The Grower's Choice Bloom Boost UV-Bar has been specially designed to work with the ROI-E720. This supplemental bar set is carefully engineered to deliver a crucial spectrum to increase your plant's health, vigorous growth, and maximize resin production – similar to 10k finishing bulbs.

The Bloom Boost UV Bars are easy to use and fully controllable either via an external controller or manually using the switches on the fixture itself. Use the easy-to-follow instructions on the fixture's decals to set the manual dimmer. When pairing this fixture with a controller, you will need RJ14 data cables, and recommends that the Bloom Boost be put into its own separate group when using a controller.
