Quick Answer: Is Blue Light Good For Seedlings?

How many lumens do you need for seedlings?

Understanding Lumen and Kelvin numbers is essential for growing healthy seedlings for transplants.

Lumens is the brightness or intensity of a bulb.

You want a lumen number between 2000 and 3000..

Why do plants absorb red and blue light better?

BLUE light carries a higher energy signature then RED light does and that higher energy with a shorter wavelength should provide the plants with a better environment for growth. Blue light has a wavelength that is shorter in the visible spectrum as compared to red light and has a higher energy.

Why does blue light cause the most plant growth?

Blue light helps with the plant’s production of chlorophyll–the green pigment that traps light energy and is integral to photosynthesis. In other words, blue light is easier for a plant to absorb and use the energy in photosynthesis. So, blue light increases plant growth and makes the plant reach maturity faster.

Should seedlings get 24 hours of light?

Yes, it is true that your seedlings need lots of bright light to grow healthy and strong—but they also need a period of darkness in order to thrive. … These fluorescent lights should be left on for 12 to 16 hours a day. Many people make the mistake of leaving their seedlings under fluorescent lighting 24 hours a day.

What color causes the most plant growth?

blueAs it turns out, blue appears to be the color that had the most plant growth in both experiments. Green was the lowest in both experiments, of course. Red was the second highest, violet was the third highest, and orange was the second lowest in both experiments.

What color LED lights for seedlings?

Light Color Red light stimulates vegetative growth and flowering (but if a plant gets too much, it will become tall and spindly). Blue light regulates plant growth, which makes it ideal for growing foliage plants and short, stocky seedlings (but too much will result in stunted plants).

How many watts do I need for seedlings?

In very general terms you need 15 watts per sq foot to grow seedlings.

What color LED light is best for plants?

Plants do best with a light that has a lot of red and blue and smaller amounts of green and yellow. White light is not important for plants – having the right amount of each wavelength is important.

Do blue LED lights cause algae?

Blue lighting can cause excess algae in freshwater and low Kelvin lighting, peaking in the red, can encourage algae in marine aquaria. Bulbs and tubes degrade over time, lowering their Kelvin rating, possibly causing more algae and producing light less useable by plants or corals.

What does blue LED light do for plants?

The effect of blue light on plants is directly related to chlorophyll production. Plants that receive plenty of blue light will have strong, healthy stems and leaves. … Red light is responsible for making plants flower and produce fruit.

Is blue light good for plants?

The effect of blue light on plants is directly related to chlorophyll production. Plants that receive plenty of blue light will have strong, healthy stems and leaves. Red light is responsible for making plants flower and produce fruit.

How far away should LED light be from seedlings?

For seedlings, LED grow lights should generally be mounted between 24-36 inches above the plant canopy – however, this depends on the power (wattage) of the light source.

Is blue light good for aquarium plants at night?

Blue lights do not hurt plants, they are called “moonlights”.

When should I give my seedlings light?

The answer to this one is simple. Your grow lights should be turned on (or your seedlings should be put under lights) as soon as the first seed starts to sprout. Many types of seedlings grow super fast, and they will start reaching for the light as soon as they emerge. So give them plenty of light right from the start.

Are LED lights OK for seedlings?

LED plant lights use less energy and emit less heat than compact fluorescent lights, reducing costs and simplifying temperature control in enclosed environments. Go with full-spectrum LEDs (which don’t look purple) for growing seedlings, propagating plants, and perking up houseplants in winter.
