Love this leca product, but never expected such a small bag. I expected same as previous order. To expensive for such a small bag.

They’re great! I love using these for my more expensive plants so I can see the root progress. I definitely suggest purchasing.

I really liked this medium, i didn't know what to expect since it was my first time ordering this, but I was able to fill up 6 four inch self watering pots with a 2 pound bag! Absolutely impressed, did wash it before hand!

I am using it for orchids, mainly for the bottom of the pot and use smaller Leca for wicking. My dissatisfaction is with the quality of the class balls. Many are huge, half the size of a golf ball. they are black and look like a piece of charcoal. And it did not come in a CZ bag, just a plain plastic bag with no label. I am very disappointed with this product and in the future will not buy it again.

I ordered two 2lb bags and, even though I did not weigh the product itself, the bags looked smaller than what I expected. In any case, the leca pebbles do its job quite well and work splendidly well with other inorganic substrates such as Seramis.

The quality of the LECA (Lightweight Expanded Clay Aggregate) pebbles was fine. A few were broken, but that's to be expected. Also, I did in fact receive a bit over 2lbs, so I was not technically shorted. However, I was unpleasantly surprised by the volume. For $15.99 I received just over a quart of material (I filled a quart mason jar and had about 20 pebbles left over).Normally I buy this type of material from Josh's Frogs (a Michigan company that specializes in dart frogs and vivarium supplies) but I ordered from Amazon to avoid paying shipping. Josh sells 5 quarts of "false bottom" material (same concept: lightweight material to promote drainage while aiding moisture retention) for $8. So, for the same price I could have gotten ten times as much material (plus shipping). Lesson learned, fool me once...
