The lamps used by commercial growers are mainly selected according to the needs of plant growth. Common types include:
1. High-pressure sodium lamp (HPS)
Features: high light efficiency, red-orange spectrum, suitable for flowering and fruiting stages.
Advantages: high energy efficiency, widely used in crops such as cannabis and tomatoes.
Disadvantages: high heat generation, requiring additional cooling.
2. Metal halide lamp (MH)
Features: blue spectrum, suitable for vegetative growth stage.
Advantages: promote stem and leaf growth, often used for seedlings and leafy vegetables.
Disadvantages: low energy efficiency and short life.
3. LED plant growth lamp
Features: adjustable spectrum, suitable for all growth stages.
Advantages: high energy efficiency, long life, low heat generation, customizable spectrum.
Disadvantages: high initial cost.
4. Fluorescent lamp
Features: blue spectrum, suitable for seedlings and leafy vegetables.
Advantages: low cost and low heat generation.
Disadvantages: low light efficiency, suitable for small-scale planting.
5. Ceramic Metal Halide Lamp (CMH/LEC)
Features: The spectrum is close to natural light and suitable for the entire growth cycle.
Advantages: High light efficiency, full spectrum, and long life.
Disadvantages: High initial cost and high heat generation.
6. Plasma Lamp (LEP)
Features: The spectrum is close to natural light and suitable for the entire growth cycle.
Advantages: High light efficiency, full spectrum, and long life.
Disadvantages: High cost and less application.
Plant needs: Different growth stages require different spectra.
Energy efficiency: High-efficiency lamps are more economical in the long run.
Cost: Includes initial cost and operating cost.
Heat dissipation: Lamps with high heat generation require additional cooling.
Plant scale: HPS or LED are usually selected for large-scale planting, and fluorescent lamps can be selected for small-scale planting.
Summary
Common lamps used by commercial growers include HPS, MH, LED, fluorescent lamps, CMH and plasma lamps. When choosing, plant needs, energy efficiency, cost and planting scale should be considered comprehensively. LED lamps are increasingly widely used due to their high efficiency and spectral adjustability.
