What Is Hydroponics?
Hydroponics is a type of gardening that doesn’t use soil. Instead, it uses an inert medium like sand or gravel to grow plants in a liquid solution of nutrients.
The term “hydroponics” can refer to several different types of gardening methods:
- Hydroculture: This method uses water as the growing medium and nutrients added to it.
- Aquaculture: This method is used for cultivating aquatic animals such as fish or plants underwater in tanks with no topsoil.

Are Plants Grown In Dirt Better Than Those Grown Hydroponically?
You’re probably wondering why soil-grown plants are better than hydroponically grown ones. Well, there are several reasons:
Soil-grown plants are more nutritious. Plants grown in soil contain high levels of vitamins and minerals that can be beneficial to your health when eaten.
In a study published by the National Institutes of Health, they found that “plant-based diets generally contain higher amounts of fiber and antioxidants than meat-based diets.”
This is because the roots of soil-grown plants grow deep into the ground where they absorb nutrients from the earth itself. It also means you don’t need to worry about chemicals being added to your food during cultivation; all those nutrients come right out of natural sources!
Soil-grown plants taste better! We all love flavor — especially when it comes from nature itself! This is why organic produce tastes so good; because it hasn’t been tampered with too much by manmade fertilizers or pesticides (which can sometimes leave behind an unpleasant aftertaste).
Also keep in mind that hydroponics doesn’t always mean pesticide free…
Pros and Cons of Hydroponic Farming
| Pros | Cons |
|---|---|
| More precise control over nutrient delivery | Initial setup costs can be high |
| Faster growth rates | Requires more frequent monitoring and maintenance |
| Higher yields | Increased risk of system failure |
| Can be used in urban environments and small spaces | Increased risk of disease outbreaks |
| Less water usage than traditional farming | Risk of nutrient imbalances |
Are Hydroponic Plants Healthier Than Soil-Grown Plants?
The answer to this question depends on your definition of the word “healthier.” If you think that hydroponic plants are healthier because they don’t get sick as often or have to deal with pathogens as much.
Then yes, they’re healthier. But if you’re thinking about nutrients like iron and vitamin C content then no, not necessarily.
Hydroponic plants don’t have to deal with soil-borne pathogens because they’re grown in a controlled environment where these types of microbes aren’t present.
That’s why hydroponics has become a popular way for medical marijuana growers to grow their crop without worrying about pesticides contaminating their product. However, there are other ways that hydroponics could make your products less nutritious:
- The soil used for growing conventional crops contains minerals such as calcium and magnesium that may be lacking in water-based systems;
- Hydroponically grown foods may also lack certain essential vitamins due to poor lighting conditions;
- Lastly, soil-grown foods can retain more moisture than hydroponic ones (which will be discussed later).

Are There Nutrients Missing From Hydroponic Plants Compared To Soil-Grown Plants?
As you can see, there are some nutrients that are missing from both hydroponic and soil-grown plants.
However, the good news is that with proper supplementation, you can ensure your plants get all they need to grow healthy and strong. There are several ways to supplement your plant’s diet:
- Add an organic fertilizer or supplement with fish emulsion once per week.
- Use potting mix without any added fertilizer when starting new seeds or seedlings.
- Add compost tea made from worm castings every few weeks for nutrient-rich soil.
Which Plant Is Better When Grown Via Hydroponics, Organic Or Conventional?
There is no consensus on which is the superior type of plant to grow. Organic produce tends to be more nutritious, but studies have shown that conventional produce may actually be higher in antioxidants and other beneficial compounds.
Hydroponic plants are usually healthier than conventional ones, as they don’t get exposed to chemicals or other contaminants. However, hydroponic lettuce was found to contain less polyphenols than conventionally grown lettuce. In short: there is no definitive answer here!
Types of Hydroponic Systems
| System Type | Description |
|---|---|
| Deep Water Culture (DWC) | Plants are suspended in a nutrient-rich water solution with the roots submerged in the water. |
| Drip System | A pump drips nutrient solution onto the base of each plant from above, allowing the roots to absorb the nutrients. |
| Nutrient Film Technique (NFT) | Nutrient solution is pumped through a narrow channel, allowing the roots to dangle into the solution and absorb the necessary nutrients. |
| Aeroponics | Roots are suspended in air and sprayed with a nutrient-rich mist. |
| Wick System | A wick extends from the nutrient solution into the growing medium, allowing the plants to absorb the necessary nutrients through capillary action. |
What Are The Advantages Of Growing Hydroponic Plants?
As you can see, hydroponic plants have many advantages over growing your own in soil. It’s important to remember that all of these benefits come from the fact that hydroponic growing has a much lower water content than conventional gardening.
Less water – this is a huge advantage as it means less time spent watering and less money spent on water bills. The lack of soil also means that you don’t need to spend time removing weeds or dealing with pests such as slugs or snails.
Less fertilizer – since there isn’t any soil involved, there is no need to apply fertilizer at all! This saves both time and money on your part (not having to buy fertilizer or mix it up yourself).
While also helping the environment by reducing waste production caused by excess unused nutrients ending up in our waterways via runoff from farms where fertilizers were applied too liberally.”
One important consideration when growing hydroponic plants is the safety of the nutrients used. To learn more about hydroponic nutrient safety, check out our article on are hydroponic nutrients safe explained. You’ll discover the risks associated with hydroponic nutrients and how to mitigate them.
What Are The Drawbacks Of Growing Hydroponic Plants?
There are several concerns you need to be aware of when growing hydroponic plants. The first, and most important, is the quality of your water. Remember that your hydroponics system is a closed loop and whatever goes into it stays there until used by the plant roots or by evaporation.
That means you have to be careful about what kinds of minerals or toxins come into contact with your plants; if they’re present in any amount at all in either the nutrient solution or even just the water itself then they will build up over time and damage your plants.
As an example: potassium can cause leaf burn when it builds up in high concentrations; phosphorus can cause root rot if too much builds up;
Iron (from well water) can cause yellowing leaves; chlorine (from chlorinated city tap water) will kill roots quickly if left untreated but should dissipate after a few days’ use.
The second major concern for hydroponics growers is keeping track of pH levels within their grow systems because pH affects everything from nutrient availability to plant health/growth speed/flowering time etc…
If you’re new to growing hydroponic crops then we recommend starting with somewhere between 6-7 because this level seems to work well for most people (and tends towards slightly acidic conditions).
Does It Take Less Time To Grow Hydroponic Plants Compared To Soil-Grown Plants?
Hydroponic plants grow faster than soil-grown plants. This is because hydroponic systems don’t need to expend energy supporting their weight.
Also, hydroponic plants are less likely to suffer from pest and disease infestations as there are no insects or other organisms hovering around waiting for an easy meal!

How Do You Grow A Healthy, High-Yielding Vegetable Garden Using Hydroponics Indoor And Out?
There are many different types of hydroponic gardens. Here is a list:
- Indoor hydroponic gardens, you can grow these on your kitchen countertop or in window boxes.
- In outdoor hydroponic gardening, you can grow these in your backyard, but be careful with the local ordinances about what you’re allowed to grow in public parks.
- Greenhouses, if you have one already, there are ways to make it into a hydroponics greenhouse! Or if not, check out this book on how to build one yourself at home!
- Closets, if you’ve got access to an unused closet near the kitchen or bathroom sink (or even better: both!), then this is a great place for some indoor hydroponics gardening!
Do I Need Special Equipment Or Watering Systems For Growing My Plants In Soilless Gardening Methods Like Hydroponics, Aeroponics, And Aquaponics?
Hydroponics and other soilless gardening methods are easier to get started in than you might think. You will need some equipment, like a water pump, nutrient solution, and bulbs for the light source. The following is an overview of what you can expect to purchase when starting:
Water Pump: A good-sized pump will run about $100 at your local home improvement store.
Water Reservoirs: A large reservoir of 5 gallons or more is recommended for each plant (the bigger the plants, the bigger the reservoir).
Nutrient Solutions: Mixing up nutrient solutions isn’t hard but does require some attention to detail (e.g., measuring pH) because too much or too little of certain nutrients can cause plant problems.
You can buy premixed nutrient solutions or make your own using quality ingredients from companies like General Hydroponics® or Botanicare® .
Lights: LED grow lights are easy on power consumption while providing intense light that’s ideal for growing plants indoors during cold months when sunlight may be limited outside due to shorter days as well as cloudy weather conditions that block sunlight altogether!
They also come with adjustable height options so you can find one that fits perfectly inside your chosen grow tent size.* Tents & Containers:
There are many types available but we recommend choosing one made specifically for hydroponics systems since they provide better insulation than regular tents do.”
Hydroponics Might Be The Future Of Farming
Hydroponics is the process of growing plants in water and nutrients. This method has been around since the early 1900s.
But it has recently garnered a lot of attention as more people discover how efficient and easy it can be to use hydroponics for growing fruits and vegetables. In fact, some companies have even started using this method to grow food on Mars!
Significant benefits of hydroponic gardening include:
- Less soil needed – only enough space required for your plant’s roots to grow
- Less time spent watering plants (you don’t need to give them so much water)
