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.
Can room light replace sunlight for plants?
Researchers can successfully grow plants using only artificial light in growth chambers. But sunlight is best for most plants. It’s generally more intense than artificial light, and it’s pretty equally distributed among the different wavelengths that earthly plants have evolved to like best.
Can any LED light be used as a grow light?
You can use any LED bulb to grow plants if they are emitting enough light. Plants often also look for warmth to come from the light source and we know LED bulbs do not provide much of that.
Do plants need direct sunlight or just light?
Plants that require full sun must grow outdoors and receive many hours of direct sunlight each day. Houseplants are a different story. … Nonetheless, many indoor plants manage just fine with indirect sunlight. The indirect natural light that pours onto a windowsill can be more than enough to feed a growing plant.
Can you leave a grow light on 24 7?
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 indoor lights help plants grow?
If you’re trying to grow houseplants indoors, you’ll find that some rooms of your house are low in natural light. 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.
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.
How do I choose an indoor grow light?
Grow lights should provide the proper spectrum of light for photosynthesis, which key to plant growth. Before purchasing a light, be sure to check out the provided color spectrum. Lights that can provide a full spectrum are the ideal choice for your growing space. This is where LED lights come in handy.
What is the difference between a grow light and a regular light?
Obviously, these are two very different lights used for very different purposes. Grow lights are very specifically constructed to aide in various stages of plant growth. Regular lights are made for everyday use, and although many are used for specific purposes, they all are based on human needs and consumption.
How do I know if my plant is getting too much sun?
Symptoms of Too Much Sun
- Color: Pigments will look washed out and bleached.
- Burns: Leaves eventually get blotchy burns in white, yellow, or brown.
- Texture: Over-exposure is often accompanied by signs of desiccation e.g. wrinkled, scaly, or crispy leaves.

How do you know if your plant is not getting enough 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!).
Do plants still get light on cloudy days?
Without sunlight, the plants are unable to convert nutrients and carbon-dioxide to energy through the photosynthesis process. On cloudy days, they produce much less of the energy they need to grow and bloom.
Do plants grow better with 24 hour light?
The Dark Side of Photosynthesis
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.
Can plants get too much light?
Plants cannot get too much light, but they can get too much of the heat energy that comes with the light. Photosynthesis and other plant growth processes will shut down when the environmental and tissue temperature gets high enough that all the water taken up by the plant is used to cool the plant tissue.
Can grow lights be on 24 hours a day?
It is not recommended to leave your grow light running for 24 hours straight. Twenty four hours of light can prevent a plant from effectively carrying out the respiration process. If your plant is not responding to 12 or 18 hours of light, you may need a stronger grow light or you may need to feed your plant nutrients.
