Remember growing one of these as a child? Although you didn't know it at the time... this was your first attempt at hydroponics!
What exactly is hydroponics? By definition:
"The cultivation of plants by placing the roots in liquid nutrient solutions rather than in soil".
Now, I know that you've arrived at our website wanting to grow more than just a potato vine on your windowsill... and we'll get you where you want to go... simply and easily. But with a solid knowledge base to guide you.
Learn now about the hydroponic growing medium required for your new garden...
The hallmark of hydroponic gardening is a soil-less growing medium... No soil! But plants need to be supported or held up somehow, right? We do this with soil-less media... inert, non-organic materials.
They do not add to or change the chemical
makeup of the nutrient solution in any way. These substances are porous, light,
and coarse, which allows oxygen and nutrients easy access to the plants roots.
If you open up any hydroponics catalogue, you'll quickly become confused by the array of hydroponic growing medium choices available today.
Yikes! Which one will be best for my garden?
Glad you asked that... we're going to make this simple and painless...
There are only 3 basic growing media that we recommend for your first gardens:
That's it. Forget about gravel or HigroMite or
vermiculite or rockwool. Later, if you want to branch out and learn about other
growing media, visit our "Advanced Hydro" section (coming soon).
There are also two advanced hydroponic techniques that don't use any hydroponic growing medium whatsoever... aeroponics and NFT (nutrient film technique). Later...
For now, all you need to know about are the "Big 3": Coco, LECA, and perlite. Each has advantages and disadvantages, and so are better suited to specific growing systems.
Coco Coir and perlite are denser, and hold
water better, but LECA has superior drainage and aeration. Experienced
hydroponics nuts usually have their own favorite formulas using these 3 media.
