Yes, sweet peas can be grown in a greenhouse, where they will benefit from the warm, humid environment. Sow the seeds in moist, well-draining soil in early spring, and keep them warm and moist until they germinate. Once they have germinated, move them to a cooler area with plenty of light to prevent them from becoming leggy. Once the plants are established, provide support for climbing varieties and keep them well-fed and watered.
