- It helps in maintaining the circadian rhythm, a biological process that regulates the day and night cycle, and the growth rate of the plants, ensuring they receive sufficient rest for their growth.
- Light intensity, duration, and wavelength affect plant growth and morphology, like stem length, leaf area, chlorophyll content, and flowering.
Varieties Of Light Used For Hydroponic Plants
Various types of artificial light sources can be used for hydroponic plants, as mentioned in the following points:
- Fluorescent lights are relatively cheap, efficient, and well-suited for seedlings and vegetative growth stages.
- High-pressure sodium (hps) lights emit orange and red wavelengths, making them ideal for the flowering stage due to their ability to promote bud formation.
- Light emitting diodes (leds) are energy-efficient, long-lasting, and provide full-spectrum lighting, making them ideal for all stages of plant development. They also produce minimal heat, reducing the risk of heat damage to the plants.
- Metal halide (mh) lights produce blue and white wavelengths, making them suitable for the vegetative stage as they promote vegetative growth.
By understanding the importance of light in the hydroponic plants, the growers can optimize the quantity and quality of their crops. Using the appropriate light source specific for each plant’s growth stage is imperative to ensure optimal growth and harvest.
Ideal Light Intensity For Hydroponic Plants
Science Of Light And Plant Growth
Before we dive into the ideal light intensity for hydroponic plants, it’s crucial to understand the science behind light and plant growth. Plants use light to undergo photosynthesis, the process of converting light energy into chemical energy, which is necessary for their survival.
Different light spectrums affect plant growth, and hydroponic growers can optimize plant growth by selecting the right light sources. Plants primarily use blue and red spectrums, with blue light used more for vegetative growth, and red light being more beneficial during flowering.
Optimal Light Intensity For Vegetative And Flowering Stages
When it comes to the ideal light intensity for hydroponic plants, it varies depending on the growth stage. During the vegetative stage, an ideal light intensity range is between 400-600 micromoles per square meter per second (μmol/m²/s). On the other hand, plants during the flowering stage require higher light intensity, ranging from 600-900 μmol/m²/s.
It’s important to note that too much light can harm plant growth and development. If the light intensity is too high, the plant can experience light burn, which can turn the leaves yellow and damage the plant.
Factors Impacting Light Intensity
Several factors impact light intensity, which should be considered when calculating the ideal light intensity for hydroponic plants.
- Type of light source: The type of light source used plays a crucial role in the intensity output. Led lights are more energy-efficient but have a lower intensity output, compared to high-intensity discharge (hid) lights.
- Distance from the light source: The distance between the light and plants determines the intensity received by the plants. The further the distance, the lower the intensity.
- Light cycle: The duration of light exposure affects plant growth and development.
- Reflectivity of the growing environment: The reflectivity of the growing environment can impact light intensity, and the use of reflective materials can increase light intensity.
- Plant species: Different plant species require varying light intensities to support optimal growth and development.
By understanding the science of light and plant growth and considering various factors impacting light intensity, one can calculate the ideal light intensity for hydroponic plants. By providing the right light intensity, plants can grow healthier and produce larger yields, leading to successful hydroponic growing.
