Plant growth lights can be used for indoor gardening, plant propagation and food production, including indoor hydroponics and aquatic plants, and can also be used in homes. It is an artificial light source, usually an electric light source, designed to stimulate plant growth by emitting an electromagnetic spectrum suitable for photosynthesis. Plant lights are generally used in applications that do not have natural light or require supplementary light. For example: in winter, when the possible daylight time may not be enough to achieve the desired plant growth, lights are used to extend the time the plants receive light. If plants don't get enough light, they will stop growing.
Best LED Grow Light can provide a spectrum similar to the sun, or provide a spectrum more suitable for the needs of the cultivated plants; it can simulate outdoor conditions with different colors, temperatures and spectral output required for plant growth, and change the lumen output (intensity) of the lamp ; At the same time according to the type of plant cultivated, the cultivation stage (such as germination, vegetative period, flowering period, fruiting period) and the photoperiod required by the plant, the specific range of the spectrum, the luminous efficiency and the color temperature are all desirable.
1. FLUORESCENT (CFL) fluorescent growth lamp
CFL stands for "compact fluorescent lamp". You can buy these lights in many places, including household goods stores and even most grocery stores. They are particularly suitable for small-scale growth and the manufacture of affordable starting lights.
Advantages: Their availability and low cost are one of the advantages of CFL grow lights. These bulbs have standard sockets, so you can use them with any standard light fixture. The commonly used CFL used to grow cannabis ranges from 40W to higher. They have various color temperatures, such as "sunlight" at 6500K or "warm white" at 2700K, with a redder spectrum. The bulbs with the "daylight" spectrum are more suitable for the vegetative growth stage, while the "warm" CFL with more reddish light is more suitable for the flowering of plants.
Disadvantages: Compared with other types of growth lighting, the light output of CFL bulbs is lower. If you want to provide them with sufficient light, you must place the CFL bulb very close to your plants. Unless you are willing to use multiple CFL bulbs, CFL is usually better for smaller growths, for example, if you only grow one or two plants. On the other hand, the "daylight" CFL grow light can be an ideal grow light for clones and seedlings.
2. HID GROW LIGHTS (MH&HPS) high intensity discharge lamp/high pressure neon lamp
There are two main types of HID lamps, MH (metal halide) lamps and HPS (high pressure sodium lamps). The difference between the two is that the MH lamp presents "cooling", blue light, while the HPS lamp is at the red end of the spectrum. This makes the MH lamp more suitable for the vegetative period of the plant and HPS more suitable for flowering.
Therefore, most advanced growers use the MH/HPS combination during their growth. If for some reason you need to choose a type of HID for your entire growth, you should get an HPS light. Growers who want to grow with HID lighting can usually get a complete set of bulbs, ballasts and reflectors.
Advantages: Compared with other types of grow lights, the initial cost of HID lights is much lower. They are easy to install and operate, and proven standardized solutions can achieve excellent results.
Disadvantages: A powerful HID lamp of 600W or higher can generate a lot of heat. This means that your planting room needs adequate exhaust and vents. In addition, because HID bulbs degrade over time, they have a limited lifespan. You will have to replace the bulbs regularly. Some growers get new bulbs every year, while others grow longer.
HID lamps cannot be plugged into conventional lamp sockets because they require special lampshades and ballasts. Therefore, they are very power hungry and can significantly increase electricity bills.
3. LED GROW LIGHT
LED lamps will replace metal halide HID lamps because of their high efficiency and low economic cost in plant cultivation. The LED plant lights used in the plant cultivation industry have the following characteristics: rich wavelength types, just in line with the spectral range of plant photosynthesis and light morphology; the spectral wave width is narrow at half width, and can be combined as needed to obtain pure monochromatic light and composite spectrum; Concentrate light of specific wavelength to irradiate crops in a balanced manner; not only can adjust the flowering and fruiting of crops, but also control plant height and plant nutrients; the system generates less heat and occupies a small space. It can be used in a multi-layer cultivation three-dimensional combination system to achieve low heat The load and production space are miniaturized; in addition, its exceptional durability also reduces operating costs. Therefore, it can be seen that LED plant lights are very suitable for plant cultivation in a controllable facility environment, such as plant tissue culture, facility gardening and factory seedlings, and aerospace ecological life support systems.
What is the best led grow lights?
YOULUMI's YL-GL-O (320W, 640W, 960W) & YL-GL-P (120W, 240W, 320W, 450W) series products are the best led grow lights, which are high-performance top light solutions for commercial horticulture cultivation. They use a 10V dimming function source to control PPFD to meet every growth stage of plants and leafy fruits. They are the best alternatives to traditional halogen lamps and sodium lamps, and are suitable for greenhouses, vertical agriculture, hemp cultivation, etc. YOULUMI is a manufacturer and service provider specializing in the production of LED lamps. It has 10 years of experience in R&D and production of LED lamps. The PPF of its LED plant lamps reaches 2.8- 2.9 μmol/J(estimated), with sufficient light energy, which can make plants grow strong and fast. YL-GL-O series products are distributed light BAR design, which can fully reduce the light to the plant surface, make the plant receive uniform light and grow well. It uses Samsung 3030 lamp beads or Seoul Semiconductor white LEDs + EVERLIGHT 660nm red light lamp beads, professional The spectrum is more suitable for the growth of plants at all stages.
