Growth lamp light radiation and its effect on rose growth in the greenhouse

Light is one of the key factors for photosynthesis, growth and flowering of plants. In greenhouses, providing sufficient and quality light is essential for the growth of cut roses. The use of Grow Light is very effective, especially in areas with little natural light or in seasons when light intensity decreases.

1. The importance of light for rose growth

  • Photosynthesis: The production of carbohydrates to provide the energy necessary for plant growth.
  • Growth and flowering regulation: Specific wavelengths of light (such as red and blue) have a direct effect on stem, branch, leaf and flowering development.
  • Photoperiod control: Photoperiod is effective in stimulating flowering and regulating the plant's growth cycle.

2. Characteristics of grow light for roses

Growth lamps must produce light with the appropriate spectrum for photosynthesis and growth. Sunlight contains different wavelengths, but for plants, the blue (400-500 nm) and red (600-700 nm) wavelengths are more important.

Types of light used:

  • Blue light: Stimulates vegetative growth (leaf and stem growth), increases plant density and reduces excessive stem height.
  • Red light: Stimulates flowering, improves flower quality and increases flower size.
  • Full white light (Full Spectrum): Simulates natural sunlight and is suitable for all stages of growth.

3. Effect of growth lamp light on rose growth and flowering

A. Vegetative growth (Leaf and Stem Development):

  • Increase photosynthesis and production of nutrients for growth.
  • Strengthen stems and reduce abnormal elongation.
  • Improve leaf color (darker green due to increased chlorophyll).

B. Flowering:

  • Increase the number of flowers produced.
  • Improve the color and quality of the petals.
  • Accelerate flowering time if sufficient red light is used.

C. Flower durability:

  • Reducing light stress and increasing the quality of the stem and leaves leads to a longer shelf life of the flowers in the environment after harvest.

4. Types of growth lamps suitable for rose greenhouses

A. LED Grow Lights:

  • Advantages:
  1. Low energy consumption and high efficiency.
  2. Produces precise light spectrum (blue and red or full spectrum).
  3. Long lifespan (over 50,000 hours).
  4. Reduces heat generation (prevents heat stress).
  • Application: Suitable for long-term use in greenhouses.

B. Fluorescent lamps:

  1. Advantages:
    • Cheaper than LED.
    • Produces white light suitable for early stages of growth.
  • Disadvantages:
    • Lower light intensity and more heat generation than LED.

C. High Intensity Discharge (HID) Lamps: Light Intensity:

  • Rose flowers require a light intensity of about 10,000 to 12,000 lux for optimal growth.
  • It is essential to use lamps with sufficient power to provide this light intensity.

B. Photoperiod:

  • Roses need a long photoperiod (14-16 hours per day) to flower.
  • Growth lamps can simulate this period.

C. Distance between the lamp and the plant:

  • The appropriate distance between the lamp and the plant (30-50 cm) should be maintained to provide sufficient light to the plant and prevent damage from the heat of the lamp.

6. Benefits of using a growth lamp in a rose greenhouse

  • Increase production: Produce more and higher quality flowers.
  • Improve flower quality: Brighter color, more resistant petals and larger size.
  • Environmental control for you
