'<p style="line-height: 1.75em;">Today I will talk about the effects of several types of grow lights, as well as some purchase suggestions and tips.</p><p><br/></p><p style="line-height: 1.75em;">I have used four types of grow lights, ordinary 60-watt fluorescent lamps, 27-watt LEDs, 35-watt LEDs, and 100-watt LEDs.</p><p><br/></p><p style="line-height: 1.75em;">The above is the actual power consumption of the lamp. I made a short video for your reference.</p><p><br/></p><p style="line-height: 1.75em;">The cost of a fluorescent lamp is about 40 Canadian dollars, two tubes and a light box. This was bought ten years ago.</p><p><br/></p><p style="line-height: 1.75em;">I have planted azalea seedlings, newly grafted hoyas, and various shorter plants. Because I have to be very close to the plants, the choice of plant varieties and quantities is very limited. The effect of the plants I have raised is acceptable. Succulents like this are actually quite shade-tolerant, and they can survive the winter even if the light is not too strong.</p><p><br/></p><p style="line-height: 1.75em;">Let&#39;s talk about the other three types of LED grow lights. Generally, when selling grow lights, they will say how many watts the lamp is. For example, this lamp that consumes 27 watts of power is claimed to be a 150-watt lamp. This is a more popular saying. I guess the seller wants you to think that you are buying a 150-watt fluorescent lamp or a traditional lamp. This 150-watt is not actually the output power of the lamp.</p><p><br/></p><p style="line-height: 1.75em;">Regarding the indicators of plant growth lamps, I generally look at two parameters. One is the spectrum. The spectrum must include the light bands required for plant growth. The other is the light intensity PPFD Map, which is in μmol.</p><p><br/></p><p style="line-height: 1.75em;">Generally, sellers will provide maps of light bands. But it is difficult for ordinary people to test, so you can only trust them. I usually choose white light, which is easy for the human eye to accept.</p><p><br/></p><p style="line-height: 1.75em;">Some sellers do not provide the intensity of light. This makes me feel unprofessional. I still try to choose those with parameters. And many buyers will actually test it, and I have tested it myself, so I trust the other indicators they report.</p><p><br/></p><p style="line-height: 1.75em;">Another useful function is waterproof, or a certain degree of waterproofness. Because some growing environments are very humid, such as ball orchids and orchids. They often need to be sprayed with water. A certain degree of waterproofness will extend the service life of the growth lamp.</p><p><br/></p><p style="line-height: 1.75em;">Well, this is the basic concept of purchasing LED growth lamps.</p><p><br/></p><p style="line-height: 1.75em;">Let&#39;s take a closer look at what plants I planted under my 27W, 35W, and 100W grow lights</p><p><br/></p><p style="line-height: 1.75em;">Here are two 27W lights, different brands, but the same OEM product, the lights are from the same manufacturer, just sold in different packaging. The instructions say the power consumption is 27W, which is about the same as what I measured.</p><p><br/></p><p style="line-height: 1.75em;">The reason why I use two is because the area of this light is too small. If the light is raised too high, the light intensity is not enough. Now the distance from the plant is about one foot. Look, there are osmanthus seedlings here, which have a higher demand for light. These ball orchids, bright spots and dark spots are not a big problem.</p><p><br/></p><p style="line-height: 1.75em;">Osmanthus has grown new leaves, which should be caused by the high temperature. The quality of the leaves can only be said to be compromised, far less than the effect of sunlight. Being able to survive the winter is the most important thing.</p><p style="line-height: 1.75em;">Ball orchids are different. Most of them are thriving.</p><p><br/></p><p style="line-height: 1.75em;">Look at this 35W one. The instructions say the power consumption is 35W. It is also equivalent to a 150W light. It feels better than the 27W light just now. Maybe it&#39;s because the area of the lamp is larger. In addition, the color is different. The color temperature is lower, which may be more suitable for human eyes. The main plants planted here are ball orchids. Most of them have new growth. Very satisfied.</p><p><br/></p><p style="line-height: 1.75em;">This is a 100-watt lamp, which is said to output 600 watts. I won&#39;t turn on the light now because it makes my eyes uncomfortable. I will compare the brightness of these lamps in a while.</p><p><br/></p><p style="line-height: 1.75em;">The plants here are mainly light-loving plants, such as Cattleya, Desert Rose, and Bougainvillea.</p><p><br/></p><p style="line-height: 1.75em;">The most favorite here is Bougainvillea, which grows vigorously. Other plants are also growing well. Although there is a big gap between the quality of growth under sunlight, I am already happy to see them blooming.</p><p><br/></p><p style="line-height: 1.75em;">I have a few small discoveries about the purchase of growth lamps. 1. Many lamps are OEM products, and you can choose the lowest price and good ratings. 2. There are often discounts. Save two dollars and buy a cup of coffee. 3. Some lamps will be sold together, which is cheaper on average.</p>'
