Yes, succulents can grow well under grow lights as long as the light is bright enough and provided for a long enough duration each day. The best type of grow light to use for succulents is a fluorescent tube light. For smaller succulents, you may need to provide light for 12-16 hours per day, while larger succulents will do fine with 8-10 hours of light each day. Be sure to place your succulents close to the grow light so they can receive adequate lighting.
