The HTG Supply 400-Watt HPS System is a powerful and efficient lighting solution designed to meet the needs of indoor cannabis growers. It combines a high-output HPS bulb with a remote ballast and reflector to provide optimal light coverage and intensity.

When it comes to electrical specifications, the HTG Supply 400-Watt HPS is quite impressive:

  • Power Consumption: 400 watts
  • Current Draw: Approximately 3.33 amps at 120 volts

The ballast features a built-in 10′ power cord with a standard household grounded plug (NEMA 5-15) and a built-in 10′ socket-to-ballast cord with a mogul-base socket. These features make the setup straightforward and convenient for any grower.

One of the standout features of the HTG Supply 400-Watt HPS is its innovative open-air remote ballast design. This design helps to dissipate heat more effectively, ensuring the system runs cooler and prolonging the lifespan of the components. The ballast handle features keyholes for easy wall mounting, providing flexibility in your grow room setup.

The heart of this system is the high-output 400-watt HPS bulb. This bulb delivers an enhanced horticultural spectrum and outputs 55,000 lumens, providing ample light for plants to photosynthesize and grow. The spectrum of light emitted by the HPS bulb is ideal for the flowering stage of cannabis, promoting robust bud development and higher yields.

For optimal results, the HTG Supply 400-Watt HPS system is recommended for a coverage area of 4′ x 4′. This makes it suitable for small to medium-sized grow rooms. Ensuring even light distribution within this area will help your plants receive the necessary light intensity across the canopy.

Setting up the HTG Supply 400-Watt HPS is hassle-free thanks to its compact design. The ballast measures 9″ long, 4″ wide, and 5.5″ high, while the reflector measures 16″ long, 13″ wide, and 6″ deep. The system includes hanger attachment hardware, allowing you to position the light fixture precisely where your plants need it most.

The high lumen output and optimized light spectrum of the HTG Supply 400-Watt HPS system ensure your cannabis plants receive the light they need for vigorous growth. The system supports both the vegetative and flowering stages, helping you achieve bountiful harvests.

Despite its powerful output, the HTG Supply 400-Watt HPS system is energy-efficient. Its design minimizes energy consumption while maximizing light output, making it a cost-effective choice for long-term use.

Constructed with high-quality materials and featuring an open-air remote ballast design, the HTG Supply 400-Watt HPS system is built to last. It can withstand the rigors of continuous use in indoor gardening environments, providing reliable performance over time.
