Vermiculite is an incredible substance that not only helps provide essential moisture to your plants it also helps negate root rot.
Capable of replacing soil in hydroponics and is often used to germinate seeds, vermiculite is a growing media that can be mixed with soil or in place of soil depending on your specific needs and requirements.
Vermiculite also comes in many different sizes and gradients and each particular size and gradient has its own set of benefits and its own set of uses.
It is important therefore to fully research vermiculite and its various types so you can pick the perfect vermiculite for you and your growing environment.
Many growers find that once they have tried vermiculite they just cannot do without it and it’s easy to see why.
Vermiculite has a fantastic ability to take in and retain water and this helps germination as the water retention means that seeds can therefore absorb and grow steadily, slowly, and efficiently.
Additionally, vermiculite prevents compaction of the soil which in turn means that the environment is better aerated and plants are neither suffocated from lack of oxygen or from too much weight.
If you decide to completely replace soil with vermiculite this can have further beneficial effects as vermiculite contains many nutrients that are difficult to find in most soils, such as calcium and ammonium which can accelerate growth.
Alternatively, if you wish to mix vermiculite with your favorite soil, this can help prevent one of the main fears for all growers; root rot.
In addition to this, whilst preventing rotting roots, due to vermiculites’ water retention abilities, it also simultaneously stops the plant from drying out.
Vermiculite is a must for the serious grower who wants to improve their growing environment with minimal fuss.

Vermiculite Buyers Guide
One of the most impressive things about vermiculite is that when it is mixed with your soil it will interact and optimize the potassium, calcium, and magnesium contained within, and even though vermiculite is pH neutral, it can in some cases actually beneficially raise the pH level in your soil.
Vermiculite is created from dry flakes of silicate which is both spongy and absorbent.
Most standard vermiculite is a golden brown but other varieties can be darker and can therefore sometimes be indistinguishable from potting soil.
Vermiculite really comes into its own though when water is added to it and it expands into worm-like shapes, that almost act like sponges.
If you require your soil to not dry out and stay consult damp but not waterlogged, then vermiculite sounds perfect for your situation.
Vermiculite is capable of expanding up to 4 times its size when water is added, so fair warning, this can make plant pots that contain it slightly heavy.
In contrast to perlite, as vermiculite is able to absorb far more water, vermiculite although capable of providing some aeration is obviously heavier, (especially when wet), and doesn’t aerate the soil as well as perlite does.
It is important therefore to understand your plants’ specific needs before using vermiculite as plants that don’t need consistently damp soil, may suffer from a lack of oxygen and actually end up suffering from root rot.
Providing you are aware of what your plants and your growing environment need in terms of water retention and aeration, vermiculite if used correctly can be an invaluable tool.
Where plants do need to maintain a constant hydration and nutrient level, vermiculite will be invaluable, because as many experienced growers will tell you; water-loving plants love nothing more than vermiculite.
