This is perfect leca. Nice and tiny size makes it so pleasant to plant with. Requires the usual rinsing and a bit of sifting to remove broken bits, but less than some other brands I tried. Bag seems small, but will fill at least two 6” pots and then some. Would be buying again. If you’re new to leca: wash it like rice, rinsing until the water is mostly clear behind first use. Wash out outside, don’t let clay down your drain. I also recommend using a sifter after the first rinse to separate the fines. Pro tip: store the clean leca in nutrient water, so it’s hydrated and ready to go when planting. I store mine in a giant cleaned out costco pretzels container, but a 4qt cambro should also work. Remember leca is super lightweight but voluminous,

Good leca compared to most. About half of them sank after soaking for 48 hours. I boiled the remaining half that was still floating to release the air pockets for about 10 minutes. Then let them sit in the water for another 5 minutes and they all sank.

So pleased with the Organic Expanded Clay ( Balls ) pebbles. Great quality, they are in different sizes too. Rinsed w/ water in a bucket, to remove all the clay dust. I had orchid knats and it was very annoying and damaging my orchids. I had sprayed weekly with Neem Oil on the orchid wood chips, to kill the knats with no success! I had watched several youtube videos about re planting orchids and the clay pebbles. I also had ordered 5" clear plastic orchid cups with holes on the sides and bottom, great quality too! I have noticed new very small growth on the orchids. So pleased with the Clay Pebbles & the Success!

Great for creating extra drainage at the bottom of a pot or mixing in with other mediums. I also like to use them to mulch some of my house plants or young cuts that I am trying to root. Be warned, they are very DIRTY and create a big red cloud of dust when poured into a pot. Also, these are very buoyant and will float, which you may want to consider if using them as a primary medium or for hydroponic gardens.

Shapes and sizes inconsistent. Most of pebbles are 1/4 the size of the larger ones. Not “4lbs”. Advertisements are just a bit misleading. They arent packaged in the same bags shown in the pictures. Just a plain grey bag. I only bought these because I can get them nowhere else. The bag of pebbles is about equivalent to a shoe box storage container. Almost fills the tote which is about 6in W x 12in L x 4in H. None of this is particularly bad, they will still serve their purpose, but I just wish the description and pictures were more accurate.
