Do you have a heart for gardening? That feeling of getting in touch with nature, growing plants on your own, and seeing them bear fruits (or flowers)? Well, I do cause it’s fascinating! But then, you moved into the city and space is just so limited for building a garden. No problem because with general hydroponics, you can practice your green thumb and make your home garden flourish. In this guide, I’ll tell you everything you should know to get started. Let’s dive right in!

What is Hydroponics?

So, what’s this so-called ‘Hydroponics’? Let me put this simply for you. Hydroponics is a way of growing plants without soil, only by nutrient solution water. The term itself is derived from the Greek words “hydro” (which means water), and “ponos” (which means labor). It’s basically letting water (not just plain water but with essential nutrients) do all the work for you. Cool isn’t it? No need to get your hands all dirty in the soil.

Hydroponics has many benefits, such as faster plant growth, bigger harvests, and using less water than traditional gardening. It also reduces the need for harmful chemicals, leading to healthier plants. To find out more about the benefits of hydroponics, you can read this NCBI research article and this article from Harvard SITN Flash.

Benefits of Hydroponics

Now let’s talk about the benefits and why you should try this method. Just to be clear… I don’t have any issues with traditional gardening. I mean, we all started from there, right? But there are plenty of compelling reasons to embrace hydroponics. For example, you dream of having a ‘mini indoor garden’ but you lack the space and you’re not good with growing plants from soil. With general hydroponics, there’s a bigger chance of success for your plants and they grow faster too. Especially if you use general hydroponics nutrient solutions because they provide just the right mix of minerals for your plants. Why? Because nutrients are delivered straight to their roots in the water. Which means higher yields than traditional soil-based gardening. Plus, with hydroponics, you have total control over nutrient levels, pH, and light exposure. Oh, did I mention that it’s a space saver too?

Different Types of Hydroponic Systems

1. Deep Water Culture (DWC)

First on our list is DWC (Deep Water Culture). In DWC, plants’ roots are soaked (dangling down) with nutrient-rich water, getting all the nutrients they need. It’s simple, effective, and perfect for newbies (that have no idea what they’re doing) testing the hydroponic waters.

2. Nutrient Film Technique (NFT)

The Nutrient Film Technique might sound complicated, but it’s basically a gentle stream of water flowing over the plant roots. Unlike DWC, roots aren’t soaked here. A thin stream of nutrients keeps them fed and happy, making it a go-to for growing lightweight, leafy greens (like lettuce).

3. Ebb and Flow (Flood and Drain)

Close your eyes and imagine tiny ocean tides watering the roots of your plants. Yeah, that’s what the Ebb and Flow system looks like. The roots get a periodic soak in nutrient-packed water and then a breather, which keeps them oxygenated. It’s a super flexible system that works for tomatoes, peppers, or even lettuce.

4. Drip Systems

Think of Drip systems (also known as ‘active hydroponic systems’) like the irrigation experts of hydroponics. With its micro irrigation system, small emitters in the tubes deliver nutrient-rich water directly to your plants. This method is ideal for larger plants, like wine grapes and tomatoes, and is a favorite in commercial setups.

5. Aeroponics

Last but definitely not the least is Aeroponics. In this system, plants grow in a mist environment without using any substrate. How? Roots are hanging in tha air and get misted (or sprayed) with a nutrient solution regularly. Although it sounds cool, it does require a bit more technical know-how to get up and running.

Essential Components of a Hydroponic System

1. Water Reservoir

The water reservoir is the heart of your hydroponic system. After all, it’s called ‘hydroponics’ for a reason. Make sense? This is where your nutrient solution is stored, feeding your plants everything they need. Make sure it’s big enough to hold plenty of water for your setup.

2. Growing Medium

Yeah, I said we don’t need soil to grow plants here but still, your plants need something to cling to. That’s called ‘growing medium’. Common options include rockwool, coconut coir (my personal favorite), perlite, and clay pellets. Each provides support and helps anchor the roots.

3. Nutrient Solution

The nutrient solution serves as your plants’ food and multivitamins so they’ll grow fast and healthy. A well-balanced hydroponic nutrient mix just like General Hydroponics FloraGro will provide all the essential minerals your plants need to flourish. But please, make sure to choose a solution that’s suited to the specific plants you’re growing.

4. Air Pump and Air Stones

Just like us human beings, plants need oxygen to thrive. An air pump paired with air stones helps oxygenate the water, keeping the roots healthy and full of life. Plus, these air pumps push the nutrients from the reservoir onto the plants.

5. pH and EC Meters

Lastly, you need to monitor the right pH of your nutrient solution. Too high or too low can really harm your growing plants. So, get a pH and EC Meters to make sure they’re getting just the right balance of pH levels. Monitoring the pH levels of your nutrient solution is a must.

Getting Started with Your Hydroponic Garden

1. Choose Your System

Ready to get started? Choose a hydroponic system that aligns with your needs and space. If you’re just getting started, DWC or Ebb and Flow systems are excellent choices for beginners. Simple and easy!

2. Select Your Plants

Now what do you want to grow? Lettuce, spinach, or tomatoes? If it’s your first time, spinach, and herbs are perfect. Once you’ve gained some experience, you can branch out to more complex plants like tomatoes, cucumbers, and peppers.

3. Set Up Your System

Set up your hydroponic garden in a well-ventilated area with plenty of light. No access to natural light? That’s fine. Use grow lights (or artificial lights) instead. Just make sure they’re suitable for the type of plants you’re growing.

4. Mix Your Nutrient Solution

Follow the instructions on your nutrient solution package to mix it correctly. Fill your water reservoir and check the pH and EC levels to ensure they’re within the optimal range for your plants. If you’re not sure Google it. You can do this!

5. Plant Your Seeds or Seedlings

With your system set up and your nutrient solution ready, it’s time to plant! Place your seeds or seedlings in the growing medium (coco coir, rockwool, etc), ensuring the roots are in contact with the nutrient solution.

6. Monitor and Maintain

Keep a close eye on your hydroponic garden. Regularly check the pH and EC levels, top up the water reservoir as needed, and be vigilant for any signs of nutrient deficiencies or pests.
