3. Soil Not Required in Hydroponics

Hydroponics is all about growing plants without any soil. Instead, you provide water, oxygen, and nutrients to help hydroponic plants flourish. This means you can grow them anywhere – inside or outside. It’s a soil-free gardening approach that’s versatile and easy.

This is truly mind-blowing when it comes to hydroponics facts.

4. Electricity is Must

Unlike traditional gardening which relies on nature and occasional watering, hydroponic setups usually require electricity. Electricity powers pumps to deliver water, nutrients, and oxygen, promoting healthy plant growth.

A power outage can swiftly affect your plants, so keeping an eye on electricity and responding promptly is crucial.

5. Type of Water Matters in Hydroponics

Not all water is the same for plants. If you thought tap water, rainwater, or bottled water would work, think again. In places with hard water, there are too many dissolved minerals, making it tricky for hydroponics.

The issue is that there’s a limit to how much nutrient solution hydroponic plants can handle. If your water has lots of calcium and magnesium salts, the essential nutrients for your plants might get left out. Different plants need different nutrient concentrations, and hard water makes it tough!

But don’t worry! You can mix your tap water with sterile water or use filters like reverse osmosis or activated carbon to remove some or all of the dissolved solids. This makes even the hardest water suitable for hydroponics.

6. Hydroponics has Many Forms

Hydroponics comes in various forms, not just one. There are at least 6 or 7 main types and many more variations. The most common ones include the Wick System, Drip Hydroponics, Ebb and Flow, Water Culture, Nutrient Film Technique (NFT), and Aeroponics. Each has its unique way of nourishing plants without soil, offering flexibility and options for different growing needs.

7. Hydroponic is for All Budgets

Hydroponic systems can be as cheap or as expensive as you want them to be. Many people think it’s an expensive hobby, but the truth is, that you can create a simple system for less than $50 using easy-to-find items. You can even make a basic wick system from an empty soda bottle at almost no cost.

On the other hand, if you’re willing to invest, you can spend over $10,000 on a pre-built aquaculture system that can provide enough food for a big family throughout the year.

Don’t let the idea of cost stop you from trying hydroponics. Starting small with a DIY approach is a wallet-friendly option. There are plenty of online plans and tutorials that make setting up a home system a lot easier than you might think.

8. Plants Can be Grown All Year Round

Hydroponics is perfect for year-round plant growth indoors. By using grow lights, you can give plants the light they need, making it possible to cultivate them throughout the year.

Picture harvesting fresh fruits and veggies from your indoor hydroponics system whenever you want. While it might not save you tons of money, it offers the convenience of knowing exactly where your food comes from.

9. Plants Grow Faster in Hydroponic

Hydroponic plants get everything they need directly, making growth easier compared to soil-based plants that have to search for water and nutrients. In hydroponics, nutrients are delivered to the plant, ensuring optimal nutrition without limitations.

This efficient process allows plants to grow 30 to 50% faster than those in soil, resulting in more abundant harvests. It’s fascinating that growing without soil can speed up plant growth, and this is a standout benefit of hydroponics.

10. Plants Grow Up to Twice Their Size

With hydroponics, your fruits and veggies can grow up to twice their size, thanks to the efficient growing conditions. Whether it’s tomatoes, strawberries, peppers, or lettuce, they all have the potential to be considerably larger and taste delicious compared to when grown in soil.

11. Plants are Healthier

Hydroponic plants stay healthier and get sick less often, so you don’t need many, or sometimes any, pesticides. When plants grow in fields with pesticides, some people worry about their health. With hydroponic plants, this worry is much less because they usually don’t face that problem.

12. No More Weeding Hassles

When you use hydroponics, there’s no need to deal with weeds. As a gardener, it’s frustrating to see weeds pop up shortly after making your flower beds look perfect. With hydroponics, you won’t have this problem, making gardening easier without the task of weeding.

13. Your Plants, Your Rules

Hydroponics lets you be the boss of your plants’ growth. You can control everything – water, nutrients, temperature, oxygen, humidity, and light. It’s like having a remote for your plant’s world, and you can set it just how you want.

If you’re growing a few herbs at home, you can keep it easy. But for serious home or business hydroponic growers, tweaking every detail helps get the best plant growth and more produce.

14. Hydroponics for Science Lovers

If you’re into experimenting, hydroponics is perfect. You can buy premade nutrient mixes or mix your own using individual elements. This way, you have full control to pick nutrients that suit your plants or specific growth stage. It’s like being a scientist for your plants, finding the best mix for the biggest harvest.

15. Essential Nutrients in Hydroponics

In hydroponics, the grower has to give everything plants need to thrive. Unlike soil, where plants can use the nutrients already there, hydroponic plants rely on the grower for everything. Even if you add fertilizer to the soil, it usually only contains the main nutrients like nitrogen, phosphorus, and potassium.

In hydroponics, you need to provide all the nutrients, including the tiny ones like iron, zinc, copper, and molybdenum. If you don’t, your plants might face health issues. Check out this guide for more on hydroponic nutrients.

16. Monitoring is Required

In hydroponics, it’s crucial to watch over your system, especially the temperature, pH, and nutrient levels, to keep your plants healthy.

Plants can get stressed or even die if their environment suddenly changes. The pH of the nutrient solution matters a lot because different nutrients are absorbed at different rates. This can lead to nutrient problems, and it’s not always easy to figure out.

Unlike soil, which acts as a buffer, hydroponic systems can see big changes in nutrient levels and pH over time. As plants use water and nutrients, and water evaporates, the solution changes. So, you need to check and adjust your system often to make sure your plants stay healthy.

17. Hydroponics on Cosmic Missions

NASA and other space agencies are big fans of hydroponics because it’s a top choice for growing food in space. In space, there’s no soil, and weight is a major concern for launching missions from Earth. Hydroponics is perfect because it doesn’t need soil and uses 90% less water. This makes it ideal for astronauts who might have to grow their food on future space missions.

It’s pretty cool that when I’m working on my hydroponics system, I can say I’m following in the footsteps of astronauts!

18. Fish and Plants Live Together

Aquaponics is a cool twist on hydroponics where fish and plants grow in one system. The waste from fish gives plants the nutrients they need. Plants and helpful bacteria clean the water, keeping the fish happy.

It’s like copying the natural cycle in ponds. Managing aquaponics can be easier because you can find a good balance with only a few tweaks now and then. However, since fish and plants like different conditions, you need to find a middle ground. This compromise can affect plant yields and limit which fish and plants can grow together successfully.

19. Compact Growing with Hydroponics

Hydroponics lets you grow plants close together without competition for resources, unlike in soil. The plants get a direct supply of nutrients, water, and oxygen. In the same space, you can grow up to four times more plants compared to traditional soil methods. This makes hydroponics perfect for small spaces or when space is limited. Urban areas, where space and soil are scarce, really love hydroponics.
