Ready to optimise your indoor garden? The HortiONE 420 LED Panel has got you covered.

The HortiONE 420 LED is an advanced lighting solution designed specifically for indoor hydroponic cultivation. This innovative product offers an exceptional balance of efficiency, durability, and performance. Here’s how it works and why it stands out from other grow lights.

Advanced LED Panel Design

The HortiONE 420 features a 45° angled LED panel. This unique design enhances light diffusion and ensures even coverage throughout your grow area. The reflector supports diffuse lighting, increasing homogeneity and higher light output. Consequently, your plants receive optimal light exposure, promoting uniform growth.

Hybrid Construction

This LED panel uses a combination of high-quality components. It integrates full-spectrum MID-Power LEDs (Seoul 3030C with 4000K) and OSRAM giant high-power LEDs (deep-red: 660nm). This hybrid construction provides a balanced light spectrum suitable for both vegetative and flowering phases. As a result, you can expect healthy growth and excellent flowering results.

Full-spectrum and High Efficiency

The HortiONE 420 LED delivers a high light output with an efficiency of 2.9 µmol/J. This feature means for every watt consumed, you get more usable light (PPF), ensuring your plants get the best light possible. The full-spectrum lighting mimics natural sunlight, promoting natural plant development and true colour rendering.

Enhanced Durability and Longevity

Designed for long-term use, the HortiONE 420 is highly durable and resistant to volatile organic compounds (VOCs) and sulfur. With a lifespan of over 50,000 hours, this grow light is a reliable investment for serious hydroponic gardeners. It’s able to withstand the challenging conditions of indoor cultivation, making it a robust choice for any setup.

Versatile and Energy Efficient

Suitable for various grow areas, the HortiONE 420 can perform in spaces ranging from 60 x 60 cm to larger setups. It consumes only 150W, making it an energy-efficient option without compromising on light output. This facet makes it ideal for both small-scale and large-scale indoor gardening.

Complete Package and Easy Upgrades

The HortiONE 420 comes with everything you need to get started: an LED reflector, driver, suspensions, and a manual. Additionally, it’s compatible with HortiONE dimmers and controllers, allowing you to customise and upgrade your lighting system as needed.

Using the HortiONE 420 in your hydroponic setup is straightforward and user-friendly. Follow these tips to ensure superior performance and plant growth.

Setting Up Your Grow Light

First, determine the ideal location for your Grow Light. It’s perfect for use in grow tents or grow rooms. Ensure your grow area dimensions match one of the recommended setups: 60cm x 60 cm, 80cm x 80 cm, or 100cm x 100 cm.

Hanging the LED Panel

Next, use the provided suspensions to hang the LED panel. Attach the suspensions to the designated points on the panel. Alter the height according to the needs of your plants. For seedlings, hang the light 60 to 75 cm above the plants. For vegetative growth, maintain a distance of 45-60 cm. During flowering, lower the light to 30-45 cm for maximum light exposure.

Connecting the Power

Connect the LED driver to the panel using the 2m connection cable. Ensure all connections are secure. Plug the driver into a power source. The HortiONE 420 supports universal input voltages (110/230, 90-305 Vac), making it versatile for various regions.

Adjusting Light Intensity

Although the HortiONE 420 is powerful, you might need to adjust the light intensity. Use the compatible HortiONE dimmer or knob-bluetooth-dimmer to fine-tune the brightness. This step ensures your plants receive the optimal light intensity at different growth stages.

Monitoring and Maintenance

Regularly check the light’s position and adjust as your plants grow. Ensure the environment remains within the specified temperature range (0 – 35°C) and humidity levels (less than 90% RH). Clean the LED panel periodically to maintain maximum light output and efficiency.

Optimising Your Grow Area

For the best results, combine the HortiONE 420 LED with reflective materials in your grow tent. This method maximises light distribution and ensures your plants receive uniform lighting. Check out the HortiONE website for more information about this LED and their other amazing products here.

How do I know if this LED is the right size for my Grow Tent?

Choosing the right size LED for your grow tent depends on your tent dimensions and plant needs. The HortiONE 420 LED is ideal for grow areas of 60 x 60 cm and 80 x 80 cm. For larger areas, consider using multiple panels. For example, two HortiONE 420 lights cover a 100 x 100 cm space efficiently.

Is this LED suitable for all Plant Growth Stages?

Yes, the HortiONE 420 LED Grow Light is suitable for all plant growth stages. Its full-spectrum lighting supports both vegetative and flowering phases. The combination of Seoul 3030C and OSRAM deep-red LEDs ensures your plants get the right light wavelengths throughout their life cycle. This versatility makes it an excellent choice for continuous use from seedlings to harvest.

Do I need a dimmable LED?

A dimmable LED is beneficial for adjusting light intensity based on plant growth stages. The HortiONE 420 LED is compatible with HortiONE dimmers, allowing you to control brightness easily. During early growth stages, lower light intensity is sufficient. As plants mature, increasing the light intensity ensures robust growth and flowering. Therefore, having a dimmable option provides flexibility and optimises plant health.
