The full phase spectrum of the ROI-E900 is a fixture that distributes the whole spectrum of light to your plants, providing them with just what they need to develop large and beautiful. Grower's Choice's well-known GC-3K Full Phase Spectrum uses the best LED diodes on the market to help your plants grow to new heights.

Because the ROI-E900 LED Grow Light has strict power needs, this fixture puts out between 2000 and 2600 umol/s. At 1050 watts of power, this system is only 2.6 umols/J efficient. With a voltage range of 120 to 277 volts and the ability to dim the light, you can find the right amount of power output and power use. With energy savings of up to 40% and 40% less need for HVAC, the ROI-E900 really pays for itself.

The ROI-E900 LED Grow Light comes with a set of horticulturally designed supplemental bars that help provide a key spectrum that will promote overall health, strong plant growth, and more resin production than the 10K finishing bulbs. The new UV-R bar set is specifically made to pair with the ROI-E900. It just needs to be plugged in. No extra wiring is needed. With a GC-Master Controller, you can control and dim the bar itself. The UV-R bar set is a full-spectrum UV light fixture made for gardening. It has 6 different wavelengths, which makes it a full-spectrum UV solution for growing plants.

The ROI-E900 LED Grow Light can be controlled easily with a Grower’s Choice Master Controller and is also compatible with all kinds of quality master controllers. This feature allows cultivators to set the fixture to turn on and off at the times they want. They can also program sunrise and sunset settings, dimming options, and fail-safes that dim or turn off the lights if the room temperature gets too high, like if the HVAC system stops working. This could save gardens from heat damage. This dual-channel controller allows daisy-chaining up to 100 fixtures per zone. It gives you full control over your growing environment by letting you turn lights on and off at set times, control sunrise and sunset, and get accurate temperature readings with dual thermal probes and thermal-threshold auto dim-shutoff for extra safety.
