What is perlite made out of?
Perlite is a lightweight granular material that’s white in colour. It looks and feels like little bits of polystyrene but is actually made from expanded volcanic glass, heated to 1000°C until it ‘pops’ (like popcorn) to many times its original size. It’s lightweight, sterile, and easy to handle, and is long-lasting.

What is vermiculite for plants?

Can I use charcoal instead of perlite?
Charcoal is often used as a substitute for perlite as it possesses the same functional qualities. Charcoal speeds drainage, inhibits bacteria and fungal development and allows good air flow and is therefore a good option for inclusion in potting medium for a range of plants.
Can I use sand instead of perlite?
The fine particles will make the soil mix like concrete. You are better off not using sand at all if you can not get the right sand. Perlite is a good alternative to sand but it has drawbacks. In some areas it is hard to find perlite that is not salty.

Can I use bean bag beans instead of perlite?

Can I use polystyrene for plants?
Break it up into large pieces and use as the base layer to the oversized containers before filling the rest of the space up with compost. They are lighter than soil and still allow water drainage.
Is perlite man made?
Perlite is an amorphous volcanic glass that has a relatively high water content, typically formed by the hydration of obsidian. It occurs naturally and has the unusual property of greatly expanding when heated sufficiently.
How is vermiculite made?
It is derived from rocks containing large crystals of the minerals biotite and iron-bearing phlogopite. As these rocks are exposed to the weather, they start to decompose, allowing water to enter and react with the various chemicals present. As the decomposition and chemical reactions proceed, vermiculite is formed.
Where is perlite found?
Perlite is a volcanic rock mined in the United States, as well as other countries like China, Greece, and Italy. The volcanic glass, or perlite, is formed when lava (molten rock) spews out of a volcano, and cools in a rapid manner.
Do I need perlite in potting mix?

Is perlite good for tomatoes?
Perlite is one of the best ways to enhance the quality of potting soil and multi-purpose compost – tomato plants love it! It is a volcanic rock material that when heated to around 900 degrees C, expands to thirteen times its own volume.

What are the disadvantages of perlite?
Cons: Water can drain away quickly. Being so lightweight, perlite can be blown away and tends to float in excess water. Nonrenewable resource. Dust can create respiratory problems and eye irritation.
Which plants like vermiculite?
Vermiculite is perfect for plants that enjoy lots of water, such as some irises and forget-me-nots. Perlite dries out too quickly for water-loving plants. The amount of water that vermiculite holds is too much for plants like cacti, succulents, or rhododendrons, which need a well-draining soil.
