Grower's Choice 315W Single Ended CMH Bulb

Grower's Choice 315W Single Ended CMH Bulb

Ceramic Metal Halide lamps are the pinnacle generation of HID lighting. Utilizing ceramics materials instead of quartz for the construction of the arch tubes, which contain the metal halide gas that causes the lamps to operate at higher temperatures, increasing efficiency and providing a more complete spectrum, covering the inadequacies standard MH and HPS poses.

This makes CMH lamps a better option for horticulture as they efficiently produce more light across the PAR spectrum where it matters most.

Grower’s Choice has four different CMH spectrums lamps to customize the light output for every stage of plant growth for optimal harvest potential. For growers using dual lamp models lamp spectrum can be further customized by utilizing different spectrum lamps in the same fixture. We found that 3k + 3K-R provides the best results during the flowering phase, finishing with the 10k lamp in during the last 1 week before harvest.

3K 315W Single Ended CMH:

• Color: 3100K
• Type: SE-CMH
• Wattage: 315W|
• Initial Par: 570 umol/s
• CRI: 90
• Hours: 15,000

Grower’s Choice 3k-CMH lamp utilizes a full phase spectrum that is designed to be used in all stages of growth but optimized for bloom. With a Color Rendering Index of 90 the GC 3k spectrum is very close to natural sunlight but with modest blues, extra red and UV light to serve your plants photosynthetic needs during the flowering phase increasing yields and resin production. Completely silent in operation.

• Contains precision gasses for enhanced spectral output
• Generates much less heat than HPS and MH  
• More closely matches sunlight than ANY other lighting solution available
• Growers report tighter inter-nodal spacing and better yields on flowering plants

3K-R 315W Single Ended CMH

• Color: 3000K
  
• Type: SE-CMH
  
• Wattage: 315W
  
• Initial Par: 540 umol/s
  
• CRI: 90
  
• Hours: 15,000

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

4K 315W Single Ended CMH

• Color: 4200K
  
• Type: SE-CMH
  
• Wattage: 315W
  
• Initial Par: 540 umol/s
  
• CRI: 98
  
• Hours: 15,000

Grower’s Choice 4k-CMH Daylight lamp is the best option for hearty vegetative growth leading to a healthy bloom phase. With a Color Rendering Index of 98 and intense full spectrum the Grower’s Choice 4k lamp provides near sunlight photon output. This leads to healthier and more robust vegetative growth.

• Contains precision gasses for enhanced spectral output
  
• Generates much less heat than HPS and MH  
  
• More closely matches sunlight than ANY other lighting solution available
  
• Growers report tighter inter-nodal spacing and better yields on flowering plants

10K 315W MH Finishing Lamp

• Color: 10,000K
  
• Type: SE-MH
  
• Wattage: 315W
  
• Initial Par: 450 umol/s
  
• CRI: 90
  
• Hours: 10,000

The addition of 10K UV light towards the end of the bloom cycle increases resin production in flowering plants as a defense mechanism in response to the ultraviolet light. Now, growers using CMH fixtures can get these benefits too with the industry’s first and only 315w 10K MH Finishing Lamp.

• For use in 315w CMH fixtures
  
• Strong UV peaks for increased resin production 
  
• Can be used for 25+ flower cycles before replacement
  
• Use only in the last 7-14 days of flowering 
  
• Durable quartz glass arc tube ensures long usable life
