Best LED Grow Lights 4ft for Indoor Plant?

2021-10-15

When it comes to investing smartly in your indoor grow, nothing can beat the most sustainable option – LED Grow Lights. LEDs are not just great for the health of your indoor plants but also give your nursery or an indoor grow a completely vibrant look at a cost-effective price. But with so many options available in the market ranging from small size to large commercial LED grow lights, it isn’t easy to choose the best LED grow light for the money that perfectly matches your requirements.

Worry not! We have curated the top suggestions based on people's requirements, budget options, bestselling reviews, and functions to let you get the right led grow light for indoor growing. But before heading to the list, lets learn a little more about the working and benefits of these lights to make the right decision.

What is an LED Grow Light?

LED (light-emitting diode) Grow Light is a kind of energy-efficient artificial light used to enhance the natural growth of indoor plants by providing them an adequate amount of lighting. Most of the LED bulbs produce light waves of Blue and Red color, responsible for the plants’ growth. Red light waves respond to the Phytochromes (responsible for leafy growth), while blue light enhances the photosynthesis process and stimulates stronger roots. Depending upon the plant type, you either require red or blue or both light waves for healthy plant growth.

How do LED Grow Lights Work?

Unlike other fluorescent bulbs or lights, LED grow lights use two different kinds of semiconductors: Electrons (carry a negative charge) and Holes (have a positive charge) to create their own light spectrum. This light spectrum act as a supplement to natural light and helps plants grow healthier and faster.

While the other bulbs or lights use filament or mercury or lead to produce light, LED grow lights use their semiconductor chips to emit the light spectrum and thus more energy-efficient, eco-friendly & long-lasting.

Why Choose Full Spectrum LED Grow Lights?

Different LED Grow lights emit different wavelengths depending upon their spectrum pattern. These different light wavelengths stimulate different stages of plant growth, and thus while choosing the correct grow light, you must check its spectrum according to the sort of stimulation you want. For example, LED that is perfect for vegetation might not be as effective with flower development.
But Full Spectrum LED Grow Light caters the plant stimulation at different stages according to your need, and thus you can use it for all. Full-spectrum grows light is an adjustable LED light that emits lights of different wavelengths similar to the Sun. In other words, Full Spectrum Light emits all wavelengths of light that are emitted from the sun.

Many plants not only require red or blue light but all the colors of visible light (even in a limited amount) for proper growth. For such plants, Full-Spectrum light is the best suitable option. For example, the Cannabis plant requires different lights of different wavelengths at its various growth stages, and thus it is advisable to use full-spectrum light for its healthy growth.

What Are PAR Values?

Plants use a specific light range known as Photosynthetically Active Radiation (PAR) for photosynthesis. The PAR values involve the electromagnetic wavelengths between 400 and 700 nanometers on which different stages of plant growth occur. Grow LED lights produce a ton of lights of different wavelengths but are not absorbed by plants. Plants only absorbed lights of some specific wavelengths, and they reflect rest. So, in simple words, PAR is the light’s amount that is usable to plants.

The effectivity of any Grow LED light depends upon its PAR value. It is measured by the number of micromoles of light per square meter per second. The more intense the PAR value of the LED light, the more effective it will be. So, always check the PAR value of grow light while opting for the right one for your indoor garden.
600–1000 µmol/m²/s: High-strength light. This range is best for developing growth and flowering.
400–600 µmol/m²/s: Medium strength light. Suitable for early veg and stretching.
200–400 µmol/m²/s: Low strength light. Ideal for delicate seedlings and clones.

What is PPFD Value and its significance?

Just like PAR, PPFD Value also plays a crucial role in determining the efficiency of a grow LED light. PPFD stands for “Photosynthetic Photon Flux Density.” 

PPFD is basically the measure of LIght intensity, and it tells how much many light photons that fall within the PAR range hit a given square meter per second (in micromoles). PPFD value doesn’t tell you how much measured light will land on plants, but it is still crucial to determine the efficiency of a particular grow light. The longer will be your light cycle, the lower will be optimal PPFD value and vice-versa.

What are the Benefits of Using LED Grow Lights?

LED Grow Lights are way better than the conventional HPS lights in terms of:

1) Economical: LED grow lights use less energy and heat to produce more usable light and thus a much economical and convenient option than traditional lights, which cost you long electricity bills.

2) Eco-Friendly: Since LED lights don’t contain toxic gases or substances such as mercury or lead, they are eco-friendly and recyclable.

3) Longer Lifespan: LED lights use less temperature to produce more heat, making them more sustainable. They are designed to last longer for up to 102,000 hours. Their low operatable temperature makes them long-lasting and more durable than conventional lights.

4) Efficiency: LED lights convert energy into usable light 40-60% more than conventional lights with a low heat signature. While the other traditional lights given off most of their energy as heat and only efficient 20-40%, LED grow lights produce very light heat and utilize most of their power into light emission.

5) Less Heat Production: Unlike HID lights, LED grow lights rarely emit wavelengths of 730nm, due to which only a minimal amount of heat is directed towards the plants, and the rest is the ambient heat from the panel. This makes grow lights suitable for plant growth as more heat production can burn the leaves of the plants and damage their development.

6) Better Crop Production: One of the best advantages of grow lights is that they speed up the growth process of plants by providing adequate lighting just like natural sunlight, resulting in better crop production.
