Rated 4.4 out of 5 by 45 reviewers.
Rated 5.0 out of 5.0 by Great product! Great deal! I use this product to add to my potting soil and to root some of my Hoya cuttings. The some of my Hoya cuttings rooted less then 2 weeks. I use this product for semi hydro planting on my orchids too. Great product! Great deal! September 3, 2013
Rated 4.0 out of 5.0 by As Expected This stuff was what it should be & for a reasonable price. I used 200 Lbs which filled one Aquaponics bed. I have two others to do and will use this again. Compared to other product prices this was the best I could find for the amount ordered & it was delivered quickly by UPS & no shipping charge. It does need to be rinsed before using but that was easy after developing a decent method. May 27, 2014
Rated 5.0 out of 5.0 by Good product, readily available. Purchased this to use as media in a flood-and-drain aquaponics system. Works very well for this purpose. Things to note are: - Media must be rinsed thoroughly before use, to remove the clay dust. Failure to do this could cause clouding (of concern in an aquaponics system, maybe not so much for hydroponics) and the powdered clay forming a sludge that could be detrimental to the pumps and plumbing. - Expanded clay has some air in it, and will not sink like a stone. It does have a tendency to rise, especially when bone-dry, or if the media is drowned and submerged to its complete depth. In our system, for a grow bed depth of 16 inches, we had to set the overflow drain 3 inches BELOW the top level of the media, and that allowed the weight of the unsubmerged media to counter the floating of the submered media and keep the whole system in place. In summary, the quality, availability and pricing (especially with the ship-to-store option that helps offset the steep shipping for this large heavy item) makes this product and HomeDepot a winning combination.

Rated 5.0 out of 5.0 by The right stuff at the right price The right stuff at the right price works great in your aquaponics system. March 27, 2013
Rated 5.0 out of 5.0 by Great deal Bought 5 bags, great price, free shipping. Must be rinsed before using for hydro/aquaponics. They do float but an extra inch or two on top will keep em down. Only wish that they carried it in stores...hope it's in stock when you need it ;) May 8, 2015
Rated 5.0 out of 5.0 by Great product Am using this product in my aquaponic garden and like it a lot. It is a bit dirty so had to rinse it off before I added it to my system but other than that I love it. May 6, 2015
Rated 5.0 out of 5.0 by Very Good growing media I have purchased 6 bags so far and am very pleased..This product is being used in my Aqua pontics systems. The plants and fish both seem to thrive very well. 50 LT. is about 12.25 gallons and weighs around 29 LBS. March 19, 2013
Rated 5.0 out of 5.0 by Fast delivery, clean and ready to use Best price and as described. This is the first time I've used this product and it appears to be better than using rock wool or coco fiber. March 19, 2013
