PAR, which stands for Photosynthetically Active Radiation, is the type of light that plants use to carry out photosynthesis, the process they use to make their food. This light falls within a specific range of wavelengths that are visible to us, ranging from blue to red colors. So, when we talk about PAR, we’re referring to the light that is essential for plants to grow. It’s like the energy source that powers their growth.

When we measure PAR, we’re essentially gauging how much of this vital light is available to plants in a given area at a specific time. This measurement helps us understand how effective a light source, such as an LED grow light, is in supporting plant growth.

PPF stands for “Photosynthetic Photon Flux.” It’s a measure of the total amount of light, specifically within the photosynthetically active radiation (PAR) range, that a light source emits per second. In simpler terms, PPF tells us how much light energy a light source produces that plants can use for photosynthesis. It’s typically measured in micromoles per second (μmol/s).

PPFD stands for “Photosynthetic Photon Flux Density.” It measures the amount of photosynthetically active radiation (PAR) that reaches a specific area on a plant’s surface per second. In essence, PPFD tells us how intense the light is at a particular point where the plants are growing. It’s usually measured in micromoles per square meter per second (μmol/m²/s).

PPFD is crucial for understanding how much usable light is available to plants in a given area and is an essential factor when designing lighting setups for indoor gardening or plant growth, as it directly influences plant growth rates and overall health.

BTU stands for British Thermal Unit, which is a unit of measurement for energy. It represents the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit.

The number of LED grow lights you need depends on factors like the size of your growing area, the type of plants, and their light requirements. For a 10-square-foot space, start with 2 of our 4×8 or 4x10ft grow lights and adjust based on how well your plants are responding.

An IP rating, short for Ingress Protection rating, tells you how well a device is protected against dust and water. It’s usually written as “IP” followed by two numbers. The first number rates protection against solids, like dust, while the second rates protection against liquids, like water. If a fixture is IP65 rating, that means it can be submersed in water. Actually, led grow lights is no need of IP65, because it won’t submersed in water, only some spray. So IP54 is enough, and most cost-effective.

Blue light promotes vegetative growth, while red light stimulates flowering and fruiting. A combination of both spectra, along with some green and yellow wavelengths, can support overall plant health and development.

For flowering, red light spectrum is best as it encourages blooming and fruiting. For vegetative growth, blue light spectrum is ideal as it stimulates leaf and stem growth. However, a balance of both spectrums is often recommended for overall plant health and optimal growth throughout different stages.

“Full spectrum” describes lighting that emits a wide range of colors similar to natural sunlight. It covers all colors from blue to red, plus wavelengths beyond what we can see. This type of lighting is great for plants because it mimics sunlight, offering the diverse light they need for healthy growth and photosynthesis. All Maksdep led grow lights are of full spectrum. Please feel free to contact us for spectrum report.

Both spectrum and light intensity are important to plant growth, but they serve different purposes. Spectrum influences plant processes like photosynthesis and flowering, while light intensity affects how much energy plants receive for growth. A balance of both spectrum and light intensity is crucial for optimal plant growth and development. Contact us with your growing conditions, we recommend the suitable lights for you. Maksdep are a professional led grow light supplier, offering full spectrum led grow light from 100w to 1600w.

Proper UV can be beneficial for plants, too much exposure can be harmful to both plants and humans who work in greenhouse. It’s important to strike a balance and ensure that plants receive enough UV for growth without risking damage to workers or plant health. Contact us to get the best solutions.

LED, HPS, and MH are different types of lighting commonly used for plant growth. LED lights are energy-efficient and usually full spectrum suitable for various growth stages.  Unit price is high, but it’s with long lifespan and almost no maintain cost. It’s friendly for long-term using.

We have many kinds or grow lights of different size and coverages. 2x2ft, 2x4ft, 3x3ft, 4x4ft, 5x5ft, 6x6ft, 4x6ft, 4x8ft, 4x10ft grow lights available. Max coverage is 6x12ft.

Generally speaking, the higher the efficacy of a grow light, the better. A grow light of higher efficacy will result in cost savings on electricity bills and potentially better plant growth. However, other factors such as light spectrum and coverage are also important to consider for optimal plant growth.

Passive cooling relies on natural methods like heat sinks or air vents to dissipate heat, while active cooling uses fans, liquid cooling systems, or other mechanisms to actively remove heat from the source. Passive cooling is quieter, active cooling usually require more power and maintenance.

LED grow lights offer several advantages over other types of plant lights, energy-efficient, full spectrum, long lifespan and less maintenance.

No, LED grow lights may have a higher upfront cost, but it’s cost effective for long term use. And with the development of led technology, leds are cheaper now. Our 720w led grow lights are only cost $85usd. long lifespn and energy saving, less maintenanice. It’s much better than traditional HPS and MH lights. A choice for indoor plant cultivation.

Different plants needs different amount of light to thrive. Generally, most plants need around 6 to 8 hours of sunlight each day for healthy growth. We can use DLI to calculate how much light need. Daily Light Integral (DLI), which quantifies the total amount of photosynthetically active radiation received by plants in a day. Understanding and meeting the DLI requirements of specific plants is crucial for ensuring optimal growth, flowering, and yield.

The number of lights should use depends on your growing area size, the type of plants, and which grow lights will you use. Contact us with your situation, our professionals will reply you with professional solutions.

The height depends on the type of light and plants, and plant growth stage. As a general rule of thumb, hang LED grow lights about 12 to 24 inches above plants during the vegetative stage, and closer, around 6 to 12 inches. Contact us for professional advice.

It depends on the type of lights and plants, and your plants growth stage. In general, most plants benefit from around 12 to 20 hours of light per day during the vegetative stage, and 8 to 14 hours per day during the flowering stage.

Led grow lights need less maintainence. It’s better not run 24hour/day, day and day. Give them some time to rest, 3-5 hours per day. And operate as instruction. Any issue met, please feel free to contact us, we will reply you with solution within 24 hours.
