Growers Choice 315W Single Ended CMH Bulb, 10,000K Reviews

10,000k Bulbs do their job well.
I was skeptical at first but after 2 weeks over the canopy...Definitely bulbs worth investing in. I use Philips 4200k and 3100k bulbs until the final two weeks and replaced with the 10K. Great results with alot, ALOT more resin production. Side by side comparisons do not lie. 10k bulbs for the final two weeks from now on.

Great costumer service
Really nice bulbs . High quality packaging and every temperature for ur every needs. Great prices. Some of the best pricing and customer service on the web. Will be buying more in the future . Thanks hydrobuilder
