The best place to get volume. Nobody seems to have 4 qf. bags. The price was good on sale too.
I have purchased 8 bags recently and I am very happy with the price and the convenience of having these bulky bags dropped off at my home. The perlite is definitely coarse and perfect for the potting mix I am using for my mango trees. I highly recommend this perlite and will definitely buy from Greenhouse Megastore again.
I love the size of the perlite, it is exactly the size I was looking for and the price point is great as well. Perfect for my potted plants and propagations.
This is a great product. It’s easy to work with-either in the bag or dumped into another container. Convenient size! That’s always a plus!
This is great, I use it for my carnivorous plants, I have ordered the 4 cu. ft. bag several times.
This perlite is a perfect size for mixing with other potting soil for container planting. There's not too much dust.
I was buying this exact same bag from a grow store for twice the price
I used a combination of both perlite and vermiculite in my soil for raised beds and it was great! Super happy with the delivery and service!
Fast shipping. Great quality. Great price
