When you think about the word 'garden', you start having a vision of a small tilled patch of soil that has beautiful flowers, aromatic herbs, and fresh vegetables. 

Or you might start thinking about rows of lettuce, corn, tomatoes, etc., sprouting out of the ground proudly. Thought of that huge greenhouse with plastic pipes and covers might also cross your mind!

You can grow plants without soil. Researchers have discovered that soil is merely a medium that contains the essential nutrient solution for adults to consume and grow. Therefore, it is not mandatory for the growth of plant roots. 

The key here is to provide your plant with a variety of nutrients and minerals. These include phosphorus, potassium, and nitrogen. If you can add these ingredients into your plant's water supply, the soil will no longer be necessary for growth. 

No matter what types of vegetables you want to grow, we'll guide you on how to grow vegetables indoors without soil. 

Can You Grow Food Without Soil?

Growing vegetables indoors won't require soil, and you can keep growing throughout the year as well. It also allows you to overcome any space constraints with the help of hydroponic gardening.

Hydroponics is a kind of gardening technique that involves the usage of water instead of soil. The roots of a plant remain submerged in water containing nutrient solution. The water level is kept right where the soil level would have been if you planted the plant in the soil.

Growing vegetables with hydroponics are healthier because there are no chances to develop soil-borne pests, bacteria, or weeds. You can use hydroponics to grow your favorite veggies year-round. If you are thinking about growing vegetables in your home garden in an unusual place, this is the technique you need to adopt.

Whether you have space constraints or inappropriate conditions to grow anything, with the help of a hydroponic system, you can easily grow vegetables at any time of the year as well.

What is a Hydroponic Garden System?

hydroponic garden

An indoor hydroponic system is all based on water and doesn't require any soil configuration for the plants to grow. With research and development in gardening, it has been discovered that soil is not mandatory for plants. 

The nutrients and minerals present in the soil are essential for the plants' growth. Therefore, the soil is just playing the role of a medium to distribute the nutrient solution. Instead of soil, water can be used as a medium if it contains the same amount of minerals and nutrients required by the plants.

Thus, the method of the hydroponic garden system came into existence. Most plants can even grow in the water independently with just a little assistance from the sunlight. This way of growing brought a revolution that made sure fresh produce is available regardless of the season.

A hydroponic garden system is usually not that big, and you can fit it in tight corners as well. There are also grow cabinets you can use which are a bit bigger. These days, you can grow from your kitchen window or counter, and it looks nice as well. 

Benefits

1. Easy To Set Up And Manage

One of the primary benefits of a hydroponic garden system is that it is straightforward to set up and manage. You are not dealing with soil and need to make a solvent with water with nutrient solution (plant food). You will only have to plug in your grow cabinet or tent and create the right conditions for your plants to grow.

2. Smaller Footprint

There are different options available when it comes to growing indoors. And the best thing about growing indoors is you can easily choose the right size of footprint according to the space available in your home. It can be as small as your drinking glass or as large as your entire closet. And then, of course, you have the option to grow tents as well, which are even bigger. 

3. Automation and connectivity

With the development of technology, these grow tents and grow cabinets are evolving as well. The current models are equipped with more connectivity options and automation. Some models come with Wi-Fi connectivity, and you can use a mobile application to automatically alter the conditions from remote locations based on the plant growth stage. 

Most of the new models of these cabinets and tents are coming with automation, and they don’t need much input from you. It adds to the overall user convenience and makes indoor growing even easier and more fun.

4. Full control over conditions

These grow cabinets and boxes that one can use for an indoor vegetable garden put you in control of the situation. No matter what time of year it is, you can alter temperature, moisture, and light to increase or slow down the growth process. 

You can either go for natural sunlight that comes from your windows or go for artificial light systems. There are plenty of options available for your indoor vegetable garden. 

What Do You Need to Set Up Your First Vegetable Indoor Garden?

If you are ready to jump into gardening, you will have to keep in mind that it will be a lot more daunting in the beginning. You might be thinking right now that maybe you should have given it a second thought and not have decided to go with indoor gardening. 

But it is not as difficult as outdoor or traditional gardening. You will only have to take time from your busy schedule for the plants to change the water with nutrient solution. Moreover, you might have to change the light conditions at different stages of a plant’s life cycle. 

You can start by growing some plants that only need water to grow. We have listed a few above for your assistance. You will need a container filled with water. Just change the water every day or two to keep them growing. Of course, you will also have to place your plants in a proper sunlit area. 

When you think that you have enough experience in growing these small plants, you can increase the number and bring some equipment for assistance. The most important piece of equipment that you will need for indoor growing is a grow cabinet, or a grow tent. Based on your indoor growing needs, you can go for either one.

Grow tents are better suited for indoor growing on a larger scale, while grow cabinets are far more compact than their footprint. They are easy to set up and manage as well. There are some important aspects associated with indoor vegetable gardening. It relies heavily on some key factors, and these are briefly explained as follows:

1. Grow lights 

grow-lights

Some plants need more light as compared to others. In natural conditions, the sun provides the light. But when you are not cultivating outside, you have two options. You can either grow your plants near your window or go for artificial lighting. 

Growing near the windows will get your plants the much-needed sunlight. But with the help of grow lights, you can go for artificial lighting and provide your plants with close-to-natural lighting. 

There are two different types of grow lights as well. You can go for cool spectrum lights or hot spectrum lights. Lights with a warm spectrum have low numbers on the scale, and they are usually around 3000K. This light is suitable for tomatoes, cucumbers, and various other fruiting plants. 

On the other hand, cool spectrum lights have high numbers on the scale, and they are around 6500K. Cool spectrum lights are better suited for leafy vegetables and seedlings. And there are different types of grow bulbs as well. There are fluorescent bulbs, LEDs, and incandescent. 

Most people go for LEDs because they are cost-effective, and they consume less energy as well. You might find them a bit experienced upfront, but they do tend to last very long. A grow cabinet can prove to be a good option because these grow cabinets and grow tents have grown lights in them. Read here our best grow tent list for 2021.

2. Temperature

Temperature variations can influence plants just like humans. And any sudden changes can harm the growth of your plant. The best temperature range for any plant to grow is around 70F to 75F. Most grow cabinets and grow tents come with inbuilt thermometers to alter the temperature based on the plants you are growing. 

You can also use your central air conditioning to make the temperature suitable for the indoor plants without using these grow tents or grow cabinets. But you don’t have to be exact with this temperature range and use it as a reference. 

3. Moisture

hygrometer

If you are using an indoor grow cabinet or grow tent, most of them come with an inbuilt hygrometer that will tell you about the current moisture conditions. It will be a good help for you to maintain the right conditions that are ideal for the plant you are growing. 

Most of the grow cabinets and tents can maintain moisture levels themselves. If you don’t know anything about this metric and learn anything about it, you should go for an automated grow box that can self-regulate. 

4. Growing medium

Growing medium refers to soil because you cultivate your plants in that. In terms of indoor growing, there can be different growing mediums. Most people go for the soil because it is more forgiving and stay right on top of your plants all the time, and keep an eye on them to see the results. 

In the case of hydroponics, or growing in water, you need to be a lot more careful to see the positive results. Apart from water, there are other soilless mediums, including gravel, coco coir, clay, perlite vermiculite, and peat moss soil.

Tips for a Successful Vegetable Garden

grow what you like

You have to keep in mind various points if you want your indoor garden to be successful. It might seem a pretty simple task, but you need to follow these tips carefully if you want to grow successfully.

1. What if you don’t know how to grow vegetables indoors without soil? 

You don't need to expect so much of yourself right in the beginning. If you don't have any indoor gardening experience and starting fresh, try to do everything as an experiment. And don’t expect a supermarket quality produce right from day one. You won’t be able to control different vegetable cultivation in one go either. 

Plus, you can grow a few crops within a few weeks, especially radish and salad leaves. But most of them will take months. The good thing is you don’t have to worry about any pests. You can always ask around for assistance from anyone who has some experience with gardening or search online for tips and more help. 

2. What if you don’t have any vegetable plant seeds? 

If you don't have any seeds and don't want to buy and waste your first lot in experimenting, don't worry. You already have plenty of seeds to grow right in your kitchen. Use the vegetable plant seeds from the vegetables that you already have in your refrigerator. 

A pulp of tomato or seeds from the pepper, coriander, fennel, dill, or even fenugreek. Dried peas can help you grow pea shoots. There are various other vegetables you can use to grow your garden. Make sure to grow the plants that you can identify very easily and work on your knowledge. 

3. What if you don’t have soil? 

You can always go for various soilless mediums for growing your indoor vegetation. And the best one of them all is the water-based hydroponic system. 

You will only have to use nutrients and minerals for your parents and make water solvents with them. With grow tents and grow cabinets, you can conveniently grow your plants without using soil. This way, you won't have to deal with any pests or bacteria either.

4. What if you don’t have any space or garden? 

You don't need to have a lawn or any extra space for it. You can use small pots (rock wool cubes), glasses, jars, and even buckets for this purpose. Rock wool cubes are best because they contain your plant quite well. 

As they are small, you can place them anywhere in your window, on your kitchen counter, or anywhere else you prefer. But a better way of proceeding with this matter is to go with a grow box or cabinet. That will allow you to conveniently grow indoors even if you don't have much light available. 

5. Make sure to start small

If you don't have any experience in growing, then make sure you start small. With a small space to cover, things will be a lot more manageable for you. Also, confirm you don't expect too much from your garden right in the beginning. Take small steps and ensure you advance and learn continuously. 

6. Grow what you like the most

When working on your favorite type of vegetable, you will work on it with more interest. You can grow something that you or your family love to consume. If the consumption is high, you must prioritize the growth of that particular vegetable. 

7. Go for successive crops 

Growing both warm and cold weather season vegetables will allow you to harvest veggies right through the year. You can start with lettuce, greens, carrots, radishes, and broccoli. When you're done with your cold-weather crops it's time to go with the warm-weather crops like peppers, tomatoes, herbs, and eggplants. In fall, you can start cultivating kale, cabbage, and potatoes. 

8. Cultivate vining crops for better yield 

When you choose vining crops such as peas and green beans, you are using your available vertical space. Therefore, you are increasing your yield per square foot. 

Conclusion

There you have it. Now you know how to grow vegetables indoors without soil. You don’t need soil to grow vegetables or grip your indoor vegetable garden. There are plenty of other options available for you, not just in terms of methods but in terms of tools as well. And the easiest one of them all is hydroponic gardening, which involves growing in water. 

Plants will consume the nutrients and minerals that are in the water-based solvent. You can easily alter the conditions based on the needs and requirements of the plants. Furthermore, you can boost or slow down the growth process as well. 

You can grow vegetables indoors without soil with the help of the right nutrient solution, accurate water level, and grow cabinets or boxes. They put you in control, and you can easily change the literature, moisture, and light conditions. Some of these hydroponic chambers also come with a separate compartment for cloning and vegetation with a separate air chamber for each. 

They allow you to utilize the minimum available space effectively and don't need much input from you because of their automated features. Now, you know how to grow vegetables indoors without soil.
