3 Gallon Bag Garden Pumice (3/16" + 5/16" Blend) 12lbs

I only order General Pumice, it is the best price for the best quality. Unlike some others this is not extremely soft, doesn’t require extra screening, isn’t half dust at the bottom of the bag like others. I mix 50% 3/8” pumice to soil for succulents. Size is consistent. You won’t regret it if you get it.

I am happy I purchased this for my seed starting mix. I will say, it was shipped USPS so shipping was very slow, if you live in an area where USPS takes forever to deliver, keep that in mind. My seed starting was delayed over 5 days because of USPS having issues with redelivering. The product itself is great, I just know to order in advance next time to avoid losing anytime for my seed starting!

I have been wanting to create a gritty mix that includes pumice for my succulents for when they go outside for the summer. I live in Missouri, so it rains a lot sometimes and the succulents suffer a bit. This stuff is excellent. Perfect size, exactly what's advertised. Since it's pumice, it doesn't ever have to be thrown out, either -- you can reuse it for other plants for as long as you need to. That aside, I wish I had thought about the impact it would have to inhale the dust off of the pumice! UGH! Be careful -- you're essentially inhaling tiny particles of silica glass into your lungs and it is really unpleasant. I coughed a lot and had serious congestion issues for a few days after that stupidity.

The size of these stones are a great replacement for perlite and also a great size to mix in for a DIY pon mix. Will definitely buy more!

This pumice from General Pumice Products is excellent for my purpose (potting mix). The size is uniform and accurately described by the seller, and although a tiny portion of the particles are some other mineral (quartz, I think), this is common with pumice and doesn't hurt the plants.It could have been cleaner. I washed it and strained it. I didn't mind doing this but you might.If that was the whole story I'd give this product five stars, but the seller shipped less than promised. At the time I bought this, the description was, "3 Gallon Bag Garden Pumice (1/8" Stone) - 12lbs."I received 2. 6 gallons not 3 gallons. The seller is probably doing this with all their US customers because they shipped the product in a USPS flat rate box that only holds 2.36 gallons. They managed to squeeze in a little more than 2.36 gallons by bulging out the cardboard sides of the box, but they would have had to turn the box into a balloon to cram the promised 3 gallons into it.Usually if a seller ships less than they promise, I give them 1 star because I think it's fraud and and it's unacceptable. But in this case I think the seller might just be confused. Inside the shipping box, the material was packaged in a heat-sealed bag labeled "3 gallons", and it's quite possible the seller buys this stuff in the bags from somebody else and assumes it's really 3 gallons and never measured it.Also, the seller promised 12 pounds but sent 12.9 pounds. In other words, I got less by volume but more by weight than they promised.You might think weight vs volume sort of balance out so there's no real problem. But the weight of pumice doesn't tell you very much about the amount of pumice because pumice absorbs water so easily -- pumice is a sponge made out of rock -- and the weight goes up and down with the water content. In contrast, volume remains the same regardless of water content. So volume (gallons) is much more meaningful than weight. The pumice wasn't obviously wet when it arrived but it was grayer (less white) than this particular pumice gets when it dries completely.Like I said, if the seller had described this accurately (2.6 gallons of pumice) I would have given it 5 stars.

I havnt even received my order yet but these are the only people I will buy from since about 5x's ago when I ordered from them! The 1st time ordering there was a big misunderstanding and unfortunately I was having a VERY BAD DAY and kinda snapped on them, but the lady was just as sweet as could be and was SO NICE 2 me to where I had no choice but to start having a better day!!! Then, when I received the pumice, it was/is the BEST pumice I've personally come across! (And I've come across A lot from many different places) Very clean, very uniform & the sizes you order are actually the real sizes u will order!!! Even the littelist size was perfect for me to do my seedlings in!. I don't know of anyone else on Amazon that will make pumice this small. This time I needed the 3/8th which is my "regular" size and it's perfect for my cacti! As with ANY pumice tho, be sure to rinse it off 1st, as it's always gonna be dusty but that's gonna be for every place you get it from tho). Now, if these folks would just start selling some decent green zeolite, my cacti would be in heaven!!! I wish I could do a pic for all yall but I haven't even received this order yet and I'm COMPLEATLY OUT, ur just gonna have to trust me. :-D I don't just give Anyone 5 stars!!! :-) Thank you, General Pumice, I appreciate y'all!!!

Great no problems, prompt delivery.

Very nice to order a bag of pumice without getting half a bag of dust. Will definitely order again.
