Grow Medium 100% VCF Grow Nutrients


Your grow medium is one of the most important parts of your grow. Without good soil, coco or hydroponics your plants will not produce as you wish them to. If you are growing indoors the medium that you use will determine to a great extent whether you have a good or not so good grow and harvest.

For a good indoor grow you will need either Coco Coir, Earth or Hydroponics. Many growers grow only in Coco mixed with Perlite which is a natural product made from vulcanic stone.




Coco Coir is nothing more than shredded coconut shell, but make a great grow medium. When using coco it is wise to make sure that you give your plant enough calcium and magnesium because it contains 0% nutrients that your plant could benefit from. Coco is also considered hydroponic. Coconut coir can be used as the growing medium for both seedlings and mature plants. No matter what form of coco coir you're using, always soak it thoroughly in water before you plant, and pay careful attention to the moisture level during the growing blooming periods.

The best use of coco coir for potted plants is to mix it with potting soil. You can use coco by itself if you supply your plant with enough nutrients such as calcium and magnesium. But in general you want to mix it with potting soil. The reason for that is it has no nutrients in it, and if you're using this grow medium outside of a hydroponic system, you'll want to combine it with something that does contain nutrients.




Potting soil is the best soil for containers as it gives the right texture and moisture retention for growing plants in a small space. It also will not compact like topsoil or plain garden soil in container, which allows for better root growth of container plants. When using earth it is usually mixed with some type material to help get more air to the soil. Earth, if it is not organic is usually loaded with chemicals that you have to flush out later, unless you are using bio or some type of organic soil.




Put simply: Hydroponics is a way to skip the soil, and use a different material to support the roots of the plant, and grow crops directly in nutrient rich water. There are multiple approaches to designing hydroponic systems, but the core elements are essentially the same.

Plants grown hydroponically grow significantly faster than soil-grown plants. This is because the plant's roots are literally bathing in nutrients, so they can easily and directly absorb them with minimal effort.

5 Disadvantages of Hydroponics
  • Expensive to set up. Compared to a traditional garden, a hydroponics system is more expensive to acquire and build.
  • Vulnerable to power outages.
  • Requires constant monitoring and maintenance.
  • Waterborne diseases.
  • Problems affect plants quicker.
There is a stigma about hydroponic crops having little flavor or are “watered down”, but this is no longer the case. The proof is in the eating, and plants that are fed a balanced diet will grow bigger and produce better tasting crops.



Perlite is one of nature's best media for growing plants. It is possible to grow most plants in perlite alone, but usually the finer grades and medium grades will work better and require less water. Seeds can be started in any grade of perlite, but with smaller seeds, finer grades of perlite would be recommended.

Too much perlite in potting soil will cause water to drain out too quickly. A possible sign of too much perlite is when the plant starts the schrivel or yellow and the soil remains dry even though you water regularly.

Even though vermiculite and perlite are safe for vegetables, that doesn't mean they are necessary for them. All plants need good drainage, but certain vegetables will do better with really loose and aerated soil. Not only are they safe, they can be extremely helpful in keeping your plants healthy and productive.
