Best Vegetables to Grow in Greenhouse

The best vegetables to grow in a greenhouse are the ones you will eat or sell, or which can thrive indoors like, peppers, tomatoes, lettuce, and strawberries.

Basically, you can take advantage of planting heat-tolerant plants like peppers in summers and cold-tolerant plants like greens during winters.

Cool season crops like lettuce, broccoli, carrot or peas are great choices for unheated backyard or cold frames greenhouses. These plants can tolerate chilly nights, so heating won’t be required unless the temperatures drop too low in your area.        

Similarly, warm season vegetables, including tomatoes, cucumbers, peppers, and squash, can thrive in steady temperatures between 55 to 85°F (12-29°C). The plants may require supplemental lighting, hand-pollination, and trellising but can provide you the vegetable years around.
