ECO Farm ECOL 90W LED Grow Light Bar VS Mammoth Lighting 100W Single Bar

Most people are worried about whether their tender plants are getting enough natural light during this approaching winter. If that's the case and those who are considering gardening indoor, this article about led grow light strips will be helpful.

Getting sufficient light for their plants is always a concern for gardeners during winter because there isn't enough natural sunlight during these times, and plants can't be exposed to the severe cold outside. No way, not by any stretch of the imagination.

So, to offer the solution to this concern, the grow lights have come up with some unique features. No matter what plants an individual is growing in an indoor firm, these lights offer the perfect replacement for natural lights and are suitable for all kinds of indoor farming.

What are Grow Lights?

The plant grow lights are the artificial light source that is used to initiate and stimulate plant growth and provide the spectrum of light that is necessary to start the process of photosynthesis in plants that are either deprived of direct sunlight or no light source exists at all. They are generally electrically powered and are used to provide the spectrum of the light that is similar to the sun in conditions where the day lengths are short and plants are unable to receive the number of lights required for their optimum growth. Depending on the nature of the plants being grown, grow lights can be adjusted to meet their requirements of temperature, intensity, wavelength, and distance according to the growth stages such as germination, flowering, vegetative growth, and buds or fruit formation till maturity of the plants to the final harvests.

What are LED Grow Light Strips?

LED grow light strips are basically smaller variants of a proper LED grow light panel. These are strips of light that offer lesser lighting in comparison but offer a more angular lighting solution. These are generally not used in isolation but along with an LED grow light. The thing about grow light panels is that they are too big to be placed anywhere other than the top of the grow tent. However, that means that portions of the plant which are on top get better lighting and as the plant grows denser, the lower areas get lesser lighting. Hence, LED strips can be used to help the plants grow in a better manner and provide lighting to areas where light would otherwise not reach properly.

Buyer's Guide: Things to Look For Before You Buy LED Grow Light Strips

One must remember that these light strips are never the primary source of light but act as a secondary source of light to areas where the primary source cannot properly reach.

This is particularly beneficial for those growers who are growing a large number of plants. If you are a grower who is growing on a small and personal scale you might skip it. 

This will benefit those growers who have a very thick foliage layer on the top portion of their plants. If your grow light isn't able to reach the bottom portions you might want to use these light strips to enhance that area.

Another type of growers that this light is for those who are using low intensity grow light panels and want to ensure an extra dose of brightness.

Size
While determining a grow light size, consider the number of plants one wants them to cover. Likewise, if someone wants to move the lights around, they will require something light and compact. Space is another essential thing to consider. One should ensure that they have enough space for operating these lights, and any furniture, wraps, or different things don't hinder them.

Type
Numerous kinds of grow lights are available in the market. Some of them include the overhead hangs, panels, or screwing into a conventional light apparatus. It's upon the user to decide what to choose. The plant types, the amount of natural light existing, and the plants' location will help in the decision-making.

Convenience
From installation to keeping them working appropriately, a few lights need more effort than the rest. Also, don't forget about the noise factor, especially if it will be set in a bustling place.

Wattage
To determine the right wattage of the light strips one wants to buy, it's important to think about the size of the growing room and plants. If a grow room is little with just a few plants, a light that has a minimum wattage is good enough.

On the contrary, a bigger grow room will need more powerful lights and hence more light strips.

Light Spectrum
The light spectrum is the light frequency that a plant will need at different growth stages. Though it's easy to grow a plant utilizing simply blue or red light, most plants grow relatively quicker with a more extensive spectrum of light.

Using a blue light along with red light can be an ideal mixture. One can use red light alongside blue light to build photosynthesis, size of plants, leaf number, size, chlorophyll content, etc. However, using either blue or red light singly might delay the development process.

Low Heat Emanation
Excess heat generation can excessively damage the tender plants due to burning problems. If faster growth of plants is what's required, one should choose only those lights that are known for durability and safeguard the plants from burning.

A grow light stays near the plant's foliage while the lights generating excess heat are inclined to burn the plants when sitting's lit-up for a few hours during a day. Therefore, one must be careful enough to choose a light that generates minimal or balanced heat.

Material Quality
No way it's possible to determine a material's quality without using it. Some items have different capabilities and costs, yet one might not be sure about their quality. Always check the brand reputation, opinions of the past users, and organization's portfolio for their business history.

Its recommended buying the product only after being satisfied with the item and services offered by the provider.

Energy-savings
The grow lights will be supposed to be lit up for, say, twelve to fourteen hours, or even more depending upon the type of plant grown. Therefore, one must know the wattage, and the everyday light consumption the chosen lights will burn through.

Choose the energy-saving option that won't increment the expense for building the specific plants, mainly for those who are a hobbyist and shouldn't grow for commercial purposes.

Lifespan
LED lights should usable for the years under the standard conditions in the grow room. Check for the most maximum reasonable assurance/guarantee that comprises of years with the replacement alternatives. DO NOT sacrifice quality over low prices as it would hurt over the future.

Conclusion
So, whenever deciding to buy the best grow lights in the future, it's important to consider the essential aspects like full-spectrum lights, less heat generation, less power consumption, convenience, easy installation, etc.
More or less, all the products mentioned above offer these features. However, to determine what exactly the necessity for an indoor garden is, it is recommended to do thorough research and then choose the ideal product for a nursery/garden, etc whatever it is.
