Quick Answer:

Winter greenhouse gardening focuses on growing cool-season crops that thrive in lower light and cooler temperatures, like lettuce, spinach, kale, carrots, and herbs. To keep plants healthy, maintain a temperature range of 45-65°F (7-18°C), provide  12-16 hours of light, and water sparingly in the morning. Consistent airflow, light fertilizing, and good soil drainage will keep your winter garden productive and vibrant all season long.
