All our FUSION LED Grow Lights have two (2) primary switches that give you full control over the TrueSun Smart Spectrum built into your light - the Veg switch and the Bloom switch. A third switch for UV-Boss Mode is available on BloomBoss FUSION Pro Series LED grow lights only.
Switch #1 - Veg Mode - (Veg Switch On ONLY)
The Veg stage begins when your plants start growing new leaves and stems. Turn on the Veg switch only during this stage of your garden. This will activate the ideal light spectrum for this stage of growth.
Switch #2 - Bloom Mode - (BOTH Veg + Bloom Switches On)
The Bloom stage of any garden is the most exciting and satisfying because all of your time and hard work begin to pay off.
BOTH the Veg AND Bloom switches should be turned on at this time, to assure your plants are receiving just the right light to produce a bountiful harvest.
Switch #3 - UV-Boss Mode (FUSION Pro Series ONLY) - (All Switches On - Veg + Bloom + UV)
The UV switch should be turned on IN ADDITION TO the Veg and Bloom switches during the final stages of your garden’s Bloom cycle. The addition of UV-A light has been proven to maximize the potency and active compounds of certain plants.
Typically, UV-Boss Mode is only used during the final two weeks of the growth cycle. However, some growers opt to use UV-Boss Mode throughout the entire life cycle or to harden plants before moving them outside.
The combination of TrueSun Smart Spectrum and UV further develops and enhances the natural appearance of your plants.
