How To Choose The Best LED Grow Lights

Finding the best LED grow lights is the way to get the most out of your indoor gardening efforts.  But do you know what you should be looking for?  Do you know what makes for the best LED grow lights?  If not, then here are the things you need to know about LED grow lights.
The first thing you need to know about is what color light you need.  Many people when they think of grow lights think any bulb that claims that it mimics sunlight would be best.  And they would be wrong.  Plants use two parts of the spectrum, rather than the whole of it.  To power photosynthesis and create food, they need some of the red-orange part of the spectrum.  And for reproduction, they use blue-violet.

Conventional grow lights produce a full spectrum of light and waste energy doing so.  They also produce a lot of heat.  The heat that they produce tends to dry the plants out that they are helping to grow and require two things as a result.  They need a cooling system, which must be purchased separately, and the plants require more water to counteract the drying from the lights.  Both of these consequences result in additional operating expense.

LED grow lights produce less heat and it is made in the base where it is harmless to the plants.  They come with built in cooling fans, so there is no additional expense.

LED grow lights can now be designed to produce exactly the light frequencies that are best used by plants.  And that’s one of the first things to look for when choosing the best LED grow lights to benefit your indoor garden.  Make sure that they are emitting the right colors as stated above.  Not all of them do, so do your research.

The next important feature to look for is the power or wattage of the lights.  This is critical.  Many grow lights are sold that are so underpowered as ton be useless.  You must look for LED grow lights in which each constituent LED has an output of 1 watt.  There are plenty of cheap LED grow lights on the market with outputs in the area of 0.06 watts from each LED.  These are almost useless and will only result in disappointment.

Choosing the best LED grow lights with the right output in terms of wattage and color of light emitted will give you the results you want from your indoor garden.  Your plants will grow faster and more fully in less time.

A Guide To The Three Most Used Grow Light Technologies

Buying a grow light or grow light system is not always a straightforward decision.  The best technology will depend on the type of plant that is being grown and its development stage.  For example some lights are better able to promote flowering while others encourage fast growth and sprouting.  In this article we provide insight into the three main types of grow light that are used by indoor gardeners to start you on a process of determining which is most suitable for your grow lighting needs.

For grow light gardeners looking for a cost effective, energy efficient and environmentally friendly grow light technology, LED grow lights tend to rise to the top of the list.  They have a longer lifespan than other grow light technologies, use less energy and emit less heat.  Cooling systems, heat extraction fans and high voltage ballasts are generally not needed.  LED lights can be placed in close proximity to the growing plants or seedlings with little risk of scorching or dehydration.

The standard fluorescent bulbs used for many years by grow light gardeners are slowly being replaced by higher output fluorescent bulbs and hybrid fluorescent/HID systems.  While these are more expensive than the standard bulbs they produce a light that is more direct and concentrated via the use of special reflectors.  Reds, Whites and Blues are available.

High Pressure Sodium (HPS) and Metal Halide (MH) are the most common types of Higher Intensity Grow Light (or HID grow light) used for grow light gardening.  Mercury vapor lights are also used but less often.  While HID light do not last as long as LED grow lights for example and are more expensive to run, they produce a very intense light.  HPS and MH lights are often used in combination to ensure all required wavelengths of light needed for maximum absorption are produced.
