Research

If you are interested in learning more about plants, photosynthesis, and general lighting information, we've provided some pertinent articles that should get you started.  In the development of our light, we leaned on university researchers, professors and outside commercial lighting consultants to help our team collaborate and create superior plant grow lighting according to the most up-to-date research and industry practices.

 

Michigan State University is conducting a 4 year study to develop LED lighting for greenhouse crop growth.  Their website in general has A LOT of great information:

This article is particularly interesting:

This is a study which used color corrected filtered plasma light and halogen to mimic the suns irradiance.  Shows how much room indoor plant lights have for growth.  This is a very interesting read:

Brief article that explains the advantages of LED lights and their inevitable entry into horticulture:

This is an article that was written back in 2006 which was trying to re-create the suns irradiance with LED lights.  It was unsuccessful.  We believe with the advancements in LED's this project could be recreated and be successful.  We are working towards creating this experiment ourselves for research purposes.  Here it is (Unfortunately you will have to pay to get full access to this article):

This article displays the effect of mixing light wavelengths:

This article is very interesting and displays some of the wavelengths found to enhance tomato plant growth.  It shows the optimum conditions used to enhance tomato plant growth:

This is an interesting article that shows the different variations of temperature, PPFD (Photosynthetic photon flux density) and CO2 in the growth of Cannabis Sativa:

This is one of the first few studies that measured the action spectra of plants.  Of the 33 species tested, they all resembeled the same action spectrum curve.  There was some difference in light out of the PAR range, which is interesting and should be explored on a plant by plant basis.

This study shows the importance of green light in the growing of crops.  Too many LED manufacturers use NO green light.  Red and Blue light without the presence of green light has shown to have a negative impact.

This study was created to discern the effects of Near Ultraviolet light on plant growth.

Study conducted between Orbital Technologies and Purdue university about LED intracanaopy lighting.  While this study was mostly inconclusive, intracanopy lighting is the future of plant lighting
