FAQs
Yes, the Sun White spectrum and dual switches make it ideal for both vegetative and flowering stages, providing the necessary wavelengths for every phase of development.
You can connect up to 4 units on a standard 120V circuit or up to 8 units on 208V-277V circuits, allowing for easy expansion in larger grow rooms.
No, this fixture features a ballast-free design. It uses ballast-bypass LED lamps, which eliminates the common failures, buzzing, and flickering associated with traditional T5 ballasts.
We recommend a hanging height of 12-24 inches above the plant canopy. For high-light plants like cannabis, 12 inches is optimal, while 24 inches is suitable for leafy greens or seedlings.
The Sun White spectrum is superior because it features a high 95 CRI and includes far-red wavelengths. This triggers the Emerson Effect for faster growth and makes it much easier to see the true health of your plants.
