Grower's Choice Bloom Boost UV-R Bar Set | 2 UV Bars for ROI-E720

Bloom Boost UV-R Set: What Is in the Box and How It Connects This set contains 2 UV bars built for one fixture, the Grower's Choice ROI-E720. The bars clip onto the fixture frame with the included mounting clips. Power and control run through an RJ14 cord to the light, so there is no separate outlet or timer to wire. There are 6 wavelengths in the mix, spread across UV-A, UV-B and infrared, plus white diodes. The housings carry an IP65 rating, which suits humid flower rooms and routine wipe-downs. Draw is small, about 10W, so the bars barely change a room's electrical or heat load. The set supports plant health, sturdy growth and higher resin output. The bars do not fit other brands or other Grower's Choice models. The main light is not included. Running a UV Grow Light Bar in Late Flower A uv grow light bar is a finishing tool, not a source of growing light. Most growers leave it off through veg and early flower, then switch it on for the last few weeks. Start with short daily sessions, often two to four hours in the middle of the light period, and watch the upper leaves. Curling, bronzing or bleached tips mean the dose is too high, so shorten the window or dim the bars. Some cultivars take UV well, while others stress fast, so test one bench before the whole room. The GC Master Controller, sold separately, schedules and dims the bars with the rest of the Grower's Choice fixtures. Without it, set output with the dimmer switches on the units. Protect your own eyes and skin, because UV-B burns quickly at close range. Wear UV-rated glasses and sleeves when you work under the bars. Running them only on a timer while the room is empty keeps exposure low. If you run a different fixture, this set will not connect.
