Introducing the world’s first 1,000W Ceramic Metal Halide lamp. As a direct replacement for your existing 1,000 watt HID fixtures, this 1,000W CMH lamp provides the absolute highest photosynthetically active radiation (PAR) to your specialty flowering plants. Emitting an astonishing PPFD and with an extremely high CRI this lamp will not only increase your overall dry weight but will also raise the quality of your harvest. Grower’s Choice has continuously produced the world’s most accurate spectrum, closely replicating the sheer power of the sun. By using existing double-ended fixtures with our new 1,000 watt CMH lamp you can completely overhaul the lighting in your facility, and enjoy watching your yields increase as your temperatures decrease.

The 3K-R is an enhanced version of our 3K Lamp that is designed specifically for plants that are prized for their resin production. It is similar to the original 3K, but it has contains a few subtle differences:
  • A slight increase in UV light to promote resin production
  • A taller peak in the Far-red to stimulate metabolic activity during flowering
  • Slightly higher PAR for better flower density
  • Increased intensity in red
