🥑🥑🥑🥑🍊🍊🍊🍊🍋🍌🍋🍋 that is rightI think you would be much better served with bar style led grow lights with that much space.
Bar style lights do not concentrate the light to the center like board style led grow lights. They spread the lights out evenly, allowing you to run the lights much closer to the canopy (typically 6-12 inches). They tend to run much cooler as well.
I would recommend getting a light that is more watts than you need so you can run the fixture dimmed and much more efficient. Most bar style lights rated for a 5x5 ft. light spread will fit in a 4x4 ft. space (or 4x6 ft. in your case).
If you’re on a budget this is a wonderful deal and a good unit by a good manufacturer. They are a site sponsor also.
