Phalaenopsis with the naked eye and the temperatures in degrees Celsius it likes

As more and more friends fall in love with Phalaenopsis, the varieties you can see on the market are more than you can count on ten fingers, among them some Phalaenopsis that bloom in summer and some that bloom in winter. However, no matter which variety you grow, what Phalaenopsis cannot do without most is control of light and temperature.

To grow Phalaenopsis well at home every day, as long as you master these few points, even a beginner can with a high probability grow brilliant flowers. First, let's talk about the light requirement. If you can provide plenty of sunlight during care, the roots can accumulate more nutrients, and whether it is growing new roots or the plant putting out leaves, it will become more vigorous. The light intensity suitable for Phalaenopsis is between 10,000 lux and 20,000 lux. This number sounds a bit abstract. If conditions at home allow, flower lovers can buy an inexpensive light meter and directly measure whether the place where they care for the plant is bright enough. If there is no light meter, you can also judge with the naked eye: place it in bright light, and put the leaves in a spot that feels hot from the sun, for example a spot by the window behind a thin curtain.

The principle for absorbing light is "on the premise of not getting sunburned, sun it as much as possible", and you also have to adjust flexibly according to the season and weather. For example, in summer the sunlight is relatively intense, so at noon the sun must be shaded, or just draw the curtains; in winter the sunlight is weak, and even the noon sun is mild, so let it get as much sun as possible, for example place it on a south-facing windowsill, and four or five hours of full sun is no problem.

In terms of temperature control, the roots of Phalaenopsis are relatively sensitive, and places that are too cold or too hot may prevent it from growing well. The most suitable temperature for root growth is between 18 and 30 degrees Celsius; at this time the roots will keep growing new roots and putting out crystal tips.

If the temperature is lower than 15 degrees Celsius, root growth will slow down, or even stop; if the temperature drops below 10°C, the leaves will gradually turn yellow and become soft. So in winter you must keep it warm. At night, put a wind-blocking plastic bag over the Phalaenopsis, and in the morning put it back in a warm place indoors as usual, for example a living room away from the window, or a room with heating or air conditioning.

An environment above 30 degrees Celsius will make the roots fragile and prone to root rot. Therefore try to put the flower in a cool, well-ventilated place, such as a north-facing balcony, or spray a little water around the flower pot, so that heat is carried away through water evaporation.
