Year-Round Veggie Garden
If you enjoy gardening in the summer and harvesting fresh vegetables, you can also enjoy fresh vegetables in the off season from an indoor container garden.
I’ve already begun my green beans and peas indoors for a early harvest, and will continue to grow them starting indoors again in summer and will continue year-round. I’m considering taking out two shelves in my greenhouse to keep a few tomato plants over the winter 
You’ll need to be sure you have proper lighting, adequate watering, proper containers, and know how to pollinate by hand, if necessary. Some plants like beans, peas and tomatoes are self pollinating meaning you don’d need to do anything to help the process. Others you will need to do by hand, with a paint brush, cotton swab, or other small object to transfer pollen from the male flowers to the female flowers. When properly done, you should only have to do this once.
Here are step by step instructions
