Color Temperature (Kelvin) Means Almost Nothing For Plants
Consider this, your eye can mostly pick up green and yellow, that’s it. White LED manufacturers make the LED chips so that they can “score” the highest lumen rating (the light your eyes can see).
In this manner, is 6500k good for plants?
Foliage growth is generally best around 6500K, though many plants need a period of warmer light, around 3000K, in order to produce flowers, and thus fruit. In other words, if your goal is to simply produce seedlings, leafy green vegetables, or root crops, you only need higher spectrum bulbs.
Also to know is, which color light is best for plants?
What Color Light is Best for Plant Growth?
- Violet-blue light in the 400 – 520 nanometer range encourages chlorophyll absorption, photosynthesis, and growth.
- Red light in the 610 – 720 spectrum range promotes flowering and budding.
Why does blue light help plants grow?
Blue light produces more lush greenery. Blue light is necessary for plants to regulate plant growth, as it helps to create strong stems and also helps create the chlorophyll necessary for plant processes. … In other words, the chlorophyll in the plant absorbs the red and blue light much more readily than the green light.
What is the best color temperature for grow lights?
As a general recommendation, choose a full spectrum grow light with a color temperature in the blue range (5,000 – 7,000K) to promote vegetative growth and choose a color temperature in the red range (3,500 – 4,500K) to promote fruiting and flowering.
Will 6000K LED grow plants?
The 50W , 6000K LED lights provides full spectrum light that’s optimal for plant growth.
Will 5000K LED grow plants?
Both 5000K and 6500K white light is great for growing plants, but not as great for flowering them. It will still work fine, but a warmer color temperature would work much better.
How many lumens does a plant need?
Light Brightness and Lumens
Vegetable seedlings and other “full sun” plants require about 2000 to 3000 lumens (at minimum) per square foot of growing space. So, if you’re growing just a single standard tray of seedlings, using a grow light that emits 3000 lumens is sufficient.
