QUESTION: Can basil grow without sunlight? I’d like to grow it indoors, but my house is pretty dark.
ANSWER: When planted outdoors, basil prefers a spot that gets six to eight hours of full sun a day, but it can tolerate partial sun instead. If you live in the south or southwestern U.S. where summers can be a bit brutal, basil will benefit from some afternoon shade.
But if you’re growing basil indoors, it needs at least six hours of sunlight per day and does best in a south-facing sunny window. If you don’t have that much sun available in your home, you can grow basil under fluorescent or LED grow lights for 10 hours per day as a substitute or use a combination of sunlight and grow lights.
