Perlite is a unique volcanic mineral which expands from four to twenty times its original volume when it is quickly heated to a temperature of approximately 1600-1700 degrees F. This expansion is due to the presence of two to six percent combined water in the crude perlite rock which causes the perlite to pop in a manner similar to that of popcorn. When expanded, each granular, snow-white particle of perlite is sterile with a neutral pH and contains many tiny, closed cells or bubbles. The surface of each particle is covered with tiny cavities which provide an extremely large surface area. These surfaces hold moisture and nutrients and make them available to plant roots. In addition, because of the physical shape of each particle, air passages are formed which provide optimum aeration and drainage. Because perlite is sterile, it is free of disease, seeds, and insects. 3.53 Cubic Feet. This product weighs 22.4-pound. Measures 36-inch length by 20-inch width by 12-inch height.

The last medium that I was using was a mixture of medium size bark and gravel which worked great until !!!! The bark broke down, rotted, developed white fungus and mildew. Then my orchids started dying from too much water and different type of diseases that followed. To make matters worse, the ants started living inside the pots and the slugs decided that them roots are pretty darn good stuff! Aaaarg!
Anywho ... after reading the internet articles on the use of perlite, I went down to my local nursery and got a large bag of the stuff and proceeded to take ALL of my plants and replaced the medium with gravel, perlite and small black lave rocks. It's been three months and they are all doing very well flowering and bringing up new shoots.
For those interested here's how I replanted my orchids: One 8" Azealia (sp) pot, Cover the holes with a piece of broken clay pot and or rocks. Fill 1" of 1/4"-1/2" gravel for weight and drainage, fill the rest of the pot (up to 1" from the top) with coarse perlite, and the rest with black lava rock.
I you don't have black lava rock you can use pea gravel for the topping. The reason for this is because a) perlite is light and a strong wind will blow the perlite (and the plant) from the pot and b) white perlite turns green after a while and small or black gray rocks looks much better.
Water once a week or more if needed and the beauty of using this medium is that it's almost impossible to over water which is what kills most plants and orchids! TIP: Get a 20 gal or 42 gal (whatever) garbage can. Wear a painter's mask, fill 1/2 of the garbage can with water and dump the perlite into the water. PUSH the perlite down into the water and swish it around a few times to make the fine particles go down to the bottom. YOU DON'T WANT TO BREATH THIS STUFF!. You can use the water to water your plants until there' only about 2" of water left at the bottom.
You can then dump the remaining water into your lawn or whatever. The fine particles will not harm anything and may even help in loosening the soil. Hope this helps someone.
The only real issue I have with it is that Algae grows this at about 4 times the rate of clay pebbles. So while I am a big fan of this for my plants root structure, it does have some hurdles to overcome.
It is a good product and worked well for my hydroponics but not for $60!!!! I will go elsewhere. ☹️
Though it's not for what I originally needed it for, it's cheap enough to use in my soil mixes. I was looking for larger pieces for hydroponics.
One star dropped off due to it not being what I expected. I have seen much larger perlite in my local store.
