7.2.2.1 Perlite. Production, Origin, and General Information—Perlite is a glassy volcanic rock with a rhyolitic composition and 2%–5% of combined water (Alkan and Dŏgan, 1998; Dŏgan and Alkan, 2004; Kaufhold et al., 2014 ). The major known global perlite resources (about 70%) are located along the Aegean coast in Turkey.

Vermiculite can soak up 3 to 4 times its volume in water. It also attracts plant nutrients such as potassium, magnesium, calcium and phosphorus. Perlite is an amorphous volcanic rock that is rich in silicon. When mined for use as a potting medium, perlite is crushed and also heated to expand the particles.

After 4 weeks. Vermiculite: The top 1/8 inch (3.175 mm) was very slightly dry. Coconut Coir: The top 2.5 inches was dry. Sphagnum Peat Moss: The top 2.25 inches was dry. As you can see, when it comes to providing aeration (allowing for more oxygen) without a danger to PH balance, perlite blows the competition away.

2. Vermiculite. Vermiculite is a silicate mineral and is ressembles perlite as a growing media that expands in very high temperature. However, it has comparatively higher cation-exchange capacity that enables it to retain nutrients for later use. Vermiculite tends to float because of its very light weight.

Peat moss is the final basic ingredient. This comes in bales or bags and can be sifted to make it less chunky and mix better with the cement and vermiculite. The sphagnum peat moss is mainly what results in the porous nature of hypertufa. The tiny fragments of peat moss will decay over time and create tiny sponge-like breathing holes in the ...

What is perlite? Nicknamed "volcanic popcorn," perlite is made by heating volcanic glass to super high temperatures until it expands and "pops" into the white, porous, lightweight rock that resembles little …

The water trapped in the rock expands, creating a light, porous material. There are various type of perlite, sorted by the average size of the particles, from very fine to quite chunky. Look for coarse or horticultural grade perlite. If it is sold by a numerical grade, look for grades 3 or 4. Vermiculite is made by heating up a type of ...

In the process called exfoliation, vermiculite is heated to between 1,000 and 1,500°F (540 – 810°C). ... The addition of perlite to vermiculite also improves aeration. Vermiculite is an excellent soilless medium for use in hydroponics ...

Pumice is a light-colored, extremely porous rock with a foamy appearance. It is the closest substitute to perlite as it is also formed during explosive volcanic eruptions. Unlike other volcanic rock products for gardening like vermiculite and perlite, it is ready to use in its natural form, and no industrial processing is necessary for its use.

posted 11 years ago. yep that they are however each has a specific insulation value. pumice being the lowest and perlite being the highest. in order to get the insulation values you have to use more materials. so you end up spending just as much to get 4 times the pumice as you would for a two 2 cubic foot of perlite.

Perlite occurs naturally and is a lightweight, volcanic glass or rock. Gardeners use perlite as a soil amendment to improve aeration and drainage while helping to keep the soil from compacting over time. ... Adding perlite and vermiculite will help keep the soil from compacting and create better drainage and aeration for the plant's root system.

Perlite/Vermiculite. Perlite is a substance made from volcanic rock. It is white, light weight and often used as a soil additive to increase aeration and draining of the soil. Vermiculite, which is used the same way as perlite and often mixed together, is made from heat expanded mica and has a flaky, shiny appearance.

Brunnings Perlite, when mixed in the soil, forms spaces to allow water to freely move through the root system and improves aeration and moisture retention.
