Please tell me about the use of plant fill lights.
1. High-pressure sodium lamps are the best and are commonly used in agriculture. But it often starts at 400W, which consumes a lot of power and generates high heat. Not practical for home use. But as far as I know, there are several flower gardening and sowing experts in the altar, and they all use this thing. 2. According to my experiments, the performance of special LED lights for plants is really poor. The power is not high, 80LED, about 2.2W according to actual measurement, which is extremely power-saving. But the effect seems to be directly proportional to the electricity bill, causing my seedlings to not grow well. It's so long that it doesn't exist, but it can still be used as a supplementary light when there's no sunlight. 3. Opple 40W three-primary color ring lamp, this is good. It doesn't consume too much electricity, and the effect is pretty good. It's a little worse than sunlight, but at least it can make my seedlings grow and develop normally. I'm very satisfied. I usually turn on the LED lights and 40W ring tube at 7 o'clock in the morning and turn them off at 9:30 in the evening. The location of the seedlings has no direct sunlight, so I rely on this supplementary light. . I will send a detailed comparison picture later. It seems that autumn planting is about to happen, and everyone is very interested in this.
