Fantastic!!!!

November 9, 2016

Size: 40 Liter BagVerified Purchase

WOW, 40 liters is ALOT! LoL.
I have a rather large orchid collection (over 50 plants) I want to change over to these mixed with a little moss. fast shipping, nothing damaged. The bag came in a large box, nothing else. These pellets are not completely round or smooth, EXPECT odd shapes and sizes. The MUST be rinsed before use. I ran mine through water few times and gently rubbed all the pellets together. Right now I'm testing how long it takes to sink at the bottom of a jar, they are floating at the moment. I did re pot one smaller orchid and 💜. These are very light weight meaning....for my delicate orchids roots won't be damaged and will create good air pockets with out sufficating the roots. so far I'm in love...once Used more I will do another update.

Update 11/11/16. Been soaking 24 hours still float. This doesn't bother me but others it might. Will buy more if I run out.
New pictures of 1 orchid I re potted. Great stuff!!!

Update 12/09/16
Ok I forgot about some that where soaking, week later they where still floating!
For my use it's fine, but others may not like this.

Not round clay pebbles, basically clay colored gravel. Seriously.

March 31, 2017

Size: 10 Liter BagVerified Purchase

Nothing against the seller, they are simply a distributor and fulfilled the order. I have an issue with the product itself. I have purchased many different brands of clay pebbles over the years. These are by far the worst brand period. Here is why:

The Clay Pebbles are not spherical at all. I basically have a bag of clay colored gravel. I cut my hands on several pieces as I tried to fill the little net pots. That's absurd. There is so little clay baked onto the pebble that more of the burnt clay (the dark part of the rocks) remains exposed. This is not an aesthetic complaint. Clay pebbles were created and are favored by agriculturalists and gardners for a simple reason, they are easily washed and resused. However when the micro-pores on the clay pebbles are exposed, as in this case, the roots cling tightly to the pebbles, making them a permanent fixture in the root system ...without ripping them out. NORMAL round clay pebbles easily fall out when you shake the stalk. These are not re-usable and will have to simply be thrown out. And yah... they look like crap next to normal clay pebbles.

You can see in the image I provided, the poor quality, non spherical and mostly black rocks, compared to ACTUAL clay pebbles which should be 99% round.

Good stuff

February 26, 2015

Size: 40 Liter BagVerified Purchase

Bag says 'pre-cleaned' and I would say that's true compared to some other brands I've bought which left a lot of clay mud and small particles during the cleaning process. This left only brick colored murky water. As others have pointed out, they should be washed before use, at least in hydroponics applications. Put them in a 5 gal bucket with plenty of water, swish them around (toilet plunger is great for this), scoop out with a colander, rinse each scoop full with a hose, and you're done.
Maybe there is some variation during the manufacturer's bagging process where you could get a batch from 'the bottom of the barrel', I don't know.
The size description is accurate.
As to those who complain that they float, I say that's a good thing. After all they are porous and full of air, what did you expect? I doubt if you want the manufacturer to ship them to you pre-soaked with a lot of water - like that soggy compost you get in bags at the hardware, that's sold by the pound.
Plus, where are you putting them that they are floating around? Anyway they will soak up water over time and give your plants the combination of air and moisture that roots need.

10 liters is quite a bit - good pebbles

May 6, 2017

Size: 10 Liter BagVerified Purchase

If you are looking for perfectly round pebbles, like on the photo on the bag, look elsewhere. I read the reviews, so I was aware of what I was getting. Most of the pebbles were irregular shaped and looked like odd lava rock, but that does not affect my hydroponics system. I use a combination of hydroton in the bottom of each tier of the system and then in the grow baskets surrounding my roots. I used to grow directly in the tiers, in perlite, but I have always enjoyed hydroton, and this way I also have more control over the root system so that it does not clog my system. I just ordered a 40 ltr bag because 10 ltrs was only enough to make a short foundation in each of the tiers of one system. Since I completely switched over from Perlite this year, I need a lot. I soaked first (see picture of pebbles in the pink tub) and then I drained and strained. Towards the bottom, I strained and rinsed again in the strainer. A lot of mud and residue comes off of these, so be sure to soak and rinse before adding it to your systems. Obviously, I will check pH once I get everything set up for the plants, as I know that having this much hydroton will likely change the water balance, but that is okay. I also used this same brand in an aquaponics system, and I grew strawberries, mint and chamomile successfully. The hydroton did not bother the fish.

Great product for Aquaponic Grow Beds

November 15, 2014

Size: 40 Liter BagVerified Purchase

I bought 3 of these bags because 1.5 bags gets me 12" depth in a 3-4 sq. foot grow bed... and I have two beds. Overall, I'd say that these pebbles are working perfectly. They are pre-cleaned but definitely accumulate a lot of dust through shipping. You must wash them well. Lots of complaints about these things floating, and they are correct. I soaked them in water for about 30 hours and applied a board to submerge them forcibly. They kept floating. So then I decided to put them in little groups in a metal strainer and blast them with a shower head. This cleaned them off nicely, and when I put them back into the tub... VOILA no floating. So use a shower head and hit all surfaces. This is a long term product so a little start-up work is worth it. Yes there are some crumbled rocks and some tiny ones, but those made up less than 10% of the bulk and do not pose much of a problem as long as your siphon is shielded.
