Is General Hydroponics Organic – An Aquarist’S Guide To Aquaponics

Written ByHoward Parker

Have you ever looked at your aquarium, teeming with life, and thought about the sheer amount of nutrients cycling through it? You diligently perform water changes, pouring that nitrate-rich “waste” water down the drain or maybe on a few houseplants. You’ve probably also heard of hydroponics and seen brands like General Hydroponics, wondering if you could use them to supercharge plant growth.

It’s a common thought for conscientious aquarists who want to create a more sustainable, natural ecosystem. This leads to a crucial question many people ask: is general hydroponics organic?

I’m here to tell you that not only will we answer that question definitively, but I’ll also show you how to unlock a method of growing that is truly organic, using the very aquarium you already love. We’re going to bridge the gap between your fish tank and a thriving, soil-free garden.

In this guide, we’ll dive into what “organic” really means, look at General Hydroponics products, and then explore the incredible world of aquaponics—the ultimate way for an aquarist to create an eco-friendly, productive paradise. Let’s get growing!

What Does “Organic” Actually Mean in Gardening and Hydroponics?

Before we can tackle the main question, we need to be on the same page. The word “organic” gets thrown around a lot, but in the world of gardening and agriculture, it has a very specific meaning.

At its core, “organic” means that the nutrients and materials used are derived from once-living organisms. Think of things like compost, manure, fish emulsion, and bone meal. These materials break down over time, releasing nutrients for plants to absorb.

This is where the world of traditional hydroponics often diverges. Many hydroponic systems rely on pure, refined mineral salts that are immediately available to the plant roots. While these minerals are the same elements plants get from organic sources (like nitrogen, phosphorus, and potassium), their synthetic or highly processed origin means they don’t meet the strict definition of organic.

The “Certified Organic” Standard

For a product to be labeled “USDA Organic” or be listed by the Organic Materials Review Institute (OMRI), it must meet stringent standards. These standards typically prohibit the use of synthetic fertilizers, pesticides, and genetically modified organisms (GMOs).

The debate about whether hydroponics can be organic is a hot one, but for our purposes as aquarists, there’s a much clearer and more natural path forward.

Synthetic vs. Natural Nutrients: A Quick Breakdown

Think of it like this: synthetic nutrients are like giving a plant a vitamin pill—a direct, concentrated dose of exactly what it needs. Organic nutrients are like giving a plant a whole, balanced meal that needs to be digested by microbes first.

Both can lead to healthy plants, but the process is fundamentally different. And as you’ll soon see, your aquarium is already a master at creating the perfect organic “meal” for plants.

So, Is General Hydroponics Organic? The Straight Answer

Let’s get right to it. The flagship product line from General Hydroponics, the Flora Series (FloraGro, FloraBloom, and FloraMicro), is not certified organic.

These are high-quality, effective nutrients, but they are made from refined mineral salts. This allows for incredible precision and control over plant nutrition, which is why they are so popular in commercial and hobby hydroponics. However, their synthetic nature disqualifies them from organic certification.

One of the common problems with is general hydroponics organic inquiries is this very confusion. People see lush, healthy plants and assume the method is “natural,” but it doesn’t align with the agricultural definition of organic.

It’s important to note that General Hydroponics does have an OMRI-listed line called the BioThrive series. These products are formulated to meet organic standards. However, for an aquarist, buying bottled nutrients—even organic ones—is missing the incredible opportunity sitting right in your living room.

The Aquarist’s Alternative: True, Eco-Friendly Organic Hydroponics with Aquaponics

Okay, so the most popular hydroponic nutrients aren’t organic. Don’t worry! As a fishkeeper, you are already halfway to running a system that is not only organic but also beautifully self-sustaining. Welcome to the world of aquaponics.

Aquaponics is the marriage of aquaculture (raising fish) and hydroponics (growing plants in water). It’s a perfect, closed-loop system where fish and plants help each other thrive.

Remember the nitrogen cycle you worked so hard to establish in your tank?

  1. Your fish produce waste, which is primarily ammonia.
  2. Beneficial bacteria convert that toxic ammonia into nitrites.
  3. A second type of beneficial bacteria converts the nitrites into nitrates.

In a normal aquarium, nitrates build up, and you remove them with water changes. But in an aquaponics system, those nitrates are pure gold. They are the perfect, naturally produced fertilizer for plants! By pumping that water over plant roots, you create a truly sustainable is general hydroponics organic system right in your home.

Your “Is General Hydroponics Organic Guide” to Starting a Simple Aquaponics System

Ready to give it a try? You don’t need a massive, commercial setup. You can start small with a 10 or 20-gallon tank. Here’s a simple is general hydroponics organic guide to get you started.

Step 1: Choosing Your Fish and Plants

For your first system, choose hardy species. Don’t worry—these fish are perfect for beginners!

  • Fish: Goldfish, guppies, mollies, or even a betta can work in a small system. They are robust and produce enough waste to feed a few plants.
  • Plants: Start with leafy greens and herbs that don’t need intense nutrients. Lettuce, basil, mint, parsley, and even house plants like Pothos or Peace Lilies are fantastic choices.

Step 2: Setting Up the System (Media Bed Method)

The easiest method for a beginner is the media-filled bed. You’ll place a container (a simple plastic tub works) above your aquarium to serve as the “grow bed.”

  1. Drill small holes in the bottom of the tub for drainage.
  2. Fill the tub with an inert growing medium like clay pebbles (LECA) or lava rock. This provides support for the plant roots and a massive surface area for beneficial bacteria to live.
  3. Place your plants directly into the media.

Step 3: Connecting the Water Flow

You need a small, submersible water pump in your aquarium. Attach a vinyl tube that runs from the pump up to your grow bed, letting the aquarium water trickle through the media. Gravity will then do the work, allowing the now-filtered water to drain back into your tank through the holes you drilled.

Step 4: Cycling Your New System

Just like an aquarium, your aquaponics system needs to “cycle.” The bacteria in your tank’s filter are a great start, but the colony will need to expand into your new grow bed media. Monitor your ammonia, nitrite, and nitrate levels. You’ll see nitrates drop as your plants start to grow and consume them. This is the magic of aquaponics in action!

Best Practices for a Thriving Organic Aquaponics Tank

Maintaining your new ecosystem is easy once you get the hang of it. This is general hydroponics organic care guide focuses on balance, observation, and letting nature do the work.

Monitoring Water Parameters

Keep testing your water, but pay special attention to two things: pH and nitrates. The ideal pH for an aquaponics system is between 6.0 and 7.0, which is a happy medium for fish, plants, and bacteria. Your nitrates should stay relatively low (under 40 ppm) because your plants are using them as food! If they are at zero, you might need more fish or to feed a bit more.

Feeding Your Fish for Plant Success

In aquaponics, your fish food is your fertilizer. A high-quality fish food is the single most important input. What you feed your fish directly determines the nutrient profile available to your plants. Choose a food with a good balance of protein and essential nutrients.

Managing Common Problems: Nutrient Deficiencies and Pests

One of the most common issues is an iron deficiency, which shows up as yellowing leaves with green veins. You can supplement this with an aquaponics-safe chelated iron. Because you can’t use chemical pesticides, introduce beneficial insects like ladybugs or use natural sprays like neem oil if pests appear.

The Amazing Benefits of This Organic Approach

So, why go through the trouble? The benefits of is general hydroponics organic-style aquaponics are incredible, especially for an aquarist.

  • Dramatically Fewer Water Changes: Your plants act as a powerful, natural filter, removing nitrates for you. You’ll mostly just need to top off the water lost to evaporation.
  • Fresh, Organic Produce: Imagine snipping fresh basil for your pasta or grabbing lettuce for a salad, grown right above your aquarium. It doesn’t get more local or organic than that!
  • A Living Science Lesson: An aquaponics system is a fantastic educational tool that beautifully demonstrates natural cycles. It’s a complete ecosystem in miniature.
  • Truly Sustainable and Eco-Friendly: You’re using less water than traditional gardening, eliminating fertilizer runoff, and creating food from what was once considered “waste.”

Frequently Asked Questions About General Hydroponics, Organic Growing, and Aquaponics

Can I use General Hydroponics nutrients in my aquaponics system?

Absolutely not. The mineral salts in synthetic nutrients like the General Hydroponics Flora Series are toxic to fish and would destroy the delicate biological balance of your system. Stick to fish food as your only fertilizer input.

What are the best fish for a small home aquaponics setup?

For beginners, hardy fish are best. Guppies, platies, and mollies are great because they are active and reproduce easily. Goldfish are also excellent waste producers. For a desktop nano system, a single Betta can happily support a small herb or two.

Is aquaponics hard to start?

Not at all! If you can maintain a healthy aquarium, you already have 90% of the skills you need. You understand the nitrogen cycle, water testing, and animal care. The rest is just simple plumbing. You can start with a kit or a simple DIY setup like the one described above.

Do I still need to do water changes in an aquaponics system?

You’ll do them far less frequently. While plants remove nitrates, other minerals and solids can build up over time. A small, 10-15% water change once a month is often enough to keep everything in balance, compared to weekly changes in a standard tank.

Your Journey to a Living Ecosystem Awaits

So, while the direct answer to “is general hydroponics organic” is generally no for their most famous products, the question opens a door to something far more exciting for an aquarium enthusiast.

You have the power to create a truly living, cyclical ecosystem that is not only sustainable and eco-friendly but also incredibly rewarding. You can transform your aquarium from a beautiful display into a productive powerhouse that filters its own water and provides you with fresh, organic food.

Start small, choose easy plants, and enjoy the process of watching your two hobbies merge into one. Happy fishkeeping and happy growing!
