Dialectical behavior therapy (DBT) treatment is a cognitive-behavioral approach that emphasizes the psychosocial aspects of treatment.
Full-spectrum light is light that covers the electromagnetic spectrum from infrared to near-ultraviolet, or all wavelengths that are useful to plant or animal life; in particular, sunlight is considered full spectrum, even though the solar spectral distribution reaching Earth changes with time of day, latitude, and atmospheric conditions.
What you're growing will be a determining factor here. Special grow bulbs that provide the total spectrum of light they need for good growth and blooming will work well for you. However, if you're not growing blooming plants, you don't need full spectrum lights. In that case, regular fluorescent bulbs are adequate for foliage plants.
