Perlite is perlite. It is only differentiated by particle size and brands/suppliers will vary by location. Here it is sold anywhere other gardening supplies are.......Home Depot? Lowe's?

If any outlets are scarce in your area, I'd consider mail order. Perlite is so lightweight, shipping charges would be minimal.

amazon sells it

If you like the larger size perlite (which I tend to prefer), you can purchase it online. Search for "coarse perlite" at Amazon or just Google and you will find many options.

I did and most of the reviews complained about the size misrepresented and lots of it was so tiny to be like "sand or tiny particles". I checked this when I was looking it up and read Amazon reviews mostly....before I even posted this.

Someone of y'all prob have had good experience Lately Thanks all

Perlite almost always need sifting before use. Kind of a perlite fact of life :-)

I buy the large packs from Lowes or Home Depot. It originally looks like a lot but depending on how much gardening you do, you can go through it all in a few weeks or less.

I just did the same with a similarly sized bag of vermiculite a few weeks ago, thinking I maybe had too much for what I needed. Turns out, once you have it, you find ways to make use of it!

I mostly want it to fill up some of the bottom of large containers. They are so heavy filled with pot soil etc. I even I used sticks and leaves to help fill

Like one YOU tuber suggested a Nurseryman," use COARSE perlite" thanks all

Lots of alternatives to fill space in large containers. I use pine cones or pool noodles from the dollar store. To prevent the soil from mixing with them, I put a layer of permeable landscape fabric on top of the filler items before I add my soil.

I buy Miracle Grow Perlite at Walmart

Considering how C-19 is now showing up at multiple Amazon warehouses... you might not want to order from them right now.

Perlite seems an expensive way to fill up empty space. I'm sure there's free stuff around your home which could be used as popmama suggested.

I also use plastic bottles or jugs to fill up large containers. I know some may have reservations about plastic in food containers though, so if you do, only use it for non-food plants.

I've had same large container with flowers for about 5-6 years now. The plastic items are holding up and the plants are thriving in it now that they have really established themselves there.
