Review: The best leca I’ve ever had, the only one I’ll buy - 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,
Review: Pretty good, will actually sink - 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.

## Features

- PREMIUM QUALITY INGREDIENTS: Cz Garden Clay Pebbles are high fired and expanded to create a porous structure that absorbs moisture then releases back to plants when roots need it most.
- GARDENING - Cz Garden Clay Pebbles are all natural and will not leech into your plants, making it ideal for growers of edibles or consumables harvest, such as fruit, vegetables or herbs. Cz Garden Clay Pebbles are guaranteed safe to use in your Organic Garden. NO phosphates, NO Asbestos!
- HYDROPONIC HEAVEN: Cz Garden Clay Pebbles are the #1 Substrate for Hydroponic Gardeners. Why? Because our Clay Pebbles provide outstanding stability for plant roots, ensures excellent root aeration, prevents rotting and excess acidity, does not harvest bugs and discourages fungus gnat growth. Easily fill net pots/cups with our Clay Pebbles in your DWC & NFT Hydroponics, Flood & Drain, Kratky, Aquaponics, Aquaculture, and Tower Garden.
- BEWARE OF FLOATING CLAY PEBBLES: Cz Garden Clay Pebbles SINK. Floating Clay Pebbles do not absorb enough moisture so they “float”. Floating clay pebbles will essentially “float” away when you water your plants. This is especially problematic in hydroponics, aquariums, or if using as a decorative top layer. Cz Garden Clay Pebbles absorb the proper amount of moisture plants desire, so they SINK.
- BEWARE OF WILD pH SWINGS: Cz Garden Clay Pebbles are All Natural, Inert, pH-neutral and stable, clean and decorative. Beware of lower quality clay pebbles with wild ph swings!

### ⭐⭐⭐⭐⭐ Great quality!
*by E***S on 18 May 2020*

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!
