You’re right in saying that the biggest challenge is the amount of light. Herbs including mint do best when grown in a very sunny window that receives between 6 to 8 hours of direct sunlight each day (typically a southern or southwestern exposure). When growing herbs under natural light, be certain to rotate the pot every 3 to 4 days to ensure uniform growth of the plant. If your windows do not offer enough sunlight, you can supplement natural lighting with fluorescent light. In general, for every hour of required sunlight, expose the plants to two hours of fluorescent light. Herbs grown entirely under fluorescent lights will require between 14 to 16 hours of artificial lighting. Place herb plants no closer than 5 or 6 inches and no farther than 15 inches from the light source.
