A string of red
Alias: Salvia, Red Under Wall, Grass Ivory Red
Ecological Habits: Native to South America, this plant thrives in sunny conditions and is somewhat tolerant of partial shade. It prefers well-drained, loose, neutral soil that is rich in nutrients. However, it has limited cold tolerance and isn't very heat-resistant. The ideal growing temperature ranges between 20-25°C. When temperatures drop below 15°C, the leaves may turn yellow or fall off, while above 30°C, the flowers and leaves tend to become smaller. It is a perennial herb, but is often grown as an annual.
Cultivation Management: This plant can be propagated through sowing or cuttings. Sowing is typically done indoors or in a greenhouse from February to March, and seedlings can be moved outdoors in early summer. In June and July, shoots about 12-15 cm long are commonly used for propagation. After transplanting, it's important to provide some shade to help the plants adjust. Seedlings should be transplanted into pots with proper soil before being planted outside. During winter, the parent plants should be brought indoors, and cuttings can be taken for winter propagation. Maintain a room temperature of around 20°C. Roots usually develop within about 7 days, and after 14 days, the plants can be repotted. Whenever propagating, it's recommended to pinch back the seedlings when they reach 15 cm in height to encourage branching and create a dense, bushy growth. If you want flowers by October 1st, make sure to pinch them back before September 5th. For flowering by May 1st, pinching should occur around April 5th. Regular fertilization, watering, and weeding are essential, along with proper drainage during the rainy season to prevent waterlogging.
JRT usb interface distance sensor board adds a USB port to a Laser Distance Sensor, inexpensive laser distance measurement sensors, allowing customers directly using GBeacon-2.3-Fx.exe software to control the rangefinder sensor. Usb laser distance sensors are the the most popular model devices, it works by measuring the phase of an visible-red laser beam that reflects on the target. Usually, customers would like to choose CH341SER.EXE version to test.
