  • Cheaper than the local Hydroponics store
Size: 40 Liter Bag
Clay balls. Some are crappy, but most are pretty much the same. It's compressed clay formed into a little ball. I opened my bad and was happy to find that my balls are symmetrical, some cheap brands are not. I probably could have phrased that better, but look, when it comes to clay balls get the most you can for your money, and these were a decent savings compared to the local hydro store. ... show more

  • Give me a thumbs
Size: 40 Liter Bag
I like these ones because they are small and I believe they can retain more water between the gaps because there is less space between them for air flow. They are good just like all the other and work the same way. Hopefully the images I took help you to Decide. The bags I have in the images is 25L and a 40L. the 25L filled up a 5 gallon bucket and the second one only 25% the way up. 40L filled up 2 5gallon buckets. ... show more

  • Not the same as previous purchase
Size: 40 Liter Bag
Overall this Leca does the job. If you’re looking for perfect spheres then this is not the right one for you. If imperfections are ok or this will not be at the bottom of the pot or you’re just looking for value then this is great. My only issue would be consistency within the product itself when purchased at different times. My first order had red clay while my most recent order had gray clay. ... show more

  • Excellent addition for potting plants
Size: 25 Liter Bag
These are great; large bag, good price, reduces weight, increases drainage. The only thing I don’t like is the brown water that comes out after watering. Even many months later after potting. And it stains concrete. I thought it would go away after a few waterings, but I’m still dealing with it as strong as the first time. ... show more

  • Great- as ordered
Size: 40 Liter Bag
The clay pebbles came mostly intact with only a few broken ones. The outside is more porous than previous brands I have used, but as it is a drainage layer for a bioactive terrarium, I think the texture of the surface will allow for more surface area for microbes and aeration, exactly what I wanted. I did need to rinse them before use as they were a little dusty, but that has been the norm for all the various brands I've used. ... show more

  • Sterilize Before Using
Size: 25 Liter Bag
When I started using this, the plants all got bad baterical growth in the water and rot the roots. No matter how frequently I changed the water. Started sterilizing the clay with a hydrogen peroxide bath before use and this symptom stopped. Otherwise works just fine. Note that the clay balls arent perfect spheres like other brands, they're just random blobs. ... show more

  • It functions properly !
Size: 10 Liter Bag
It works but I have to say that this is the fugliest LECA type product I've bought so far. It looks like Pooh💩💩💩. LOL!! But that doesn't matter as long as you aren't using it in a clear container, or you can top it off with a decorative substrate which is what I usually do.
