Grow lights simulate the solar spectrum and stimulate plant growth through a specific photosynthetic electromagnetic spectrum. Grow lights are suitable for environments where natural light is lacking or where supplemental light is needed, and cannabis has the characteristics of liking light. Lighting is of great significance to the production of cannabis. The intensity of sunlight or light intensity plays an important role in the reproductive process and gender expression of cannabis.
1. HPS lamps and LED lamps have become the main lamps for cannabis cultivation
Regarding cannabis grow lights, HPS lights and LED lights currently occupy the main market in the demand for cannabis lamps.
HPS lamps are also high-pressure sodium lamps and are commonly used by indoor flower and vegetable growers today. HPS lamps are often used as a single light source throughout the vegetative and reproductive stages. To put it bluntly, using HPS lights can make plants grow faster and illuminate a wide area. HPS lights produce a lot of light and are also particularly good for blooming. But at the same time, HPS lamps also generate a lot of heat.
All HPS lamps require a ballast to operate, each ballast has a specific wattage, and different types of bulbs have different starting and voltage requirements, as well as different operating characteristics and physical shapes. It's also important to note that mismatched bulbs and ballasts can stop working, or even burn out immediately.
LED lights consist of light-emitting diodes, usually in an enclosure with a heat sink or built-in fan. LED lights generally do not require a separate ballast, and can be directly plugged into a standard power socket for direct use, which is very economical and efficient, and LED lights can generate light of specific wavelengths. At the same time, the LED light can also have a precise broad-spectrum output, combining advanced optical and thermal control designs, and can convert almost 100% of electricity into planting and harvesting results. The LED lights also feature a broad spectrum of ready-to-use, ready-to-calibrate output for different growth stages.
2. Comparison of the advantages and disadvantages of HPS lamps and LED lamps
HPS Grow Lights have the same specifications and are relatively easy to choose from.
The HPS lamp is different from the broad spectrum curve of the LED lamp, and the irradiation area of the HPS lamp is wider.
In the past, the price of HPS lamps was cheaper than that of LED lamps, but due to the rapid development of LED lamp technology and the reduction of costs, the difference would not be much.
HPS lamps provide huge raw light intensity, so they can create huge yields and are more suitable for large-scale cultivation.
HPS lights generate a lot of heat and will require additional airflow tools to maintain the growing climate in the greenhouse.
After a period of use of HPS lamps, the light intensity gradually decreases, and in order to maintain production, it needs to be replaced every 12 to 18 months, which increases operating costs.
Special attention should be paid to the installation of HPS lights. Generally, pre-embedded junction boxes, hooks, screws, expansion screws, and other fixing methods are used for installation. It is strictly forbidden to use wooden wedges to fix and stay away from flammable structures.
