Light plays a vital role in hydroponic systems by providing growth benefits, enabling light customization, supporting plant development, optimizing yields, and enhancing flavors.
Through adjusting light ratios, growers can manipulate the spectrum to influence key plant characteristics. By increasing red light, flowering and fruiting can be enhanced, while a higher ratio of blue light can result in stronger stems and bushier plants.
This customization allows for precise control over the growing environment, leading to healthier and more productive crops.
The ability to fine-tune light ratios in hydroponics offers a powerful tool for achieving specific goals and ensuring excellent plant growth and quality.
What is a light ratio?
Understanding light ratios involves analyzing the balance of different wavelengths in the spectrum received by plants in hydroponic systems. The light balance, or spectrum customization, plays a vital role in growth optimization and plant development.
By adjusting the ratios of specific wavelengths, such as blue and red light, growers can influence plant characteristics to achieve ideal ratios for their desired outcomes. For instance, tweaking the light mix can lead to enhanced flowering, fruit production, or overall plant size and quality.
Determining DLI and Light Ratios
Both the Daily Light Integral (DLI) and the blue/red light ratio are determined by the plant species and their specific growth stage. The DLI represents the total amount of photosynthetically active radiation (PAR) received over a 24-hour period, and it varies depending on the plant’s needs at different growth stages.
Let’s use basil as an example.
Example Calculation for Basil
1. Seedling Stage (2-3 weeks): During the seedling stage, basil sprouts tiny, delicate leaves after germination. The plant is small, typically about 1-2 inches tall, with two seed leaves (cotyledons) followed by its first true leaves. It requires careful watering and light for healthy growth.
- DLI: 6-10 mol/m²/day
- Light Ratio: 4:1 blue to red
- Calculation: For a DLI of 8 mol/m²/day and a light period of 16 hours: PPFD=8/(16×0.0036)≈139 µmol/m²/s
- Blue Light PPFD: 0.8×139≈111 µmol/m²/s
- Red Light PPFD: 0.2×139≈28 µmol/m²/s
2. Vegetative Stage (3-6 weeks): In this stage, basil rapidly grows taller, developing more stems and broad, fragrant leaves. The plant becomes bushy, reaching 6-12 inches. It’s important to prune regularly to promote leaf production and prevent early flowering.
- DLI: 12-15 mol/m²/day
- Light Ratio: 3:1 blue to red
- Calculation: For a DLI of 14.4 mol/m²/day and a light period of 16 hours: PPFD=14.4/(16×0.0036)≈250 µmol/m²/s
- Blue Light PPFD: 0.75×250≈188 µmol/m²/s
- Red Light PPFD: 0.25×250≈62 µmol/m²/s
3. Flowering Stage (6+ weeks): Basil begins forming flower buds at the tops of its stems. If not harvested or pruned, small white or purple flowers bloom. The plant may start to lose leaf quality, focusing more on seed production rather than leaf growth.
- DLI: 15-20 mol/m²/day
- Light Ratio: 1:1 blue to red
- Calculation: For a DLI of 18 mol/m²/day and a light period of 16 hours: PPFD=18/(16×0.0036)≈313 µmol/m²/s
- Blue Light PPFD: 0.5×313≈157 µmol/m²/s
- Red Light PPFD: 0.5×313≈157 µmol/m²/s
Practical Application
By determining the DLI and the blue/red light ratio based on the plant species and its growth stage, you can then work backwards to calculate the required PPFD. This ensures that your hydroponic system delivers the right quantity and quality of light, optimizing plant growth and yield.
Experimenting with these ratios allows for fine-tuning the growing environment to meet specific goals, ensuring that plants receive the perfect light spectrum for each growth stage. Ideal ratios, combined with the correct DLI, are key to maintaining healthier, more productive crops in hydroponic systems.
