Why Grow Vegetables Indoors?

The freshest indoor vegetables not only taste much better, but fresh vegetables are also richer in vitamins and other nutrients. If you think about it, when you have your indoor vegetable farm, the time from the plant to plate is almost non-existent. Compare this to the time it takes for vegetable plants that are harvested from a commercial farm. Once harvested, they are transported to a warehouse, then distributed to a grocery store, and then finally arrive at your home.

Control over the growth of your vegetables is quite appealing for some people as well. Firstly, you can decide what type of soil your vegetable plants are grown in. Then, you know that it will only be your hands on these plants. After that, you harvest them as needed. Also, you can rest easy knowing no pesticides have been used. By using non-GMO seeds and organic soils is within your control. Having complete knowledge of how your food was grown is the main reason why many people grow their vegetables.

Indoor vegetable farming is an excellent solution for those who don’t have the yard space to grow outside. For those who live in cooler climate conditions, an outdoor garden might not even be an option. Or their growing season might be incredibly short. On the other hand, indoor vegetable farming allows you to completely control the environment and grow your crops year-round.

Eco-Friendly – Starting an indoor vegetable garden is good for the environment. There’s a lot of transportation involved in getting vegetables to the supermarket, particularly when out-of-season items are shipped halfway across the world.

Save Time and Money – Having an indoor vegetable garden allows you to make fewer grocery trips, saving time and also money.

Soil Requirement for Indoor Vegetable Farming

For growing vegetables, your soil should include plant or animal compost and fertilizers, as well as equal amounts of perlite and vermiculite to assist in the retention of air and water. If you set up your soil correctly, you must be able to grow your indoor plants all year long. Healthy, rich soil is the key to successful and productive vegetable farming. A soil test will give you an idea of your existing soil fertility and pH level, and offer suggestions of what types of fertilizers or amendments will get your plot.

What Do You Need to Grow Vegetables Indoors?

All vegetable plants need light, water, and nutrients. Vegetables need specific care if you want them to flourish, but the basic needs are generally the same. If you don’t have ample natural light in your house, you can invest in a grow light. Also, you will need to decide where and how you’ll be planting your vegetables. There are several ways to set up your indoor vegetable farm. Once you’ve assessed how much light and space you have available you can decide how best to build your vegetable garden.

Space and Lighting Conditions for Indoor Vegetable Farming

  • Choose the Right Grow Lights – Not all lights are the same. Vegetable plants respond to different color lights. Usually, grow lights sold on the market are either red (yellow) or blue (white).
  • Blue lights encourage compact, bushy growth.
  • Red lights help the plants create blooms. Orange and red color lights tend to generate more heat.
  • There are several different types of grow lights aside from their colors. The lights change in price and how well they perform. Most grow lights need hung from the ceiling or attached to your wall.
  • How much available space you have will influence how your indoor vegetable garden takes shape. It requires some creativity, shelving, or even a trellis to keep your garden footprint as minimal as possible. Something else to be aware of is being able to give your vegetable plants an ample amount of light. Direct sunlight is essential for an indoor garden.
  • A sunny window in your kitchen is perfect for a vegetable garden. An LED light can make a world of difference to your vegetable plants and help them thrive inside just as much as they would outside.

Indoor Vegetable Farming Tips for Best Success

Select a Right Pot or Containers

The pots you can use for indoor vegetable farming should be large enough to offer the roots of the plant ample room to grow. Since vegetables won’t be growing in the ground, you need to make sure your pots offer enough room for them to grow. Also, your indoor vegetables need well-draining soil.

Make sure your containers have holes in the bottom so the excess water can drain out. If your pots or containers don’t have holes and you worry that drilling holes might break the pots, you can place a layer of rocks in the bottom of the pot before adding the soil. If pots do have holes, make sure you have a drainage container under the pot so the water that drains out doesn’t damage your floors. To start, find a pot that’s large enough for the roots of your plant to grow, that also has a drainage hole in the bottom.

Once you have your pots or containers, it’s time to get the right soil. You want to pick out the indoor potting soil, which is formulated to give plants the nutrients they need but won’t get since they’re not outside.

Provide the Right Amount of Light

Most vegetables to grow indoors need a fair amount of sunlight and warmth throughout the day. If you have some windows that get a lot of suns, you can place pots there. Though, if they won’t get enough light from your windows, you can get some grow lights. These specialized lights give your vegetable plants the optimal light they need to grow, no matter what the conditions are like inside or outside.

Light is very essential for indoor vegetable farming. Indoor plants need plenty of light to grow and especially to produce a healthy harvest. Natural sunlight will reduce how much time you want to run the artificial lights. Your vegetable plants can still enjoy full growth provided with sufficient grow lights.

Choosing the Best Vegetables to Grow Indoors

While you may want to experiment with different plants, it is good to know that some vegetables grow indoors quickly while other plants need a little bit more patience before you harvest. These plants include Arugula, Kales, Lettuce, Broccoli and Spinach, and sprouts such as Carrots, Beets, and Brussel Sprouts among others. Also, these do well in compact spaces and are easy to grow. Also, they love cool environments and moderate light to grow. Other plants like tomatoes and cucumbers take longer and require more space to grow.

Give the Right Amount of Water

The trick to watering indoor vegetable plants is to keep in mind that they won’t dry out as quickly inside as they do outside and you don’t need to water them as frequently. Just make sure the soil stays damp. Generally, vegetable plants need about 1 inch of water per week. One inch must be the total amount of water the garden receives both from rain and you. But, how much water your vegetable garden needs is influenced by your soil type.

Vegetable plants grow best when the soil is damp but not soggy. When plant roots are alternately wet and then dry, it stunts root growth and increases the risk of blossoms dropping off before the product can develop. Carefully check the soil daily by pressing a finger on the top it should feel springy and slightly damp. If it’s dry, it’s time to water.

Harvesting Indoor Vegetables

Usually, vegetables are best when harvested early in the morning.

How to Start Vegetable Seeds Indoors

  • Some vegetable plants like Tomatoes, Eggplants, and Peppers require a long growing season. To ensure healthy plant growth, gardeners start seeds for these vegetables indoors in the spring season. Starting own vegetable seeds is not only less expensive than purchasing transplants.
  • By growing higher quality vegetable seeds will have a higher germination rate and will give you a head-start in growing delicious vegetables.
  • Pots with the seed-starting mix – Seed starting mixes don’t have any actual soil, but they provide ideal conditions for sprouting vegetable seeds. They provide a good balance of drainage and minimize problems with the disease on vulnerable seedlings.
  • Containers have drainage holes – You can use recycled pots, for example, empty yogurt containers but be sure to poke holes in the container bottom for draining, so that seeds are not over-watered.
  • Plant seeds at the proper depth – Carefully check the seed packet for planting depth. The rule of thumb is to plant the seed 2-to-3 times as deep as the seed is wide. For example, tiny seeds must be barely covered by soil mix, while large seeds like beans should be sown about an inch deep. If you sow vegetable seeds too deeply, they won’t have enough stored energy to make it to the surface.
  • Vegetable plants that are best started indoors include broccoli, Brussels sprouts, cabbage, lettuce, and tomatoes. Those with a slower root development such as cauliflower, celery, eggplant, and peppers, should also be started indoors.
  • Keep seed-starting mix moist – Vegetable seedling roots need both air and water. As soon as seedlings emerge, and then place pots in a bright location.
  • Cool room temperature is best for seedlings. Though, finding a cooler room in the house or garage, while still maintaining a good light source, will help them thrive. At higher temperature levels, seedlings may get leggy.
  • Begin fertilizing weekly – Use a half-strength fertilizer once your vegetable seedlings have one or two sets of leaves. Organic fertilizers are a good choice since the plants provide a range of nutrients, including micronutrients.

Ideas for Indoor Vegetable Farming

Growing Vegetables Hydroponically

Hydroponics farming is the process of growing plants without soil. You will need a good lighting system and a timer for a hydroponic garden. A fluorescent light fixture purchased at the hardware store that can hold 2 tube light bulbs supplies plenty of light for your hydroponic garden. And, add a timer to the system so the lights go on and off automatically. Knowing the pH level of your water is essential for growing vegetables. To obtain the best yield, you’ll want to give vegetables the optimal growing environment. A range of 5.5-6.5 is suitable for most vegetable plants. Vegetables of indoor Hydroponics are Spinach, Lettuce, Cherry Tomatoes, Cucumbers, Peas, Beans, Eggplant, Cabbage, Cauliflower, and Spring onions.

Vertical Vegetable Garden Indoors

A vertical indoor vegetable garden can be grown using any vertical garden technique. One interesting method to grow your tomatoes, peas, beans, cucumbers, and squash is with the use of a trellis. You can buy trellis or netting. Or you can build your trellis from anything sturdy enough to support your garden. You can easily produce the same amount of fresh vegetable plants without taking up excess space.

Vegetables you can grow vertically in small spaces. The vertical vegetable garden plants are Peas (all three types of peas – snow peas, snap peas, and garden peas), Green Beans, Cucumbers, Pumpkins, Tomatoes, Winter Squash, and Summer Squash. Choose a vertical design that will work best for your space and your needs. The Garden Tower is the best vertical gardening system for growing vegetables because it has a lot of features. Place the support system in the garden or on your patio before planting vegetables.

Organic Indoor Vegetable Farming

Organic vegetable gardening means gardening without man-made chemicals. Instead of synthetic ingredients, organic growers rely on ingredients that occur naturally and that work in harmony with the natural goodness that comes from healthy and productive soil. Organic gardening has many levels. For a healthy organic vegetable garden, you need to start with healthy and organic soil. The most important component in the soil is the organic matter like manure, peat moss, or compost, which is the best option because it contains decayed microorganisms of previous plant life.

To start an organic vegetable garden, choose a suitable spot where you can dig a plot, build a raised bed, or set up planting containers. Then, prepare your soil and plant your veggies. As your plants grow, keep them healthy by using organic pest control. Organic fertilizer is important throughout the growing season since frequent watering drains nutrients from containers.  Fertilizing vegetable plants will help them grow faster. Different types of organic fertilizer include well-rotted manure from plant-eating critters like rabbits, horses, sheep, and chickens, prepackaged organic fertilizer bought online, or at your local garden center. Also, you can find different organic fertilizers at garden centers and home improvement stores.

Secrets to Start Vegetables Indoors

  • The key to successfully growing vegetables indoors understands how much light it needs to thrive. Different places in your home will offer up varying levels of natural light and the average windowsill can support low- to medium-light loving plants. To germinate seedlings or grow high-light edibles, such as cherry tomatoes, you’ll need to boost your light levels with grow lamps.
  • You can use traditional planters and pots, but plastic storage tubs, boxes, and other items work just as well. Whatever container you select, there must be drainage holes. Make sure you pay attention to what your plant needs and some plants require large containers than others.
  • Growing vegetables is a great way to ensure you have healthy foods for your favorite recipes.
  • A home gardener has a distinct benefit of harvesting a vegetable at its peak quality.
  • Vegetables attain their best eating quality when allowed to ripen on the plant, but this peak quality is reached before the vegetable is fully mature for example Cucumbers, Squash, Okra, Sweet Corn, Peas, and Beans.
  • If vegetables are not easily removed when twisted or pulled and then use a knife, scissors, or hand pruners. These tools help prevent the tearing or breaking of a plant, which can lead to disease infection. Be careful not to step on the stems of the plants while harvesting.

The Best Plants for Indoor Vegetable Farming


Carrots are one of the best vegetables to grow in a pot indoors. While the plants don’t need a lot of room above ground, they do need large containers that let them grow deep. Shorter carrot varieties need a pot at least 8 inches deep and longer varieties need 12 inches to reach their full size. Select a moistened organic potting soil mix and fill your container up to an inch from the top. Plant your seeds about 1/4 inches deep.


Radishes are fast-growing vegetables. Some varieties are ready in less than 3 weeks. Radishes don’t need as much root space as carrots, and they are a great addition to those salad greens.

Kale is a great vegetable to grow indoors. Like arugula, you can harvest the kale bigger leaves and leave the small ones for a later harvest. Plant a few kale seeds in a medium-size pot and cover with 1/2 inch of soil. Once a garnish and now a superfood, the kale plant is a great vegetable to grow indoors.

Problems with Indoor Vegetable Farming

Vegetable Seeds not sprouting

Reasons – The vegetable seeds are not good; they’re too old; you have been watering them too much or too little; they are buried too deep in the soil or the temperature level is not conducive to growth. The common reason for them to not sprout is because old seeds have been used or you have watered them too much.

Leaves drooping or turning yellow

Reasons – Vegetable plants are thirsty for water or are deficient in a mineral that they need. Dry soil and drooping leaves are the most visible signs of the plant being thirsty for water. How much water your plant needs mainly depends on the type of pot you use, the type of soil, the sunlight and temperature that the plant is exposed to, and the amount of water it gets. Adjust your irrigation so that your vegetable plant is adequately watered not too much and not too little.

Leaves turning yellow can be a sign of overwatering, insects, or too much sunlight. Keep adjusting these water levels. Healthy plants look lively.

Flowers dropping without growing into fruits

Reasons – No pollination or lack of nutrition. Though, flowers will need to be pollinated to develop into fruit. If wind and insects are not available for this function, you can aid pollination by shaking the flower stalks or even by transferring pollen by a small soft paintbrush from stamen to stigma. Vegetable plants need air circulation. A draft from the air-conditioner or a fan cannot substitute and can harm the plant too.

Diseases and pests

Like outdoor plants, bacteria, fungi, viruses, and pests can create problems with indoor plants. Aphids and whiteflies can be mainly troublesome when gardening indoors.

Solution – Inspect vegetable plants regularly and then treat them immediately to avoid heavy infestation or spread of disease.

One of the benefits of gardening indoors is the lack of common outdoor garden pests like aphids and caterpillars. Though, the same garden pests that affect indoor houseplants may also bother the indoor vegetable garden. The insects are very easy to remove with a small vacuum.

Mealybugs occasionally affect indoor vegetable plants. Kill the white fuzzy pests by using a cotton swab saturated with rubbing alcohol.

Spider mites are a common problem in indoor plant pests, especially in dry conditions. Water the entire plant, not just the soil, because mites dislike moist conditions.

Bacteria and Infections

Indoor vegetable gardens are susceptible to disease and infections, no matter how well you look after them. There are some fungicides and organic solutions that you can utilize to keep vegetable plants healthy if you suspect an infection.

Improper Watering

You can give plants too much water, and you can dry out plants by giving them too little water. Your indoor plant needs just the right amount of water to do well. If the plant leaves are decaying, you’re giving too much water to the plant. Make sure the containers have drainage for the excess water to escape. Also, you can try adding small-sized rocks to the container before adding soil.
