Horticultural Lighting Fixture
Vegetative Footprint: 4' x 4'
Flowering Footprint: 3' x 3'
3,100K - Full Phase
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.
3,000K-R - Red Enhanced
Growers Choice 3kr-CMH lamp is tailored specifically to enhance bloom production through the discharge of intensified red shift photon dispersion, which plants need to promote heavier yields and additional UV light to facilitate terpine and resin production as this is a plant’s natural response to protect itself from UV radiation.
4,200K - Day Light
4K CMH: 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.
10,000K - Finishing
Grower’s Choice final phase 10k-CMH finishing lamp should be used during the last week to two weeks before harvest and is specifically designed to emit photons mainly in the ultraviolet 350-425 nm wavelength. As high amounts of UV light cause damage to plant cells, plants compensate in order to protect itself and facilitate reproduction by releasing more resinous oils which translates into a higher quality yield
The GC-315 and GC-1000 Digital Ballasts allow lamps of various wattages to be operated in the same unit simply by adjusting the dial on the ballast. Each lamp will be operated to the exact specification that the lamp requires.
Smart Step Technology
By turning the dial on the GC Series Digital Ballast you can reduce the output of a lamp when not so much power is needed. Just turn the dial again to step back to full power.
The Super Lumen feature on GC-315 and GC-1000 will increase the output of the ballasts highest wattage lamp to achieve maximum lamp performance. Increase is approximately 10% depending on model.
AI Ignition Control
This revolutionary feature, unique to our products, makes GC Series Digital Ballast the safest and most reliable ballast when used in automated multiple lamp applications. When multiple
units are connected to the main circuit our integrated Ignition Control software will completely balance the electrical draw, by igniting one lamp at a time to prevent electrical surges and spikes that can overload the mains circuit and trip circuit breaker systems. For further efficiency, this feature is activated alongside our ‘Soft Start Technology’.
Soft Start Technology
Soft Start Technology prolongs lamp life by stopping current rush to the lamp and preventing lamp overload. When the ballast is started from cold there will be a 3 second fixed delay before ignition. After ignition there will be a series of random 0-2 second delays before full brightness is reached after approximately 3-5 minutes. SoftStart Technology is also activated when increasing and decreasing power to the lamp using the 'Smart-Step' feature.
Re-Strike of Hot Lamp after Mains Failure:
The GC Series Digital Ballast uses a timed re-strike system that prevents the ballast from re-striking a hot lamp after a power failure. If a hot lamp is detected, the re-strike will be delayed for 60 second intervals until the lamp has cooled sufficiently to be re-ignited. Re-ignition is then controlled by 'SmartStart Ignition Control' and 'Soft Start Technology' software.
The GC Series Digital Ballast is suitable for use with all good quality HPS, Metal Halide and Ceramic Metal Halide lamps. For a guaranteed perfect match and the best results we recommend Grower’s Choice horticultural lamps. Grower’s Choice lamps are optimized for use with high efficiency electronic ballasts with adjustable output.
Automatic Frequency Adjustment:
The GC Series Digital Ballast automatically adjusts its output frequency to maintain a constant output regardless of input power fluctuations and ageing lamps. This also prevents 'lamp flicker'.
Full Circuit Protection
The GC Series Digital Ballast uses a sophisticated software controlled circuit breaking system that is not seen in other manufacturer's ballasts. The system protects against a series of faults including: Open Circuit Protection, Short Circuit Protection, Over Voltage Protection, Under Voltage Protection and Over Temperature Protection. On Ignition the ballast performs a 3 second test of the circuit and in the event of a fault the ballast will go into protection mode to avoid damage to the ballast and lamp.
The GC Series Digital Ballasts' unique case design acts as a superior heat sink making the ballast extremely cool running without the need for internal fans.
The GC Series Digital Ballast has superior RF Shielding with Total Harmonic Distortion (THD) of less than 10% meaning it will not interfere with television or radio equipment.
The GC Series Digital Ballast has no noisy internal fans and is completely silent in operation.
High Energy Efficiency:
The GC Series Digital Ballast is up to 30% more efficient than standard magnetic ballast producing more lumens of light per watt of consumed energy. Efficiency does not diminish and is maintained for the entire life of the unit.

Light and service are outstanding can’t say better things about this place
Light was shipped quickly and the price was unbeatable.
Packaged well and functions as descibed.
Very happy thus far. Would definitely buy again.
Great product and this is the best price I can find for the growers choice 315 cmh on the internet. I have been searching for weeks and Amazon never fails to be the best priced. Factory Hydro is quick to answer support questions as well. Thumbs up from this guy.
Just ordered this light. Shipped next day and was at my door 4 days later. Great packaging. Small light! Great for saving space. Everything went together just fine. Plugged her in and she ramped up. Minutes or two later she is blazing light. Runs virtually silent and pretty cool. Few hours and I can tell plants are responding well. 3kR bulb for growing legal cannabis or anything you want copious amounts of resin production. Will update in 3 months.
