LED grow lights have become very popular as an effective way to provide light to plants to help them grow. These lamps provide specific light and heat to the plants, promoting their growth.

How far should the LED grow lights be from the plants?

In general, you should try to keep your LED grow lights about 12 to 30 inches above the plants. Of course, the wattage of the lights, the type of LED lights, and how the plants are grown will all affect this distance. If you’re using a 600-watt or 800-watt bright light, you should make sure the plant’s leaves are about 25 to 30 inches away from it.

To determine the optimal distance for a plant to give it the best chance of healthy growth, you can use a “trick”.

Hand Test
Hold your hands under the LED Grow Lights at different heights — the heights your plants will be exposed to light. Hold your hand there for 30 seconds, if the heat is too much for you, you are too close. You want the LED grow lights to be close enough to provide heat to your plants without actually burning them.

Doing more research on the type of plants you have is highly recommended.

ECO Farm ECO D700 700W Samsung LM281B Chip LED Grow Light

Features:

This ECO Farm LED grow light features the highest output white chips and Osram chips, with a high energy efficiency of 2.6 umol/J, PPF 1820 µmol/s, LED grow lights provide plants with powerful and high-quality light to maximize yield . The vegetable footprint is 5 x 5 feet and the flowering footprint is 4 x 4 feet. This grow light has an excellent full spectrum (3000K, 5000K, 660nm, 730nm IR, 395nm UV) and is ideal for all growth stages (germination, cloning or cuttings, mothering, vegetative and flowering applications) for higher yields . The dimming knob can adjust the light intensity at will. Designed with daisy chain function, up to 100 lights can be connected. Multi-light connections with uniform dimming are especially beneficial for large-scale indoor and commercial cultivation.

Advance Spectrum 600W MAX LED Grow Light Bar

Features:

The 600W grow light panel will support all your indoor and outdoor plantation requirements. The LED grow light is dimmable to adjust the lighting and heat intensity according to the requirement. With a single knob at the back of the grow light fixture, you can take control over the intensity of the panel and take control of the power output for seedlings, flowers, and veg. The LED has blue, red, orange, and red diodes that create optimal light conditions for achieving a healthy yield. The 600W LED grow light equals 1000W HID power. The LED is highly efficient and increases chlorophyll molecule absorption. With LED lights, you can save approximately 80 to 90% of energy consumption. The diodes heat up less, so you do not have to worry about your plants getting damaged. Also, with less energy consumption, you save on power. The LED is rated at 50,000 hours, which ensures a long lifespan.

Features to Look for

When purchasing the best grow light, we recommend looking for the following features in a prospective model.

LED Lights
All modern grow lights feature design with LED technology. LED is effective and affordable to run. It’s the best way to give your plants the optimal spectrum they need for growth. LEDs have a longer service life than fluorescent, incandescent, or metal halide bulbs, and they use less electricity.

LED Output and Power
When selecting your ideal indoor grow light, we recommend looking at the LEDs’ output in your prospective light. The average small grow light for seedlings needs between 45-Watts to 80-Watts of light output. That’s enough lumens to help your plants achieve optimal growth.

LED Quality
The quality of the LEDs in your grow light makes an enormous difference in service life. The average high-quality T5 LED should provide you with at least 10,000-hours of service life before replacement.

Light Spectrum
It’s critical that you look at the wavelength emitted by the device when purchasing your grow light. Plants require full-spectrum light for the best growing results. Look for models featuring a full PAR spectrum, offering both red and blue wavelengths. Some models will also feature white-light.

Lighting Modes
Your LED grow light should feature different lighting modes. Look for models offering blue, red, and full-spectrum modes for your choice of growing conditions. The lighting modes affect your plants and how they grow.

PAR refers to the balance of red, blue, and white light in your LEDs. Top models feature high PAR ratings, giving you the best performance out of your new grow light.

Timers
The best grow light for seedlings come with timers. You get the option of setting your light cycle to 3-hours, 6-hours, or 12-hours, depending on your plant’s needs.

A timer is a handy feature in your light, allowing you to control the light cycle. However, if your model doesn’t come with a timer, you’ll have to purchase one separately or rely on manual operation.

Conclusion

LED grow lights are not just ordinary lights. The reason why they are so useful for indoor growing is that they provide the infrared and ultraviolet radiation that plants need.

Virtually every grower will confirm to you how important LED lighting is to plant growth and flowering.

So yes, LEDs are actually good for plants.
