Yes ,it can, Both photosynthesis and respiration work normal in the light with no problem . ... Most plant species will grow fine under continuous light, although some (e.g. tomato) cannot. If the species is photoperiodic, flowering will obviously be affected.
Should I leave a grow light on 24 hours?
A: In general, you should not leave grow lights on 24/7 . Plants need a light-dark cycle to develop properly. It's believed that they truly do “rest” during periods of darkness, and probably use this time to move nutrients into their extremities while taking a break from growing.
Do plants grow better with 24 hour light?
During light reaction, the plant absorbs light and turns it into energy. ... Because dark reactions do not require the absence of light, plants will remain healthy when exposed to light 24 hours a day . There are some plants, however, that will survive but not thrive without darkness.
Will plants grow better with or without light?
ANSWER: In a strict sense, plants do not grow faster in the dark ; they grow slower. However, plants seem to grow faster in insufficient light due to rapid cell elongation. ... In conditions of total darkness, plant cells will generally expand upward, a process called geotropism.
Does stronger light make plants grow faster?
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.
Is too much LED light bad for plants?
The reality is that modern LED grow lights can produce a very high level of light and it can cause photo-bleaching and burn leaves. This depends very much on the plant, but a PPFD of 800 is enough to damage some plants .
Is light at night bad for plants?
Potential Problems. While leaving growing lights
Is room light enough for plants?
Sunlight is the perfect balance of wavelengths necessary for plant growth and blooming, but you can also use artificial light to help your plants along. In fact, low-light foliage plants (such as pothos and peace lily) can grow quite nicely in windowless offices with enough artificial light.
Are house lights enough for plants?
For most hobbyist growers, indoor lighting will not be enough to keep your plant as healthy as it would be outside. However, with the best equipment, it is possible. The main problem with growing plants indoors is the cost involved. Buying the right lamps and bulbs that replicate the sun can get very costly.
What happens when a plant gets too little light?
When plants lack light, they don't produce chlorophyll (the green pigment in plants), and plants can turn pale green to yellow to white. ... Flowering plants may fail to produce flower buds. Plants exposed to too much light may result in scorched and bleached leaves .
Do different colored lights affect plant growth?
Different color light helps plants achieve different goals as well. Blue light, for example, helps encourage vegetative leaf growth. Red light, when combined with blue, allows plants to flower. Cool fluorescent light is great for cultivating plant growth indoors.
Do red and blue lights help plants grow?
While red is most efficient for photosynthesis, having only red light would result in poor growth such as very elongated stems, so blue is added to keep plants compact and a more typical shape.
Why do plants grow better in blue light?
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.
How do you know if your plant is getting too much light?
If your plant is not getting enough light, the most common sign is the yellowing and dropping of leaves, stunted leaf growth, elongated stems, and a dull-green color. If your plant is getting too much light, then its leaves will have singed tips, burned patches, or will be falling off (yikes!).
How far should my LED grow light be from my plant?
There is no universal rule for setting the distance but it's recommended that LEDs are placed 12 to 18 inches away from the plants. Light is among the most vital factors to consider when growing plants because it triggers the photosynthesis process.
How close do grow lights need to be to plants?
TIP: Place grow lights directly over plantings to mimic natural sunlight. As a rough guide, incandescent grow light bulbs should be at least 24 inches over your plants . Fluorescent and LED lights have a lower heat signature, so they can be placed 12 and 6 inches over plants respectively.
