How to Grow Herbs Indoors Without Sunlight

More and more home cooks and gardeners are growing plants inside, but not everyone has sunny windowsills or enough natural light. With the right tools and info, you can grow herbs indoors without sunlight. This is true whether you live in a basement apartment, have windows that face north, or just want to make the most of the space you have inside. This whole book will teach you everything you need to know about growing herb gardens that do well with little or no light.

Understanding Light Requirements for Herbs

Before you learn how to grow herbs without sunlight, you should grasp why plants need light and how to generate artificial light conditions. Plants use photosynthesis to transfer light energy into chemical energy that helps them develop. Light is the major source of energy for this process. People commonly put herbs into three groups based on how much light they need: high-light, medium-light, and low-light.

Most cooking herbs like to be in full sun and need six to eight hours of direct sunshine per day. But it doesn’t mean they can’t do well in fake light. In fact, controlled indoor conditions frequently yield more reliable results than relying on natural light, which can change at any time. This is especially true in places where the weather is terrible or there isn’t much sun.

You need to know what kind of light plants need and how much of it they need to grow herbs inside without sunshine. Plants grow leaves and stems with blue light (400–500 nanometers), while they flower and make fruit with red light (600–700 nanometers). You may create the optimal conditions for growing your herbs all year long by utilizing artificial lights to give them the correct blend of these wavelengths.

Choosing the Right Artificial Lighting

If your herb garden doesn’t get any sunlight, the right artificial lighting is the most important thing. There are numerous types of grow lights, and each one has its advantages and disadvantages for growing plants inside.

LED grow lights have transformed how people grow plants indoors in the last few years. Due to their low electricity consumption, you can position these lights closer to your plants without fear of burns. Full-spectrum LED lights provide herbs all the wavelengths they need to grow well. Many models let you alter the wavelengths for different stages of growth. LED lights may cost more at first, but they are more cost-effective in the long run because they last 50,000 hours or more and use a lot less energy.

Fluorescent lights, especially T5 and compact fluorescent lamps (CFLs), are still a popular choice for growing herbs. These lights are easy to locate, don’t cost too much, and don’t create as much heat as conventional electric bulbs. T5 fluorescent lights are wonderful for herbs because they give off a lot of light and are powerful. But they use more power than LEDs and need to be changed every 10,000 to 20,000 hours.

High-intensity discharge (HID) lights, such as metal halide (MH) and high-pressure sodium (HPS) bulbs, throw off a lot of light but use a lot more electricity and heat. These lights can be quite useful, although they are usually better for larger growing projects than for little indoor herb gardens. To keep plants safe, the heat output needs to be well-ventilated and set in the right spot.

You should think about how many plants you want to grow, how much money you have, how much space you have, and how much electricity costs when you buy grow lights. Most home herb gardens benefit from a combination of full-spectrum LED panels and T5 fluorescent lights, as they offer a cost-effective solution without overheating the growing area.

Setting Up Your Indoor Herb Garden

To make a home herb garden operate properly, you need to plan and set it up carefully. First, find a comfortable place that works well with your lighting system and is easily accessible for maintenance and harvesting. You can use basements, spare rooms, closets, or even kitchen counters as long as you can keep the temperature and light under control.

The distance between your lights and your plants is highly significant for their health. Fluorescent lights can be 6 to 12 inches away from your herbs, while LED lights should be 12 to 24 inches above them. Watch your plants closely and modify their height as appropriate. If the leaves appear scorched or bleached, adjust the lights upward. If the plants get tall and thin, move the lights down.

You might want to use things that reflect light to get the most out of it. Mylar sheets, white paint, or aluminum foil can help you reflect light onto your plants. This will ensure they all get equal light and reduce the number of outlets needed. Many indoor gardeners create simple grow tents or boxes lined with light material to provide optimal conditions for plant growth.

Timing is also very crucial when employing fake lighting. Most herbs need 12 to 16 hours of light per day to thrive well. A timer helps you remember to turn lights on and off and keeps the lighting on a regular schedule. Some farmers want to keep the lights on all the time to speed things up, but most herbs require some time in the dark to finish their natural metabolic processes.

Best Herbs for Low-Light Indoor Growing

All herbs can grow under artificial lights; however, certain types thrive better inside and don’t need as much light as others. Knowing which herbs do well in dim light will help you succeed and save you money on electricity bills.

Mint plants are some of the easiest herbs to grow indoors without sunlight. Spearmint, peppermint, and chocolate mint are all varieties of mint that can grow quickly in artificial light and don’t need a lot of light. These herbs do best in containers because they like soil that is always moist and can spread quickly. You may use fresh mint in teas, cocktails, and cuisine just a few weeks after you cultivate it, since it grows so quickly.

It’s not difficult to grow both flat-leaf and curled parsley indoors. This herb grows slowly but steadily under artificial lighting. It only grows every two years, so you can use the leaves to cook with. Moderate light and steady moisture are optimal for parsley, which is why it’s a good choice for beginners. The plant is also ideal for narrow spaces or shelves because it grows close together.

Chives are another easy-to-care-for plant that may be cultivated indoors. These herbs taste like onions and grow in groups. Their leaves are hollow and look like grass, which makes them perfect for decoration. Chives can grow in less light than many other herbs. If they receive enough light, they can even bloom inside. Picking the plant regularly stops it from turning woody and helps fresh development.

Cilantro is known for bolting quickly when it gets hot outside, but it does well in regulated indoor settings. The consistent light and heat restrict the plants from blossoming too soon, so you can pick them for longer. This annual grows quickly and has new leaves that can be used in salsas, curries, and other dishes within 3 to 4 weeks of sowing.

Other herbs that do well in artificial light are oregano, thyme, sage, and lemon balm. Many people frequently believe that growing basil in low light is difficult, but smaller varieties like “Spicy Globe” or “Greek Miniature” can thrive with proper care and sufficient artificial light.

Soil, Containers, and Nutrients

Lights can help all flowers develop, but some do better inside and need softer light than others. If you know which herbs do well in low light, you’ll have a better chance of success and save money on electricity bills.

Some kinds of mint may thrive inside without sunshine fairly easily. Spearmint, peppermint, and chocolate mint are the three main types of mint. All three can grow swiftly in artificial light that isn’t as bright. These herbs grow best in containers because they like soil that stays moist and may spread out quickly. Because it grows so quickly, you can use fresh mint in food, drinks, and teas just a few weeks after it is grown.

You may easily cultivate either flat-leaf or curled parsley indoors. This herb grows slowly but steadily every two years under false lights, providing you with many leaves to use in cooking. This herb does best under mild light and with steady moisture, so it’s a good choice for beginners. The plants grow close together, so they can also be used in narrow spaces or on a shelf.

You may also grow chives inside. They are easy to care for. These herbs grow in groups and have a taste that is similar to onions. They possess flat, grass-like leaves that are excellent for enhancing the aesthetic appeal of various arrangements. Chives may thrive in low light better than some other herbs. They can even bloom inside if they receive enough light. Picking the plant often stops it from growing woody and helps it grow new leaves.

Coriander is known to bolt quickly when it’s hot outside, but it grows best in cold, dark conditions inside. The plants don’t blossom too quickly because the temperature and light stay the same. This advantage means that they can be picked for a longer time. This annual starts to grow swiftly after 3–4 weeks of sowing. It has new leaves that can be used in salsas, stews, and other foods.

Other herbs that thrive in artificial light include oregano, thyme, sage, and lemon balm. People often say that basil can’t grow in low light, but if you take care of it and give it adequate artificial light, “Spicy Globe” or “Greek Miniature” types can do well.

Watering and Humidity Management

It’s very vital to water indoor herbs the appropriate way so they can develop. Since it doesn’t rain or blow outside, you need to monitor the wetness levels closely. This way, you won’t water too little or too much. You should water your herbs when the top inch of soil feels dry to the touch most of the time. But this can differ depending on the herbs you are growing and the conditions they are in.

Oregano, rosemary, and thyme are Mediterranean herbs that do better when the weather is a little drier. You should let them dry out a little bit between waterings. Basil, parsley, and mint are examples of herbs that like to stay damp. They need to be watered more often, but they also need proper drainage. Water it well until the bottom drains off any surplus, then let the soil dry up a little before watering it again.

Indoor air doesn’t always provide the moisture that herbs need, especially in the winter when heating systems dry out the air. Most herbs do best when the humidity is between 40 and 60%. You can increase the humidity by grouping plants, putting pots on rock trays with water, or installing a tiny humidifier near where you’re growing. Do not spray the leaves directly because this can cause fungal illnesses to thrive in the still air inside.

It’s important to keep both the temperature and the humidity in check. Most veggies do best during the day when it’s between 65°F and 75°F (18°C and 24°C). At night, they enjoy it a little cooler. Do not put herbs near windows that let in a lot of draft, air fans, or heaters. Many herbs fare well when grown indoors since they don’t have to worry about the weather changing outside.

Common Challenges and Solutions

Growing herbs indoors without sunlight might be hard, but understanding these problems can help you avoid them or fix them fast. Getting rid of pests is critical in tiny areas since issues can spread quickly. Aphids, spider mites, and fungus gnats are all common indoor pests. Regularly checking your plants helps you discover pests before they become a serious problem. You can use insecticidal soap or neem oil to kill pests, or you can let ladybugs and other beneficial insects do it.

Fungi grow nicely in indoor gardens because the air is calm and damp. Use small fans to keep the air moving, don’t water from above, and make sure the plants are spread out properly to minimize difficulties. If you observe powdery mildew, leaf spots, or any other fungal problems, get rid of the leaves that are damaged straight away and make sure the air can flow better. In some circumstances, organic fungicides may not be enough, and the plant may need to be replaced entirely.

A long growth period usually suggests that there isn’t enough light or that it doesn’t last long enough. If your herbs have lengthy roots that reach toward the light and not many leaves, bring the lights closer or leave them on longer each day. On the other hand, dark green leaves and slow, dense growth could signal that there is too much light or fertilizer. Change what you need to and see how the plant responds.

If a plant doesn’t receive enough nutrients, its leaves may become yellow, it may develop slowly, or its color may change. When plants don’t get enough nitrogen, their older leaves turn yellow. When they don’t get enough iron, they cease growing new leaves. Regularly fertilizing may usually keep these problems from happening, but in some situations, you may need to take special nutritional supplements. Don’t only treat the symptoms; always find out what caused them.

Maximizing Yield and Flavor

The major reason people grow herbs is to produce plants that smell good and taste good that they can use in cooking. There are a few things you can do to get the most out of your indoor garden in terms of both taste and yield. Picking annual herbs regularly makes them grow bushier and keeps them from blooming. Cut or pinch the stems right above a leaf tip. Don’t take away more than a third of the plant at once.

A lot of the time, stress can make herbs taste better. Letting the soil dry out a little between waterings will make the essential oils stronger, which will make the flavors stronger. But remember that such actions shouldn’t come before the plant’s health demands, because long-term stress affects productivity overall. Some farmers stop using fertilizer before harvest to make the flavors richer, especially with Mediterranean herbs.

Putting plants together works inside and outside. Growing herbs that mix well together might help your plants develop healthier and keep bugs away. Eating basil and tomatoes, rosemary and sage, or chives and parsley together is a terrific idea. You should avoid having too many pets in one place, but grouping them can help create good microclimates and make care easier.

If you want to keep harvesting, think about succession growth. Every two weeks, plant new seeds or cuttings so you always have fresh herbs. This strategy works best with fast-growing annuals like basil and cilantro. Keep plants at distinct stages of growth to avoid cycles of “famine or feast.”

Advanced Techniques and Technologies

You might want to try more intricate ways to make your setup function better as you get skilled at growing herbs indoors. Hydroponic systems don’t use dirt at all. Instead, they grow plants in water solutions that are rich in nutrients. These systems can grow plants faster and produce better yields, but they cost more and require more technical knowledge to set up. The ebb and flow approach, the nutrient film method, and deep water culture are all beneficial for plants.

Smart growing systems that use technology can take care of a lot of the work involved in indoor gardening. These systems may modify when the lights come on, monitor how wet the soil is, change how much fertilizer is sent, and even send you alerts on your phone. They are excellent for busy farmers or farmers who wish to have complete control over the environment, even though they cost a lot.

Vertical growth makes the most of small spaces by stacking plants in towers or on the walls. This method works well with a few herbs and can turn small rooms into gardens that grow food. Make sure that all of the floors get enough light, and turn the plants every so often to make certain they grow equally.

Propagation methods let you make your garden bigger without having to acquire additional plants. You can swiftly develop roots from the cuttings of many plants in water or a mixture of moist soil. Basil, mint, oregano, and sage may all easily develop new plants. When herbs like chives and lemon balm grow together, dividing them is a smart way to separate them. Keep seeds from herbs that grow every year on hand so you always have some.

Conclusion
