Using a spectrometer to measure light quality and optimize growth in plants
This video takes an in-depth look at how a spectrometer can be used to measure the light quality, or spectrum, from light sources frequently used in greenhouse or grow rooms. As seen in Dave Johnson’s previous videos, plants respond differently to lights depending on the ratios of colors emitted from the light source. Having the ability to measure your light composition quickly and accurately can give you an upper hand in the optimization of your plant growth. Different ratios and combinations of colors that make up the light your plants are exposed to can control things such as the color of your lettuce, the taste of your vegetables, the heights and density of your stands, the yield of your cannabis, when flowering starts, etc. Dave, who is a Sr. Field Application Scientist at LI-COR, describes how a spectrometer’s advanced features can give growers interested in tinkering with “light recipes” the ability to have better optimization, control, and output of their vegetation.

What is light spectrum and how can you measure the light quality of grow lights?
มุมมอง 2.3K2 ปีที่แล้ว
While light intensity is one of the most influential inputs for affecting the growth of plants such as vegetables, fruits, flowers, and cannabis, light quality can play an equally significant role. The color-or proportion of colors-from a light source (even one that looks white) can have a significant impact on characteristics like yield, flowering inhibition or stimulation, disease resistance,...
Choosing a PAR light sensor for measuring grow lights and LEDs in greenhouses and grow rooms
มุมมอง 1.2K2 ปีที่แล้ว
With the explosion of controlled environment agriculture allowing everything from vegetables to flowers to cannabis to be grown year-round, measuring the light that plants need to optimize growth and yield has become even more important. This video, created by Dave Johnson, briefly explains what photosynthetically active radiation (PAR) is and how plants utilize this energy through the photosyn...

We want to quantify methane emission from cattle. Can we use this for this purpose?
Great
Can be used for tree and grass?
Yes!
this can be used for crop and trees both ?
How to use it on Irgason data from a sensor mounted on a helicopter?

Is there any training material like this for light response curve?
Wouldn't mind seeing a walk-through video (similar to some of the leaf-chamber videos) on some of these more advanced features of the chamber, with examples of starting flow rates, etc.
How to speed up the measure of data .it takes long time
Hi, if anybody wirked with this, can please write me
Yes
The music choice for this video is ridiculous
Thanks for the great explanation. I would like to know, any soda lime is suitable with the equipment and can properly remove CO2, or there is a specific one? I'm asking because most soda lime that I'm finding to sell in my region (São Paulo, Brazil), is for medicine/veterinarian use, to be use as anesthetic proposes. Thank you!
Specify the goal and need money
Helpful video thank you
Y luego.
You try to give the video more brightness it will be great if you do
the video image is too poor, you need to fix it more
How much
Some segments in the video are stamped not adjacent to each other
how much is it ? can it measure the respiration rate of fruits
Price plz
7 need to connect
How can I get li600
How much is it please
Really LI6400 can be controlled by remote?
Someone please upload a demo..
veeeerynice

Can you explain the procedure Of it more?
I'd like to put one next to my butt. heh-heh heh-heh-heh That would be cool.
