## Overview

CZ Garden Organic Expanded Clay Pebbles are premium, high-fired porous clay pellets designed to optimize plant root health by providing exceptional aeration and moisture retention. Perfectly pH-neutral and inert, they ensure no chemical interference, making them ideal for hydroponics, aquaponics, orchids, and organic gardening. Packaged in a resealable pouch, these durable pebbles sink (not float), prevent soil compaction, and promote vigorous root growth, delivering a professional-grade growing medium trusted by advanced gardeners and hydroponic enthusiasts alike.

## Description

Clay pebbles are made of 100% natural clay. pH-neutral, clean and at the same time, decorative. Potting media for Orchids - Used alone or in combination with coconut husk chips, bark, charcoal or other orchid media, porous structure can provide excellent aeration around the roots while its ability to act as a water reservoir will be appreciated by your orchids when water is needed. The size of the pebbles is perfect for medium to large Cattleyas and Laelias. Hydroponic/Hydroculture media - The capilliarity and the structure of the clay pebbles ensures good root aeration and prevents rotting, excess acidity and soil pests. Drainage - Compared to gravel, it is lighter and can act as a water reservoir. It can then release the water when its surroundings needed it. Decoration - With its red color and mostly round shape, It is often used as a decorative top-layer for indoor plants and outdoor gardens. As a top layer, it will also prevent the top soil from drying out quickly.

Review: Expanded Clay Pebbles, universally known as LECA (Lightweight Expanded Clay Aggregate), are a staple in advanced growing techniques like hydroponics, aquaponics, and for improving soil. The CZ Garden LECA Grow Media promises versatility for "Plants, Orchids, DWC Hydroponics, Aquaponics, Aquaculture Garden Soil Additive Conditioner Amendment Ceramsite Aggregate." I've rigorously tested this product, focusing on its quality, consistency, and effectiveness across various applications. Upon unboxing, the CZ Garden LECA pebbles immediately convey a sense of professionalism. The pebbles are uniform in size and shape (usually round or irregular spheres), with a consistent reddish-brown color. They feel lightweight, as expected, and have a porous, granular texture. There's usually minimal dust, which is a good sign of quality control. The packaging is robust, ensuring the product arrives intact. Pros: Exceptional Aeration & Drainage: This is LECA's primary strength. Its porous, spherical structure creates abundant air pockets within the root zone, providing unparalleled oxygenation. This is crucial for preventing root rot in hydroponic systems and improving drainage and preventing compaction in soil mixes. Excellent Moisture Retention (Hydroponics): While providing great aeration, LECA also holds a significant amount of water within its porous structure, slowly releasing it to the roots. This makes it ideal for DWC (Deep Water Culture), ebb and flow, and passive hydroponic systems. For orchids, it provides the perfect balance of moisture and air. pH Neutral & Inert: LECA is virtually pH neutral and chemically inert, meaning it won't alter the pH or chemical composition of your nutrient solution or soil. This allows for precise control over nutrient delivery without unwanted interactions from the grow media. Reusable & Durable: LECA pebbles are incredibly durable and can be washed, sterilized (e.g., with hydrogen peroxide or a bleach solution, then rinsed thoroughly), and reused for many growing cycles. This makes them a cost-effective and environmentally friendly option in the long run. Versatile Applications: The CZ Garden LECA lives up to its versatile claims: DWC & Hydroponics: Excellent for net pots, providing support and wicking action. Aquaponics/Aquaculture: Safe for fish and provides a stable medium for plant roots. Orchids: Provides the ideal environment for epiphytic orchids, mimicking their natural growing conditions. Soil Amendment: Improves drainage, aeration, and prevents compaction in heavy soils. Wicking Layer: Great for the bottom of potted plants to create a self-watering reservoir. Prevents Pests & Diseases (in Hydroponics): Being inorganic, LECA doesn't harbor soil-borne pests or diseases, contributing to a cleaner, healthier growing environment in hydroponic setups. Good Consistency in Size: The pebbles are typically uniform in size, ensuring consistent performance and preventing smaller particles from clogging pumps or filters. Cons: Requires Rinsing Before Use: Like most LECA products, a thorough rinsing (sometimes multiple rinses) is necessary before initial use to remove residual clay dust. This is a standard step but can be messy. Lightweight (Can Float Initially): Due to its lightweight nature, LECA can float in hydroponic systems, especially when initially added. This usually resolves as it absorbs water, but it's something to manage during setup. Not a Nutrient Source: Being inert, LECA provides no nutritional value to plants. All nutrients must be supplied via the water or nutrient solution. Cost (Initial): The initial cost per volume can be higher than traditional soil or coco coir, but its reusability often makes it more cost-effective over time. Overall Input & Verdict: CZ Garden Expanded Clay Pebbles (LECA) are an outstanding and indispensable grow media for advanced gardeners and anyone utilizing hydroponics, aquaponics, or seeking to significantly improve their soil's structure. Their exceptional aeration, moisture retention, pH neutrality, and reusability make them a truly versatile and high-performing choice. While requiring an initial rinse and being a bit more expensive upfront, the long-term benefits in terms of plant health, growth rates, and system longevity far outweigh these minor considerations. For optimal root health and superior growing results in specialized applications, CZ Garden LECA is a highly recommended and essential investment.
Review: These clay pebbles are great! I use them for semi hydro for some of my plants. I boiled some of them before use to sterilize them but for the second half of the bag I didn't do that and just soaked them for 24 hours so they would have moisture. My hoyas LOVE life with these pebbles and ever since I've switched them over they're doing amazing. Ofcourse, you have to make sure to fertilize a bit as well as there aren't nutrients in the pebbles. But for certain plants they REALLY thrive in this stuff. Would recommend!

Cz Garden Clay Pebbles absorb the proper amount of moisture plants desire, so they SINK.

## Questions & Answers

**Q: Are people able to sprout in rock wool plugs, and then add these sprouts in plugs to one basket full of this ball media?**
A: Yes they are compatible, flush the hydroton clay media atleast 3 times with plain water before using in cultivation, or else your water is going to be disgusting from clay residue/dust

**Q: can this be used as a base in a saucer to sit a pot on in order to keep from sitting in water?**
A: You probably could do this in a hydroponic setup, but it probably wouldn't be the most effective use of the clay.  Each clay ball in the hydroton is a slightly different size, so it wouldn't make a very good base.  It's also fairly expensive just to be used as a support.This stuff seems to work best as a grow medium;  you could fill a flower pot with it, and it would probably wick water all the way up to the top.  It absorbs moisture really well.

**Q: where are they made?**
A: These are made of clay that is expanded in a special kiln making the pebbles more porous (and more capable of retaining moisture) than they would be if just fired at a low temp and a standard look  like a terracotta pot.

**Q: Is this 100% natural clay from nature? Is there coal slag in this?**
A: Not 100% natural. Yes it’s contain coal slag in it.

*by I***A on 5 October 2019*

As other reviews had mentioned, it is a relatively small bag for the price. However, I just needed a little bit to put in the base of my houseplants pots to help with drainage and this was a great amount for a few plants without too much left over. I have it filling the bottom inch or two of my pots with a layer of regular soil over top. They’ve helped immensely with drainage problems and mould that was growing on the old soil. I’m definitely no professional gardener but to help with a few house plants this is definitely a good bag.
