Add more life to your garden with the best grow lights. If planning to plant, in that case, you need to know that there are 4 classes of bulbs that produce visible light that plants need to grow. The four classes are as follow:
- CFL (Compact Fluorescent Light)
- High-Pressure Sodium
- LED (Light Emitting Diode)
Incandescent is the weakest of them all followed by CFL, that came into existence in 1890 and became economically viable in the 1970s. The energy efficiency is 7-10% while it needs to be kept nearer to the plants in order to increase the efficiency. Then came the High-Pressure Sodium lights in the 1950s, they were used to grow vegetables but required a ventilation to avoid overheating. However, they didn’t face the issue of keeping them close to the plants for better results like in CFLs. These lights are priced higher than CFL and have shorter life span. Low Sodium emits low energy yellow wavelengths that aren’t good for optimal growth because plants require blue light (425-450 nm wavelength) and red light (600-700 nm wavelength). If we cater to the plants with these wavelengths then they’ll grow perfectly. The LEDs came in the 21st century that make it just about right for plants to grow.
