This video shows and explaines the diffrence between using a air stone versus the AIT Air Injection Technology for use in a water reservoir to grow hydroponics. The right amount of air to your plants roots is the single most important thing when growing with hydroponics. AIT or Air Injection Technology provides an even amount of air through out your water reservoir. Use AIT with Deep Water Culture (DWC) or with Ebb and Flood type systems. Produces white, clean, crisp roots.

What is Aquaponics?

Are you wondering “what is aquaponics?” The most simple definition is that it is the marriage of aquaculture (raising fish) and hydroponics (the soil-less growing of plants) that grows fish and plants together in one integrated system. The fish waste provides an organic food source for the growing plants and the plants provide a natural filter for the water the fish live in. The third participants are the microbes (nitrifying bacteria) and composting red worms that thrive in the growing media. They do the job of converting the ammonia from the fish waste first into nitrites, then into nitrates and the solids into vermicompost that that are food for the plants.
In combining both systems aquaponics capitalizes on the benefits and eliminates the drawbacks of each.
How aquaponics changes the game
 Waist-high aquaponics gardening eliminates weeds, back strain and small animal access to your garden.
 Reuse resources currently considered “waste”. In aquaponics there is no more toxic run-off from either hydroponics or aquaculture.
 Aquaponics uses only 1/10th of the water of soil-based gardening, and even less water than hydroponics or recirculating aquaculture.
 Watering is integral to an aquaponics system. You can’t under-water or over-water.
 Fertilizing is also integral to an aquaponics system. You can’t over-fertilize or under-fertilize.
 Gardening chores are cut down dramatically or eliminated. The aquaponics grower is able to focus on the enjoyable tasks of feeding the fish and tending and harvesting the plants.
Instead of using dirt or toxic chemical solutions to grow plants, aquaponics uses highly nutritious fish effluent that contains all the required nutrients for optimum plant growth. Instead of discharging water, aquaponics uses the plants and the media in which they grow to clean and purify the water, after which it is returned to the fish tank. This water can be reused indefinitely and will only need to be replaced when it is lost through transpiration and evaporation. Two primary methods of aquaponics growing are most widely in use today.
 The raft based aquaponics growing system uses a foam raft that is floating in a channel filled with fish effluent water that has been through filtration to remove solid wastes. Plants are placed in holes in the raft and the roots dangle freely in the water. This method is most appropriate for growing salad greens and other fast growing, relatively low-nutrient plants.
 The second method is called media based aquaponics because plants are grown in inert planting media (gravel, expanded clay pellets, coir, etc.). The media provides both the biological (ammonia based waste) and mechanical (solid waste) filtration, so requires far less maintenance than raft-based systems. Large, fruiting plants are also grown much more successfully in media based systems than in rafts.
 The third method is called hybrid aquaponics, which is a combination of the two. The media beds become the pre-filter for the solid waste before the water enters the raft systems. This hybrid system style is the focus of The Aquaponic Source’s AquaBundance systems because it provides planting flexibility, high productivity and low maintenance.

    This is bullshit the tub on the left had more water in so of course it'll soak the paper towel first the water has less to jump. And I'm sure the pump on the right was turned down

    Your paper towel experiment lost its credibility the moment you edited the video at 2:18 . For all we know, you unplugged the pump for the container on the right and plugged it back in later before you resumed filming. Im not saying you did, Im just saying your experiment lost its Youtube credibility the moment you decided to edit the video.

    I did a static hydro grow (meaning no Air Stone or pump) it was Basil DWC
    At 1st I thought it would not even work, I got an amazing amount of basil all year long.
    Changed the water once a week, and in the end of the season the plants were done. I did found it had great roots no real algae or mold problem. I think a little hydrogen peroxide would of fixed that if I needed it, but I never did. Just letting you know, Hydroponics doesn't have to be complicated or expensive to have a great crop.

    @Don007206 Actually, the idea behind the Air Injection Technology is to defuse the air into the water more evenly and focuses more on maximum bubble count rather than larger bubbles. You may not be able to see it in the video but AIT has many times more bubbles diffused in the water (The air stone has much larger bubbles)

    Its kinda hard to show in a video so we tried to come up with a creative way to illustrate this through the paper towel test. I'm sorry you do not approve.

    This is crap there is not more air just bigger bubs so air escapes water faster I would rather have a million little buns that way the water is air rich for roots

  • ModularHydro

    @NecroplantTheNoob Indeed. Our advantage comes from the increased distribution of bubbles. When you increase the number of individual bubbles begin created, you also increase the surface area of the air that's actually in contact with the water.

    So this is basically an air pump without an airstone. I'm about to start 3 or 4 deep-water systems for beefsteak tomato seedlings. I've read that aquarium air stones are not really required for fish aquariums unless there is a septic nightmare that is restricting the flow of oxygen. So I came to this video because I've been curious how it would be without an airstone. It makes sense: it's just supplying oxygen either way.

    @HowToHydroponics It sure is. All our Direct Top Feed (DTF) & Deep Water Culture (DWC) systems have Air Injection Technology Included. You can view these systems at shop(dot)modularhydro(dot)com. Thank you for the question 🙂
