To get started, you'll need to select an appropriate container for your indoor tomato plants. The most suitable pots are between 10 to 12 inches deep and wide, as they provide enough space for the roots of your plant to spread out and develop properly.

You can choose a pot that's made of any material you like but some are more suited for certain plant types then others -- From a breathable material like terracotta to swankier pots like porcelain. Just remember terracotta will dry the soil faster, providing adequate drainage.

Additionally, ensure that your containers have drainage holes. This is crucial, as tomato plants need very good drainage to avoid any root rot.

Location Matters

Tomatoes need plenty of sunlight, so it's important to place your container in a bright spot with at least six to eight hours of direct sun each day. In the winter, a south-facing window is ideal; On short winter days, they can provide the most sunlight. If you’re growing tomatoes indoors in the summer, east or west-facing windows are best.

If you don’t have enough natural sunlight in your home, you can also use grow lights for your tomato garden. Remember, grow lights differ from sunlight. If you’re growing tomatoes under these conditions, your plants need approximately 16 to 18 hours of light per day. When possible, avoid incandescent bulbs as they can burn your tomato plants. Instead, opt for LED or fluorescent bulbs.

Keep an eye of your tomato plants for signs of sun damage such as yellowing or wilting leaves.

Water Wisely

Tomato plants require consistent watering to thrive indoors, especially when temperatures are high, and humidity is low. Your plants will show sing of dehydration when they are thirsty, such as dry, wilted, or yellowing leaves.

It’s best to water them deeply once per week, depending on the soil dryness and the heat levels in the room they’re growing in. If in the heat of summer you decide to move your tomatoes outdoors, you'll need to increase watering about once a day, or 2 inches of water per week.

With tomatoes, it’s best to let the soil dry out a bit before watering. When performing this task, saturate the soil evenly and avoid getting water on the leaves of your plants or you risk diseases like leaf spot.

Support Your Plant

As tomatoes continue to grow, they may need additional support in order to stay upright without leaning or drooping. Staking is an effective way to keep your tomato plants stable.

Choose a strong stake that won't tip over easily if it's placed too close to the plant’s stem. You can also use a cage around the plant for additional support.

Good Quality Seeds

A good quality seed is essential for any successful indoor garden, so invest in organic varieties. Chemical-treated seeds are not ideal for indoor growth as they often contain pesticides and antibiotics which you don’t need in an indoor setting. Look for organic seeds at your local nursery, health food store, or online.

When choosing the type of seed you want to grow indoors, pay no attention to the hardiness zone information on the packet. You don't need to worry as much about your zone when growing indoors. For maximum success, research different varieties that are best suited to growing indoors and select accordingly.
