Growers Choice 315W Single-Ended CMH Bulb - 3,100K


Product Description

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 contains a few subtle differences. This bulb contains precision gasses for enhanced spectral output. It also generates less heat than HPS and MH. The 3K-R 315W Single-Ended CMH more closely matches sunlight than any other lighting solution available. Growers report tighter inter-nodal spacing and better yields on flowering plants.

Product Features

  • 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
