What is different about the ROI-E720?

The ROI-E720 is a user-friendly commercial-grade fixture. However, Grower’s Choice does not recommend the E720 for inexperienced growers or tent applications. The E720 is designed as a high output fixture for commercial cultivation's, emitting nearly the same PPF as a standard 1000w DE HPS fixture and lamp. With intense PPF, 3k full phase spectrum and balanced PPFD the ROI-E720 has the potential to produce the highest yields and superior quality. GC highly recommends this fixture be used in professional, environmentally controlled cultivation’s that supplement CO2. Without using CO2 the grower may be introducing more light than the plants can process, possibly causing stunted growth or light damage. Know your garden and provide light accordingly.

The 720 increases the wattage from 680 to 720 and includes newer improvements to LED technology. The ROI can also be used in the BOOST mode to increase the PPF of 1870 umol/s to 2050 umol/s (approximately 10%). The ROI-E720 is designed to be slightly more of a replacement for 1000w HPS lights in indoor grow rooms with taller ceilings. If you're growing in a room with lower ceiling height, or in a multi-tiered fashion, it may make sense to use the ROI-E680 instead so you can get closer to the plants without overpowering them with intensity.

You can set the ideal intesity at any time for optimal plant growth without the use of an external controller. If you prefer an external controller, no problem. This fixture is compatible with most lighting contollers including Growers Choice Master Lighting Controller. With the GC master controller, cultivators can set the fixture to turn off and on at desired times, program sunrise/sunset settings, program dimming options and set protective fail safes to dim or turn off fixtures in the event of excessive room temperatures, such as in the event of HVAC failure, potentially saving gardens from heat damage.
