Compare LED Grow Lights Vs HID Grow Lights

Growing plants indoors requires bringing sunlight indoors along with the plants. Grow lights that imitate sunlight are crucial for the successful cultivation of plants that aren’t allowed access to the real thing, and grow light technology has evolved to find the ideal kind of artificial light for plant growth. Both high-intensity discharge (HID) lamps and light-emitting diodes (LED) address issues of energy efficiency and light color, two of the biggest concerns for indoor gardeners.

LED Technology

A LED is a solid-state electronic device that produces light by passing an electric current through a diode composed of two materials, one electron rich and the other electron deficient. The current causes the electrons to move from the electron-rich material to the electron-deficient material, and the movement of the electrons produces light, which is focused into a beam by a plastic lens that envelops the diode. The chemical composition of the materials used in the diode determine the color of the light it emits.

Metal Halide HID Technology

Metal halide lamps, also known as HID lamps, produce light by passing an electric current through mercury and halide salts contained in a glass tube. When the lamp is turned on, a current is generated by the lamp’s ballast, and that current ionizes a gas, typically argon, within a container called an arc tube. The ionization of the gas allows an electric arc to be generated between the lamp’s electrodes, and the resulting increase in heat and pressure within the lamp vaporizes the mercury and halide, which give off light as they are vaporized.


Sunlight, which most grow lights attempt to emulate, is composed of light of all colors, or wavelengths, of the visible spectrum as well as invisible infrared and ultraviolet radiation. Metal halide lamps are capable of producing light very similar in color to sunlight and are thus well suited to use in grow lights. However, plants do not require the full spectrum of light wavelengths for optimal growth, and because the color produced by LEDs can be tightly controlled, LED grow lights can be more efficient by producing only the wavelengths of light that plants can use.

Power Consumption

Both metal halide lamps and LEDs are significantly more energy efficient than incandescent lamps. Metal halide lamps use approximately a fifth of the energy of incandescent lamps and last up to 25 times longer. LEDs are even more efficient thanks to the fact that nearly all their energy is used to generate light, with almost no heat being produced in the process; by contrast, incandescent lamps expend up to 90 percent of their energy in the production of heat. For the same reason, LEDs are more energy efficient than metal halide lamps as well.

Expert Advice On Growing Weed Indoors

Have you ever thought about growing weed indoors?  Many people grow inside of their own home because they save a whole lot of money, it’s safer than buying on the streets and they produce the same high quality bud every time!   Remember, not all states have dispensaries, so growing in your home is the only option for medical marijuana users.  If you are new to growing you will want to read this first, knowing about what mistakes I made will have you have a flawless grow operation.

First, you have to figure out what strains of marijuana are even suitable for growing indoors.  Some Sativa strains grow over 10 feet tall, so these will not be good for growing inside of your house.  After finding the right strain for growing indoors and that suits the type of high you like, you must set up your grow area.

Your grow area, whether it’s a grow closet, grow room or a stealth pc grow case, must have common elements to grow your weed at the most optimum level.  Ventilation is key because your cannabis plants need oxygen to grow and thrive! You can accomplish this by setting up an intake and an out-take fan to keep the air moving.

You must use the right type of lights because you are not then you will not have a successful grow.  The common light bulb can cause your plants to stretch because of the light frequencies.  Using led grow lights are great because of the light to grow effect, price and they use the right light frequencies to grow weed.

Nutrients are needed to feed your plants to help growth during vegetation and flowering periods.  Using nitrogen will help to mature the plant while using phosphorous during the flowering period is critical to grow the most potent buds around!

Hydroponic Plants for Hydroponic Gardening

You can build personal hydroponics garden any where around you. It is not very demanding and attention seeking method of gardening compared to traditional pot growing. It is soilless growing method. Hydroponics, also known as water culture, involves cultivation in water containing nutrients.

Ideally, soil acts as a nutrient reservoir but soil is not required for plant growth. The important nutrients plants need to grow can be absorbed by plants dissolved in water, and if these nutrients are supplied artificially there is no need for soil.

The water supply in hydroponics gardening can be automated and recycled, this lowers water cost. Hydroponics method does not require compost, because soil is not all-necessary medium for hydroponics gardening. In hydroponics system, important macro- and micronutrients are pumped through inert medium for advantageous hydroponic yields. Hydroponics systems can be carefully monitored if they are installed in a greenhouse or other controlled ambience. Ideally hydroponics is a science but it is also practiced as a hobby. Hydroponics makes plantation possible in places where you cannot imagine traditional gardening.

In traditional gardening, plants are destroyed by pests like, pin worms, white flies, leaf miners, nematodes, and diseases like root rot and bacterial wilt. Hydroponics method helps minimize risk of disease and pests, because the drained solution is sterilized, and hydroponic plants are given regular heat treatment and ultraviolet radiation. Growing plants is worthless if plants are destroyed by pests and diseases at the later stage of growth; therefore hydroponics is a standard technique to get bigger, pest-free and delicious hydroponic fruits and vegetables. For an efficient hydroponics management plan one should identify possible crop disease and insect problem and then accordingly use available solution to eradicate disease and insect problem.

Hydroponics can successfully help overcome unexpected food crises. Hydroponics is the future of mass cultivation; there will be reduced groundwater contamination and there will be no drainage system required. With the help of hydroponics there will be maximum control over the growth of your plants!

Garden Tips Light Intensity VS Brightness

One of the biggest causes of confusion and disagreement in the world of grow lighting is the word “brightness”. The problem is that we constantly use the word colloquially to describe how things “appear” to us – it’s a bright sunny day, that bulb is a bit bright, etc. It is no way a scientific definition of light intensity – the number of photons hitting a specific area over time – and ignores wavelengths of light that humans are less sensitive to.

Take as an example an X ray light source. Is this bright? Well you can’t see it and you wouldn’t be able to read a book using X rays. But when you consider that a very short burst from an X ray machine can pass straight through you onto a film plate, casting shadows only where your bones got in the way, you have to conclude that maybe brightness and intensity aren’t one and the same thing after all.

Likewise, because LED Grow Lights accurately target the wavelengths preferred by plants they both don’t need to be and in fact don’t seem so bright to us, even though they are actually delivering a greater amount of “useful” light. That perception is further bolstered by the fact that HIDs emit a lot of light in the green/yellow part of the spectrum which increases their perceived intensity to the human eye (unlike plants we favor light around the 550 nm mark). But the fact is that they are just wasting all this additional light since it is of little benefit to plant life.

If we take a 400w HID as an example, about 260 watts of that will actually be completely outside the Photosynthetically Available Range (PAR) so at least 65% of the light (and the energy used to produce it) is completely wasted. So with less than 40% of the light generated by HPS and MH lamps being absorbed by plants, and barely 10% of the electricity you pay to run them being actually converted into light in the first place this is not looking promising for conventional lighting (on these figure about 4% of the input energy ends up doing some good for the plant).

Some LED grow light systems do indeed include additional wavelengths, simply to enhance the visual appearance of the plants since foliage often looks black when lit purely by blue and red light. But there is no getting away from the fact that plants benefit enormously from the capability with LED lamps to smoothly vary the balance between blue and red exactly as needed. Seedlings do better with the balance in favor of blue light, while crop yields can be significantly boosted by switching over to red towards the end of the growing cycle. In this way you can simply replace MH lamps for early growth and HPS lamps used later in the cycle with a single, dynamically variable solution that reduces running costs and maintenance issues at the same time.

Why LED grow light can help for plant growth?

As we know, light is essential for most of plants’ photosynthesis. Without it, plants could not make food. But light can also be too intense, too hot, or last too long for growing healthy plants. In general, more light seems to be better. Plant growth accelerates with abundant light because more of the plant’s leaves have exposure; which means more photosynthesis.

One grower did an experiment two years before, he left two identical planters in the greenhouse for the winter. One was placed under a led grow light and one was not. By spring, the difference was astounding. The plants in the container under the led grow light were nearly 30% larger than those not receiving the additional light. Other than for those few months, the two containers have always been side by side. Years later it’s still evident which container was under the light. The container that did not get the added light is perfectly healthy, just smaller. With many plants, however, winter days are just not long enough. Many plants need 12 hours or more of light per day, some need as many as 18.

Adding led grow light to your greenhouse is an excellent option if you live in the North and don’t get many hours of winter daylight. LED Grow lights is an excellent option to replace some of the missing rays. Maybe you do not have an ideal southern location on your property for a greenhouse. Use led grow lights to supplement the day’s length as well as the quality and intensity of light. If your greenhouse covering does not diffuse sunlight well, you can add lights to fill in shadows for more even growth. Then you will find the amazing growing result by using led grow lights.

Why use grow light for greenhouse?

Some people might say: “I don’t like to live in a country where winter is a matter of a few chilly days and a few weeks of rain; where the sun is never far away, and the flowers bloom all year long?” But those greenhouse owner might say: ” I love it is sunny all day long and my flowers will get more stronger there than where temperature is below Zero degree.”

Greenhouses are wonderful structures that improve upon Mother Nature in a number of ways. Greenhouses warm the air and provide heat. They shelter plants from harsh winds, frost, and hail. Greenhouses protect from the sun’s burning rays and even from predatory critters. There are a few things a greenhouse can’t do. One is make days longer; at least not without the help of grow lights. Luckily new grow light technologies make lengthening the days easier than ever.

So far, many kinds of grow lights come out for greenhouse like HPS, MH, LED grow lights etc.More and more new grow light technologies are coming out for help your plants grow stronger and faster. The most advanced and energy-saving one is LED Grow Light which has been used for our traditional grow light replacement.

LED Grow Light Is used for home garden, greenhouse, farm where need artificial lights for the plants.Idea for all phase of plant growth, and work well with indoor garden, hydroponics, horticultural and soil base.

A proper lighting condition is the first and foremost important thing that plays an important role in the survival of most of the plants. Whether you decide to grow plants in soil or water (hydroponics), the proper amount of light is crucial to support healthy growth of plants and this is the reason that when it is not possible to provide enough light to indoor plants, most people rely on artificial lighting systems, known as indoor grow lights.

Being a great resource for indoor gardening, Indoor Grow Lights have gained popularity in the recent years where they have proved to be a boon for the people interesting in hydroponic indoor gardening. They promote plant growth by emitting an electromagnetic spectrum, much like a light spectrum to that of the sun to initiate the process of photosynthesis in the plants and thus allow indoor growth with outdoor conditions. There are spot grow bulbs, compact fluorescent bulbs, fluorescent fixtures, high pressure sodium, metal halide and LED grow lights to cater the needs of plants require different intensities of light.

Indoor grow lights have facilitated indoor gardening, especially in case of hydroponics where the plants are grown without soil. With the help of proper lighting system, it is now possible to grow marijuana indoors.  The time, when growing marijuana hydroponically indoors has become the preferred method to cultivate cannabis; the artificial lighting systems have become important pieces of equipment for those who want to take all the medicinal benefits of this most controversial drug. The medicinal uses of cannabis have always attracted people to cultivate marijuana but as each coin has two faces, there are many abuses associated with this drug. Unfortunately it is illegal to grow marijuana in many countries and this is the reason that indoor cultivation of drug has gained popularity in the recent years. are being one of the most crucial wholesale LED Grow Lights supplies, Indoor Plant Grow Lights have made it possible to grow most of the plants indoors.  Allowing year-round growing of the indoor plants, they truly have expanded the possibilities for all devoted gardeners where they can easily grow the plants they want to grow. With daily monitoring and maintenance, it is possible to achieve the optimal growth of your hydroponic garden and achieve the success in your mission to set up an indoor garden, where you can easily feel the beauty of nature.

proper hydroponics lighting

There has been a lot of press and hum lately about the new LED grow lights available from a number of manufacturers all over the world and web dealers. They have been promoted as the next generation of lighting for indoor hydroponics application. And perhaps one day they’ll be, but today is not that day. NASA is presently developing LED lights to be used on the space station. Because they use very little electricity they can be run off of batteries for long periods of time, so that food can be grown in space. Disney is using hydroponics with normal lighting to grow fresh goods to be used in their Florida theme parks. So development of hydroponic systems and LED applications is unquestionably on the way.

There are several benefits and downsides of using a LED grow lights. First we will rap about the advantages of using LED grow lights. To start with LED grow lights can last approximately from eight to ten years. A normal high pressure sodium or metal halide lamp will need to be replaced about once each year to once each year and a half. However against this LED lights can regularly last for at least 8 to 10 years with heavy use. LED lights use of little electricity and generate very little heat.

The problem with conventional high pressure sodium and metal halides lamps is they admit lots of spectrums that your plants simply do not need. For instance your plants really just need the red and the blue spectrum for the respective vegetative and flowering stage. You really have no need for lights in the other spectrums as it doesn’t do much to reinforce your plants rate of grow. One of the nice things about LED lights is that you can give your plants only the colors they need and not ones they do not. That’s why you’ll see most led lighting systems consisting primarily of red and blue lights. They’re able to save on electricity by only putting out high quantities of the bandwidth or correct range plants need for that stage of expansion.

Hydroponic Lighting and Grow Light Systems

Since most hydroponic gardens are indoors, they require artificial light which mimics the light of the sun for plants to be able to grow. Incandescent bulbs and light do not produce the right kind of light plants need to grow and flourish. The hydroponic garden requires full spectrum grow lights that imitate sunlight. Different hydroponic gardens will need specific lighting.

There is a wide variety of hydroponic lights available in the market and some better suited for some plants than others. Blue spectrum of light is best for hydroponic vegetables. Red orange light is best for hydroponic flowering plants and it can be gotten from led grow light.

The best type of hydroponic grow lights are those of blue spectrum, as it helps combat leggy nature of plants (as they train for light). The wattage selected depends on how big your garden is and reflectors can be used to supplement the lighting. These reflectors can be found in a hydroponic kit.

The best combination of lights for your hydroponic garden is that of blue and red orange light as it will keep plants compact and flowering. You can get a led grow lights that has both metal halide and the high pressure sodium bulb in the same lamp therefore no need of getting two lamps.

You can also purchase full spectrum light which has all the characteristics of natural sunlight. Fluorescent light is well suited for this purpose and it is usually used for growing seedlings but it can also grow the plants to full maturity. It is a simple and easy way of ensuring your hydroponic garden is well lit.

In the UK over half a million people actively use the hydroponic system of gardening. Taking advantage of this technology means anyone can produce plants, flowers, vegetables and herbs in their own home. It’s not only productive but sustainable, and for many people it’s a great pass-time or hobby. Buying hydroponic equipment has never been easier, with plenty of supplier to be found online with quick delivery across the country.
