The Grower’s Choice 315w CMH/LEC Lamps are suitable for use in all standard 315w CMH/LEC fixtures. 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
