LED Lighting
Growing outdoors is difficult, because there are so many uncontrollable variables, including pests, temperature, humidity, and sun. As a result, outdoor-grown weed is usually less consistent in levels of THC and other, medicinally important cannabinoids.
Many growers choose to grow indoors or in a greenhouse—or a combination of the two—both of which require LED lighting. Austin-based Fluence Bioengineering leads the pack of cannabis-specific LED lighting companies, along with Emeryville, California–based Lumigrow, Austin’s Illumitex, and Sweden’s Heliospectra, which makes “tunable” lights that fade in and out like the sunset and sunrise.
