Can grow lights replace sun?

Grow lights can sometimes be better than sunlight, even if you have outdoor space too! Some plants prefer indirect or shaded light and wither under full direct sunlight. If you don't have any shaded outdoor space, your plants won't do well outside. Similarly, some plants prefer full, direct light.

Are grow lights as good as sunlight?

There's a lot more to photosynthesis, but for our conversation about LEDs, this is a perfect summary. While photosynthesis originally evolved as a reaction to sunlight, the development of indoor farming has proven that indoor grow lights can be as, if not more, effective than the sun.

Can light replace sunlight 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.

Does a grow light mimic the sun?

The sun fuels photosynthesis, but the right grow lights can simulate the sun's action. Although virtually any light will stimulate the growing process, not all artificial lights will provide the best conditions for growth. Some may run too hot, while others lack the spectrum of light for optimal growth.

What grow light is closest to sunlight?

Many LED lighting suppliers will say that full-spectrum LED grow lights are the best option for growing plants because they mimic the natural light from the sun.

Sunlight Vs. Artificial Light in Plant Growth

How do you mimic indirect sunlight with grow lights?

If you put your plants no more than 3-4 feet away from these lights, you'll get good results for “bright indirect light” type of plants. You might be able to support a few sun lovers right up close to the lights or if you put 4 lights together.

What can replace sunlight for plants?

Compact Fluorescent Grow Lights

While not as efficient or with as much intensity as HID lights, fluorescent deliver better color and spectrum light providing more useful light per watt to the plant.

Can you grow plants with just a grow light?

LED Grow Lights are perfect for indoor seed starting, as well growing as light-loving houseplants, such as orchids. With a set of grow lights, you can grow many plants indoors, including houseplants, orchids, and even some fruit and vegetable crops.

Can I leave my 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 grow lights have UV?

Yes, many LED grow lights emit UV rays.

UV rays, also known as ultraviolet radiation and ultraviolet light, are emitted from natural sources, like the sun, and artificial sources, like tanning beds and some kinds of lights.

How many hours a day should a grow light be on?

To be effective, grow lights really need to be on for at least 8-10 hours a day. This can vary up to 16 hours, depending on the conditions. That's why LED grow lights are so popular – when they have to be left on all day, it's best to use an energy efficient type! Always position a grow light above the plant.

Do grow lights give off heat?

Yes, every light produces heat. It does not matter if the light comes from a bulb, diode, or a star like our sun; they all produce heat. LEDs provide a more efficient means for converting energy to light than other methods and therefore produce less heat, but they can not break the laws of physics.

Can grow lights catch fire?

Traditional styles of grow lights like Halogen lights are still a major reason for fire breakout in residential areas due to huge amount of heat they can put off. But with advancement in technology and introduction of LEDs, the risk of fire is close to negligible in modern grow lights set up with Light Emitting Diodes.

Do plant grow lights use a lot of electricity?

The average daily energy consumption of a 600 watt LED grow light = 0.6 kWh x 16 = 9.6 kWh. That gives us a daily cost of 9.6 x 0.1375 = 1.32 dollarsper day living in the US. And for the UK residents, it's 9.6 x 0.28 = 2.688 pounds per day. Typically, a plant needs 14-16 hours of light per day.

Is artificial light the same as 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.

Are grow lights just LED lights?

What's the difference between LED lights and LED grow lights? Standard LED lights only provide illumination while LED grow lights have a wider spectrum of both blue and red light that promote vegetative growth and flowering, respectively.

Do indoor grow lights work?

All that said, they are very effective and are still widely used. If you want to grow large plants like tomatoes or lemon bushes, HIDs are good bet because the light penetrates farther into the foliage than with other bulbs. There are two types of HID bulbs.

Can you grow plants indoors without sunlight?

If you're hesitant to grow indoor plants because your home lacks bright sunlight, don't let the shady conditions stop you. Most plants need some light in order to grow, but shade-loving plants can easily get by with indirect light, or even artificial light from regular light bulbs.

Do LED grow lights count as direct sunlight?

It is UV light from the sun that burns plants. Grow lights wouldn't be considered "direct sunlight."

Do LED lights simulate sunlight?

LEDs can mimic the hue and intensity of natural sunlight and help to maintain the human body's natural circadian rhythm. This is because LED components allow for finer adjustments of color, brightness and intensity.

Can grow lights cause mold?

When the bulbs cycle off to cool down or imitate nighttime conditions, this moisture condenses again. It condenses not only on plants but also on walls and floors. This creates prime conditions for mold or mildew growth, which can pose serious structural and health dangers.

Can grow lights get wet?

Damp-rated LED lights can only be exposed to indirect water. Think of these as being in the laundry room, within a bathroom, or under a patio awning. There may be some slight moisture accumulation, but ultimately very little. Wet-rated LED lights may be within dripping or flowing water.

Are grow rooms safe?

Are grow tents a fire hazard? Grow tents are in general safe when you use quality equipment that is installed correctly. It's good practise to keep your grow tent clean and tidy from any flammable objects, using quality light installations, keeping electronics away from water, and don't overload circuits.

How warm are grow lights?

HPS/MH operate at extremely high temperatures – 3000⁰C/5400⁰F. Much of that heat gets turned into infrared radiation. Infrared is a type of radiation that causes molecules to vibrate and heat up when it hits them. This infrared gets directed down on your plants just like the visible light radiation does.

How much heat do grow lights put out?

As stated earlier, this is true regardless of what kind of light it is – LED, HPS, MH, or any other. Therefore, a 1,000W HPS grow light (1,060W with ballast loss) generates 3,617 BTU per hour heat. A 500W LED grow light (550W with driver loss) generates approximately 1,877 BTU per hour heat.
