The 400W HPS+MH cool tube reflector kit can save growers time and money thanks to the high quality components included:

• Yield Lab 400W High Pressure Sodium (HPS) Bulb – 1 year warranty: HPS bulbs have long been favored by indoor growers, thanks to their ability to accurately mimic the conditions of outdoor propagation. HPS grow light bulbs diffuse the particular portion of the electromagnetic spectrum that is best suited to photosynthesis production, resulting in lush and healthy plants.

• Yield Lab 400W Metal Halide Bulb – 1 year warranty: This high efficiency bulb is another grow light that has proven to be a reliable and productive component in any indoor growers’ arsenal of equipment. The blue spectrum wavelengths (5,500K) make this bulb perfect for the vegging stages of plant production and are particularly well suited to green leafy plants such as herbs or the various types of lettuce.

• Yield Lab 400W Digital Dimmable Ballast – 3 year warranty: With the new dimmable digital technology, the Yield Lab ballast can be adjusted to suit the particular plant species being grown, the relevant stage of the growth cycle and even just the temperature forecast for any given day. The ballast can have the heat emissions reduced by 50% using the dimmer function, saving plants from the risk of overheating during the summer months. This also allows for increased intensity in the late stages of the growth cycle to help plants flourish.

• 6” Yield Lab Air Cooled Reflector Tube – 1 year warranty: Measuring 25” in total length and containing 6” air duct ports, the Yield Lab air cooled reflector tube has been designed to make the most of natural airflow in order to provide sufficient cooling for the grow light kit.
