The best part about hydroponic organic gardening is you don’t need soil to grow an organic garden. However, this concept can be confusing. As discussed previously, part of what makes organic gardening; organic gardening, is using organic soil. If you don’t have organic soil, how could it be an organic garden? This section will show you why hydroponic organic gardening can be advantageous over regular organic gardens.
The key to organic hydroponic gardening is the water. The organic plants get their nutrients from the water, not soil. Organic plants, even hydroponic ones, can’t grow until they have a solid substance to put their roots into. You can grow organic plants hydroponically by putting them in vermiculite and perilite. A word of caution is in order: When handling vermiculite, the utmost care must be taken. This is because vermiculite is a form of asbestos. You can also use organic materials such as straw, cotton, plant fiber, or any number of other organic materials.
Preparing the water for your hydroponic organic garden
Since the water is the sole source of your organic plants nutrition and not soil; your organic plants must have nutrient rich water to feed their roots. Since the goal is to grow an organic garden, all nutrients dissolved, in the water, must be organic. One such nutrient commonly used in organic hydroponic gardens is what is referred to as “compost tea.” Compost tea is created when compost is put into water. The water is infused with the organic compost material. Once the organic compost has been fully saturated by the water, the water is then strained. It is necessary to strain the water because any solid compost material remaining must be removed. What’s left, after the water has been strained, is an organic, nutrient rich, water; which your organic plants will love to drink.
You can also make what is commonly referred to as manure tea. However, it can be dangerous to make your own manure tea. There is a risk of getting bacterial contamination on your organic hydroponic garden vegetables. You could actually contaminate your vegetables with lethal strains of E. coli. The manure used for manure tea should be thoroughly broken down through decomposition. You can also create manure tea with sterilized manure. The process to make manure tea is the same as you would use to make compost tea. Other common organic materials, which can be combined with the water, include seaweed and fish emulsion. The benefits of using seaweed were discussed in depth in the organic fertilizer section.
The other advantage to hydroponically growing your organic garden is you won’t waste water. The nutrient rich water can be continuously used on your plants. In other words, unlike a traditional organic garden, the water used is not wasted. The nutrient rich water, used to feed your hydroponic organic garden, isn’t used one time and then thrown away. You should keep recycling the nutrient rich water to feed your plants; over and over again.
As you can see, an organic hydroponic garden can be a more practical, viable, solution compared to growing a regular, organic garden. It is true; you won’t get the same “earthy” experience a regular organic garden would provide. After all, there is no “earth” to dig in. However, you will still get the same delicious, chemical free, home grown, organic vegetables.
Hopefully, this guide has convinced you to garden organically. As discussed, not only is it beneficial to your health; and the health of your loved ones, it will also be beneficial to the environment. Organic gardening does not really require much more additional effort than it takes to grow a non-organic garden. However, the benefits you get in return, for going organic, are numerous.
