Indoor gardening has become increasingly popular over the years, and with good reason. With the right tools and equipment, you can grow healthy, consistent, high-yielding plants all year round. The key to a successful indoor garden is having the right grow light, and the 450w quantum PAR LED grow light from 4Seasons has been through many generations of the years within NZ, providing world-leading results to our very own growers.


Samsung LM301H and OSRAM Diodes

At the heart of the 4Seasons 450W Quantum PAR LED Grow Light lie the prestigious Samsung LM301H and OSRAM diodes. Renowned globally for their excellence, the Samsung LM301H diodes, with a blend of 3000K and 5000K CCT, ensure the highest quality indoor grow lights available. This spectrum is carefully designed to cater to every stage of plant development, from seed to harvest, providing the perfect balance of light for photosynthesis.

The integration of OSRAM diodes at 660nm and 730nm wavelengths further enriches the grow light's capabilities. These specific wavelengths offer a pronounced focus on flowering and fruiting phases, enhancing floral density and development. This formation of diodes establishes an ideal environment for both vegetative growth and flowering, ensuring healthier and more abundant yields.
