Key things to Know before Buying the Cheapest LED Grow Lights Online 

What Is A Grow Light?

A grow light is a simple solution that adds a source of light to existing light especially in darker winter months. They provide specific temperatures and energy to the vegetation. They are only used indoors as simple lighting solutions.

Grow lights are also used for starting seedlings before the spring season. This ensures a healthy start to an outdoor garden. No matter what you are considering a grow light for, you can rest assured you will get the right one. Grow lights are popular with garden, well worth the investment, and give great results.

How Do Grow Lights Work?

Grow lights influence plant growth by providing spectral wavelengths. This light provides energy to the plants that support the chemical process of photosynthesis. Photosynthesis is the process that converts light into energy. The plant uses this energy to grow and produce.

Plants struggle for lack of nutrients due to lack of lights with many will look poor or not produce at all. If you plan on growing anything without the proper natural sunlight, you should consider a grow light.

Types Of Grow Lights – Cheapest LED Grow Lights Online 

To get the kind of light that meets your plant needs you need to pick the type of lights. The lights need to provide you the kind of spectral light that your plant requires. Before making a decision over the light you need, get to know your vegetation needs, the growth stages, and the light preferences. The type of lights includes:

  1. High-Intensity Discharge (HID). These bulbs produce a blue range of light providing support for early growth and maturity.
  2. Light Emitting Diode (LED). These are the most popular bulbs. They are small in size, cool usage, and able to customize panels to provide a fuller spectrum for plants to utilize. They are more affordable and found in many gardens.
  3. Plasma. They are like the HID bulbs but comes with a new technology that is efficient. It is very effective with cash crop production! It has a wide range of spectral light that supports any stage of growth.

What Light Spectrum Do Plants Use?

The light spectrum is the temperature wavelength. It comes from the colors that are both visible and invisible provided by the sunlight.

Plants prefer a certain range of wavelengths in the various stages of their growth. Grow lights are well able to provide the specific lighting needs for your plants.

Early growth and maturity plants prefer warmer, short wavelengths of light. These kinds of lights come in the bluer colored end of the spectrum.

What Light Spectrum Do Plants Use

Bloom and plant production needs cooler, long wavelengths of light. They come in the red end of the spectrum.

The differences in light preferences help define the sunlight that is a basic need for the plant throughout its growing time. Grow lights help you control what light your plant receives.

What should I consider when choosing the best and cheapest LED grow light?

LED grow lights have several advantages over other light sources, including high energy efficiency, long life, and high color rendering index (CRI). These grow lights are also significantly less expensive than the fluorescent and metal halide systems that they replace.

There are a lot of variables that influence the cost of a grow light. I would start by looking at the wattage of the bulbs, how many watts the lights require and how long they run on a full day (12 hours). Then I would look at the color spectrum of the bulb, the efficiency of the bulbs, and the cost of the bulbs. Here is what you will probably find, a single 100W HPS or HID will be cheaper than a full array of 400W LED's.
The most cost effective LED grow lights will always be those that produce a higher PAR (Photosynthetic Active Radiation) than the plants need. The amount of PAR required by a plant depends on the size of the plant and the temperature of the environment. The most common way to measure PAR is with an electronic PAR meter.

The best bang for your buck is usually going to be the brightest, cheapest LED that you can find. The main problem with LEDs is that they are not always energy efficient. 

The best LED grow light brands are the ones that offer the most bang for your buck. They must be able to provide all of the following features:

Good quality and durable products.

 The highest output per watt of energy.

The best warranty and customer support.

The most efficient products.

The best customer service, installation, and maintenance.

The most effective products.

What are the most common LED grow lights?

The most common and cheapest LED grow lights are made from CFL bulbs or compact fluorescent bulbs. These cheap grow lights are very good for small space growers, but their efficiency is not as good as high end grow lights. The average cost of these grow lights is about $30.

For many years, the most popular LED grow light for indoor plants has been the T5 (which is a 5-watt equivalent). This model has been around for a while and is relatively inexpensive. It’s easy to set up, and it’s also good for newbies because of its simplicity. However, this model is not very efficient at converting electricity into light. This means that it is not as energy-efficient as other grow lights.

If you’re on a budget and want to get the most out of your grow lights, it’s best to start with the cheapest models. They’re usually more efficient than their more expensive counterparts, which means that they use less energy. You can buy these grow lights from reputable sellers like Amazon, but you may need to do some research to find a reputable brand.
