Common Kinds of Hydroponic Lighting

Sunday, August 1st, 2010

philips biotower Common Kinds of Hydroponic LightingIn hydroponics, one of several largest contributing factors to plant development (other than the nutrient remedy) may be the lighting. Crops require light in order to conduct photosynthesis, plus they require distinct wavelengths in the lighting spectrum for various stages associated with maturation (plant growth and browsing works on the diverse the main range than blooming and flowering). Hydroponic lights (generally called “grow lights”) are utilized to stimulate these kinds of conducts in crops. Here are the most typical forms of hydroponic lighting, and also their particular use.

Metallic Halide (MH)

One of the most widespread forms of develop lights, this can be a High Intensity Release (HID) bulb which leans in the direction of the blue perhaps the range, that stimulates grow vegetation and also leafy growth. If your lawn doesn’t have organic lighting at all, this is a good option for the primary lighting supply. Plants produced under MH lighting usually are thick and small.

High Pressure Sodium (HPS)

Furthermore a great HID, this kind of bulb handles the particular lemon and red range bands, that will work for the blooming and also budding phase. This kind of bulb is best utilized as additional lights, either along with organic sunlight or even with a different type of light bulb, like MH. Crops grown purely under HPS lighting often shoot up rapidly, producing abnormally slim and also tall crops.

Fluorescent lighting

Utilized because grow lights, standard fluorescent light bulbs tend to be great for seedlings and sometimes lettuce and spinach crops, however in most cases these people do not have sufficient intensity to give other crops the actual illumination they require. However, the more recent high-output fluorescent make great hydroponic lights, because they could be combined to cover the full lighting range. Also, these people give off much lower warmth than their own HID counterparts, to allow them to be placed much nearer to the crops with much better outcomes.

LED lighting

One of several newer options available, LED develop lighting is applauded as a great choice within hydroponics simply because they can include a simple spectrum also, since they emit intense light with very little heat. The the disadvantage is that that they can be quite costly, and many growers have motivated that they can obtain every bit as good of your color distributed from fluorescent or various other less-expensive permutations. So while LED lighting can do a fantastic work and are not at all hard, the court is still out concerning their cost-effectiveness.

Incandescent grow lights

Incandescent light bulbs, even though commonly accessible, are seen as the least effective choice within hydroponic illumination. These people give off a limited colour range and also burn therefore warm that they cannot be placed close to sufficient towards the crops to become very effective. Color-corrected incandescent are sometimes used as highlight lighting in order to health supplement additional illumination for person plants, however incandescent should not be harnessed for the major illumination supply.

Because hydroponic lights handle some part on the spectrum necessary at different phases of development, many gardening purposes will use multiple form of light bulb within their lighting effects array to deliver full coverage. Because different plants possess distinct wants, what you grow will determine how your lighting should be arranged.

Selecting the Right Kind of Grow Light

Thursday, July 8th, 2010

grow lights LED 08 Selecting the Right Kind of Grow Light Natural lighting is not the only source of illumination in hydroponic gardens because some gardens use a mix of natural and synthetic light and some even use artificial lighting completely. Plants utilize different parts of the light spectrum at different stages of growth. The lights used in hydroponics are called “grow lights“, properly named because they are designed to produce light that make plants grow! Because artificial lights cannot cover the full spectrum that natural sunlight can, it’s important to use the right kind of grow light for the kinds of plants you’re raising, and it’s important that the correct lighting be used at the right period of growth. In order to make it easier for you to choose the right type of grow lights, here are some useful details.

For crops that are on the early stages of growth along with leafy plants, the ideal grow lights are those lights that fall within the blue-white color spectrum. To supply this kind of ligth for your crops then you might want to try and utilize the Metal Halide or MH bulbs. These bulbs can burn hot but doesn’t require close proximity to the plants in order to provide adequate ligthing, these bulbs are otherwise known as High Intensity Dishcharge bulb or HID. Plants that are subjected to the MH bulbs have the tendency to grow thick, leafy, and small. MH bulbs are used as the primary lighting supply in numerous gardens.

During the blooming stage, plants draw more from the orange-red side of the spectrum. High Pressure Sodium bulbs (HPS), a different kind of HID grow light, are very good at this stage of plant growth. HPS bulbs are not a fine choice as a main light source because of their limited spectrum, but these bulbs are perfect as additional lights to other types of lighting source. Without supplemental lighting your crops may develop unnaturally long and thin.

If you are mainly growing seedlings (or if you have a separate area for the seedling stage of plants), a fantastic choice is standard fluorescent lighting, positioned close to the seedlings. Standard fluorescents cover a decent part of the light spectrum while giving out a low intensity-a near perfect condition for seedlings. You do not have to worry about burning the seedlings because these lights emit low heat. Nevertheless, in different conditions the use of low intensity standard fluorescent bulbs may not be beneficial and may not help in the growth of the plants.

A blend of different grow lights are often used in different hydroponic gardens, but if money is an issue then you can usually use a high-output fluorescent lights as grow lights. In contrast to standard fluorescent grow lights, the high-output bulbs offer a more intense light with low heat, and can be arrayed to cover almost the entire spectrum of natural light. These bulbs may not be as intense as HID bulbs but these high-output bulbs are more affordable and because it produces little or low heat you can place these bulbs close to the plants and make up for the low intensity and the results are still excellent.

Choosing the right kind of grow light for your hydroponic garden can be intimidating, but knowing how different types of light help your plants grow will help you pick the right grow lights for your garden.

Popular Varieties Of Hydroponic Lights

Wednesday, July 7th, 2010

hydroponics10 300x300 Popular Varieties Of Hydroponic LightsThe biggest contributor to plant growth in hydroponics, with the exemption of the nutrient formula is the lighting or the lights. Lights with particular frequencies in the light spectrum are utilized in every stage of plant growth, this process is called photosynthesis and for plants to conduct this process they will need sufficient amounts of light. Grow lights or hydroponic lights are used in order to initiate this process in plants grown in hydroponic gardens. Here is a brief list of the different kinds of hydroponic lights and how each is used.

Metal Halide (MH)

High Intensity Discharge or HID bulb is the most common variety of grow lights that makes the plants prosper and the leaves to grow due to its affinity to the blue side of the light spectrum. If your garden has no natural lighting at all, this is a good option for your primary lighting source. Plants cultivated under MH lighting tend to be thick and tight.

High Pressure Sodium (HPS)

Additionally an HID, this bulb covers the orange and red spectrum bands, which is excellent for the flowering and budding phase. This bulb is best utilized as supplementary lighting, either with natural sunlight or with another type of bulb, like MH. Plants cultivated strictly under HPS lighting tend to shoot up quickly, producing abnormally thin and tall plants.

Fluorescent lights

Used as grow lights, standard fluorescent bulbs are good for seedlings and sometimes lettuce and spinach plants, but in most cases they do not have enough intensity to give other plants the lighting they need. Nonetheless, the more contemporary high-output fluorescent lights can function well as hydroponic lights because when mixed these lights can give off a full light spectrum. Since these bulbs do not give off as much heat as the HID bulbs, you can position these bulbs in close proximity to the plants.

LED lights

One of the more recent choices available, LED grow lights are touted as a great choice in hydroponics because they can cover a broad spectrum and because they emit intense light with very little heat. The down side is that they can be quite expensive, and many growers have determined that they can get just as good of a color spread from fluorescents or other less-expensive combinations. So while LED lighting can do a great job and are fairly simple, the jury is still out as to their cost-efficiency.

Incandescent grow lights

Despite the availability and the price, incandescent bulbs are still the last on the list when it comes to the different options of hydroponic lights because it is least productive. They emit a limited color range and burn so hot that they cannot be placed near enough to the plants to be very effective. Nevertheless, you can use color-corrected incandescents as accent or supplementary lighting, but using these bulbs as primary lighting is a big no-no.

Because hydroponic lights cover various parts of the spectrum required at different stages of growth, many gardens will use more than one type of bulb in their lighting array to provide full coverage. Because diverse plants have different needs, what you grow will establish how your lighting should be organised.
