Options for growing in winter:
Houseplants – houseplants are more popular than ever and they are a great hobby for all ages. Houseplants need a bright window with indirect light or you can use grow lights. Beware of drafty windows in winter and monitor plants weekly for moisture, insect pests, and other issues. Since there is not a lot of growth in winter, a weak fertilizer can be used every 2-4 weeks.
Hydroponics – there are a variety of quality, tabletop options for growing hydroponically. Lettuce, herbs, cherry tomatoes, peppers, and a variety of other things can be grown. There are miniature plant varieties on the market that are great for these small units. A good aquarium-type pump is needed to aerate the water, and a good quality grow light is needed. Nutrient management of the water is also needed.
