Free Download: Key Aspects about the Use and Management of LED Lighting in Crop Production

As LED grow lights continue to become more affordable, an increasing number of greenhouse growers and vertical farmers are considering whether the lights would benefit their production systems. Several studies and growers applications have demonstrated the development of new lighting technologies such as light-emitting diodes (LEDs) can increase the capability to provide ideal light conditions to crops, making possible the improvement of crop performance and product quality.

Photons and Yield

Light incidence over our crops will have a direct effect on yield. Photosynthesis is the most important process in plants to produce energy. But how can we relate photons of light to yield? Based on research we know now one mole of photosynthetic photons is required in order to produce one gram o dried biomass (yield).

Stomata Behavior

Stomata are pores constituted by two cells called: Guard cells. Guard cells are hydraulic valves making possible stomata closure and opening. 

Stomata open or close depending on different factors: Light intensity, light quality, temperature, leaf water status, and intracellular CO2.

Aquaponics

Aquaponics is a technique used to grow plants and aquatic animals in a system using the recirculation of water. In order to understand aquaponics, we need to have knowledge about aquaculture, hydroponics, and bacteria. 

But how could aquaponics be a good option?

Hort Americas Brian Harris will be speaking at the 3rd Annual Controlled Environment Conference

December 9–10, 2021

The 2021 Texas A&M Controlled Environment: Urban Agriculture Conference is designed for new and prospective growers interested in specialty crop production under controlled environment and for experienced growers who want to learn more about the nuts and bolts of crop production in a controlled environment. This conference is also suitable for hobbyists and gardeners interested in hydroponic production.
