FAQ

There are many benefits to using LED grow lights over more traditional HPS lighting. Here are some of the most common questions we receive from people who are looking to learn about LED grow lights!

• How and when should I use LED Bar Lights?
  ROHE's lamp strips are IP65 rated and can be used in a variety of ways.
• What is the recommend Bar Light hanging height?
  ROHE recommends keeping a distance of 12" between your Bar Light and the top of your canopy. Work for all primary lighting applications that deal with average light use plants such as leafy greens.
• Will any LED light work as a grow light?
  Not all LED lights are suitable for use as plant growth lights. Consideration needs to be given to spectrum, intensity, energy efficiency, cooling and heat dissipation, light duration and photoperiod, type of plant also have an impact.
• What is the best LED light to grow with?
  Understand the importance of the spectrum, wattage and intensity, PAR (photosynthetically active radiation), cooling mechanism of LED lights,
• Are LED grow lights better than sunlight?
  In recent years, technological advances have revolutionized the way we live in every aspect of our lives, including agriculture. LED (light emitting diode) plant growth lights have become an innovative solution for indoor plant cultivation, challenging the traditional reliance on natural sunlight.
• What type of light is best for growing plants indoors?
  The importance of Light to houseplants Light is an essential element of photosynthesis, the process by which plants convert light into chemical energy to fuel their growth.
  Fluorescent lamps: Fluorescent tubes are a popular choice for indoor gardening due to their affordability and availability. They have different spectra, with cold white light and daylight bulbs best suited for plant growth.
  LED lights: Light emitting diodes (leds) have a wide spectral range due to their versatility and efficiency and can be customized to the specific needs of different plants at different growth stages.
• What color LED grow light is best?
  Blue light (400-500 nm) : Blue light is essential during the vegetative phase of plant growth. It promotes strong root development, compact leaves and overall solid plant structure. This wavelength also helps regulate the plant's photoreceptors, enabling efficient photosynthesis.
  Red light (600-700 nm) : Red light is essential during the flowering and fruiting phases of plant growth. It plays a key role in stimulating flowering hormones and increasing flower and fruit production. Red light promotes elongation of the stem and affects the overall size and quality of the yield.
  Full spectrum light: Full spectrum LED grow lights attempt to mimic natural sunlight by providing a balanced combination of blue, red, and other wavelengths. This type of light is suitable for the entire life cycle of the plant from germination to harvest. While it may not be as professional as using separate blue and red lights, it offers convenience and versatility.
• How far should LED grow lights be from plants?
  Seedlings and cuttings: Place LED grow lights 24 to 36 inches (60 to 90 cm) above seedlings and cuttings to prevent overstretching and ensure healthy growth.
  Vegetative stage: During the vegetative growth stage, the lamp is placed approximately 18 to 24 inches (45-60 cm) from the plant canopy to promote robust plant growth.
  Flowering and fruiting stage: When the plant enters the flowering and fruiting stage, move the lights closer to a range of 12 to 18 inches (30 to 45 cm) to provide the bright light needed for optimal bud and fruit development.
• What is the best time of day to use a grow light?
  In the morning, when the sun rises to energize the world, plants benefit from the early start of the grow light, which can be turned on early to kick-start the plant's metabolic process.
  Afternoon glow: Midday surge As the day progresses, sunlight intensity peaks at midday, during which harnessing the power of plant grow lights can bring significant growth results.
  Just as the sunset provides a soothing transition into the night, the proper use of a grow light can help ease your plants into their resting period.
• Are full spectrum LED lights good for growing plants?
  Full-spectrum LED (light-emitting diode) lamps have become a strong contender in the search for optimal plant growth, aiming to emit a balanced spectrum close to natural sunlight, providing plants with the full spectrum needed for photosynthesis. The role of Light in plant growth Plants primarily use light for photosynthesis - the process of converting light into chemical energy to promote their growth
• Does full spectrum LED grow light have UV?
  Full-spectrum LED (light-emitting diode) lamps aim to replicate natural sunlight, emit light in a variety of wavelengths covering the entire spectrum (from ultraviolet to infrared), and are essential for photosynthesis, the process by which plants convert light energy into chemical energy to fuel their growth. Different wavelengths and plant growth Different wavelengths of light play different roles in plant growth.
• Is full spectrum light the same as LED?
  Full spectrum light and LED Full spectrum light refers to light that contains multiple wavelengths, simulates natural sunlight, and includes all colors of the visible spectrum as well as parts of the ultraviolet and infrared spectra. Full-spectrum light sources are designed to replicate this natural balance of wavelengths to create an environment similar to natural daylight.
• What is the most powerful LED grow light on the market?
  Powerful X² commercial LED plant growth lights In agriculture and horticulture, the development of technology helps to advance planting practices. An innovation sweeping the industry is the X² commercial LED plant growth Lamp, a cutting-edge product from renowned manufacturer ROHE. ROHE's X² commercial LED plant growth lamps have received attention and acclaim for their impressive power and indoor and greenhouse cultivation performance.
• What color LED light is best for plant growth?
  Blue light (400-500 nm) : Blue light promotes vegetative growth, compact leaves and strong root development. It is essential for regulating plant stature and overall plant development. Blue light promotes the synthesis of chlorophyll, which is an integral part of photosynthesis.
  Red light (600-700 nm) : Red light is essential for flowering and fruiting. It triggers photoallergens, which promote the flowering response of long-day plants. Red light is also essential for overall growth and energy accumulation.
  Far-red light (700-800 nm) : Far-red light plays a role in plant responses related to germination and flowering. It can affect the timing of flowering in certain plants and affect the "shade avoidance" response, which is when plants stretch out to get more light.
  Green light (500-600 nm) : Green light is not effectively absorbed by chlorophyll and is often reflected, which is why plants appear green to our eyes.
• Is it better to leave grow lights on all the time?
  Different plants have evolved to thrive in specific photoperiods that affect their growth patterns, flowering and even fruit, so the amount of daylight needs to be determined based on the type of plant characteristics.
• Can I leave LED grow lights on all night?
  Different plants need different sunlight at different stages, and excessive irradiation may affect the growth, flowering and fruiting process of plants.
