The ability to control light has been a tremendous boon to the indoor horticulture industry. And while greenhouses that lock in warmth and sunlight have been around forever; the next evolution of indoor agriculture is taking shape in the form of light recipes.
As we further our understanding of light’s role in plant and flower growth, light recipes have become increasingly popular as well as important to the industry. Light recipes are growth methods that target the appropriate amount of light a plant needs and gives each unique plant the right amount and type of light to foster growth.
Of course, not all plants and flowers are created the same. Each one has unique needs and requires a different amount of light to optimize their growth. With light recipes, growers can determine the amount and type of lighting plan their plants need.
This results in optimal growth conditions, giving way to accelerated growth, higher yield, and more.
With optimal lighting conditions, LED horticulture lights can improve the growth performance of nearly all types of plants, flowers, and indoor crops. Plant production is increased by roughly 30% and in some cases, more.
In addition, the growth cycle is accelerated. Plants and flowers grown under optimal lighting conditions reach peak harvest more quickly. In addition, light recipes can also lead to increased biomass.
For example, when LED light recipes contain around 16% blue light, biomass increases. This yield plants with larger leaves and more cultivatable product.
The Role of Colour
There are several factors that impact the growth of both plants and flowers. Colour is one such consideration. We’ll dive into the role of colour on plant and flower growth in a later article. However, here is a primer on the general effects of colour on growth.
- Blue Light (400 to 520 nm)
- Most absorbed by chlorophyll in the plants
- The quality and power of blue and violet emissions strongly promote plant growth and photosynthesis.
- Red Light (630 to 660 nm)
- Increases light absorption in the plants
- Growth and budding of the plant are present when red light is used
- Far-red Light (720-740 nm)
- Increased plant biomass
- Germination and flowering are present
There are many variables to consider when it comes to ideal plant growth. Colour, wavelength, time, and more all have an impact on the growth cycle and yield of your plants and flowers. Emerging research in light recipes are leading to exciting developments in the indoor growth market.
Light recipes continue to develop into a niche market. Several large smart LED lighting companies are working to create and develop the ideal mixture of time, colour, and intensity. As more research emerges in this growing field, light recipes will continue to develop. As we improve our understanding of the role each of these factors play in the development and life cycle of plants and flowers; better growth and yield is on the horizon.
