Excellent for orchids.

Reviewed in the United States on October 12, 2010

Verified Purchase

This is an interesting product that appears to be some sort of expanded, heat-treated rock or clay in the form of little balls. I potted one of my standard cattleyas in it and it is already (after only a week or 10 days) sending out huge, fat roots into the product. If you've had trouble with root rot due to soggy potting mix I would highly recommend this product; the little balls soak up water just like terra cotta or broken brick and then release it in the form of humidity so there is no sogginess at all. It also won't support insects like fungus gnats as an organic mix can. I understand that hydroponic growers also use this, but I'm just using it as a normal potting mix for cattleya alliance orchids. I do recommend soaking and rinsing it before use, because it does seem a little dusty. It is also surprisingly light and will actually float in a bucket of water, so you may want to use a heavier rock as a top dressing on the pot if you water by dunking your pots. Update: I continue to like this product really well. All of the orchids I've put in it have done well (with the exception of a very fussy C. aclandiae hybrid that doesn't really seem to like any potting mix I've tried.) Just be aware that you'll need to keep to a good fertilizing schedule since this product contains no nutrition for the plant. Also, I find it works best with terra cotta pots rather than plastic because the plastic pots can "sweat" and retain too much moisture. Update 5/28/12: This continues to perform. I especially like that I can repot without the tedious and often damaging picking of all the old mix off the roots. Since this isn't organic, it doesn't need to be removed. All I do is bash some holes in the old terra cotta pot with a hammer and then place the old pot--orchid, hydroton, and all--into the new pot with as much new hydroton as needed. The orchid will quickly send roots into the new hydroton while continuing to maintain its existing root system. So easy on both me and the orchid! If I am using a deep pot that might develop a wet spot at the bottom, I just put a big chunk of broken terra cotta at the bottom for extra drainage. If I am using a small pot that might dry out too quickly, I line it with some pieces torn from one of those coconut fiber hanging basket liners. As I write this, an orchid I recently repotted is sending out a fat new growth. That says it all. Buy this product.

Work well for my hydroponics

Reviewed in the United States on September 15, 2015

Verified Purchase

Many other reviewers stated that they received sub-standard knock-off product in their order so I will fess up and say that I don't know if I'd know the good from the bad. What I received seems perfectly acceptable. There is a range of sizes but not a very wide range, very few broken or mishap pen ones, and they do their intended job. I use them in net pots for hydroponic greens and they work well.

Decoration for Top

Reviewed in the United States on June 1, 2012

Verified Purchase

I am using this as a decoration on the top of the soil for indoor plant containers. I saw it in planters on a trip to Paris, hunted it down there, got the name, and ordered it from Amazon when I got home. I like how it looks. Sort of sixties retro. I agree with other reviewers that it is dusty when first taken out, but that was not a problem for me.

If you use it as I am, leave room at the top of the planter, so the balls are set low and don't roll out.

I will try it as a planting medium for orchids, but have not yet done so.

Best growing medium, be sure to rinse it out first.

Reviewed in the United States on December 29, 2014

Verified Purchase

Excellent growing medium for my leafy green aeroponic vegetables last summer. The clay pieces are completely solid, and hold just enough moisture for my timed water distribution. Just be sure to rinse the hydroton with water for about 10 minutes with a garden hose. There is a bit of powder that needs to be drained from the pebbles first if you're using a water pump, or don't want any silt clouding up your reservoir. This material works great for netty pots.

Great for Aquaponics

Reviewed in the United States on August 1, 2012

Verified Purchase

We purchased the hydroton for use in a small experimental aquaponics growbed. We mixed it with mixed-size riverstone gravel from the hardware store. We rinsed the rocks and the hydroton carefully before hooking up the system to protect the fish, and we never had any problems with dust/debris in the tank (aside from the normal.) It added bulk/depth without being too heavy, and gave the plants something to latch onto. We will definitely utilize it in future projects.

Genuine Hydroton quality grow media

Reviewed in the United States on June 19, 2016

Verified Purchase

Some other reviews are stating they received something other than Hydroton brand clay pebbles, but I'm happy to say I received actual Hydroton brand from Hydro Galaxy. These are perfect for my gardening needs, and cheaper shipped to my door than I could get them locally. They've been holding up great so far. They're not extremely dusty but be sure to give them a good rinsing before use!

Awful broken mess, do not waste your money

Reviewed in the United States on November 5, 2014

Verified Purchase

I received a bag of "mother earth" brand "clay pebbles," not the bag pictured in the listing. When I opened the bag I was startled at how dark the pellets looked compared to the Prime Agra pellets I normally get. The dark color turned out to be massive quantities of dark dirt and grit coating everything, probably originating from the 30% of the bag that is made of broken and crushed pellets. It may actually have been greater than 30% of the total bag, the broken bits were concentrated at the bottom and I finally threw the last two liters of material out in sheer disgust. And no, I don't mean pebbles with little chips here and there, I mean a pebble with half or more of it's original body broken off. When did it become acceptable for a company to produce a product that is 30+% useless?

If not for the fact that I was just given several nearly rootless 'rescue' orchids that need to be potted up semi-hydro asap if they're to have any chance of survival I would have poured it right back in the bag and returned it. It's definitely substandard quality and a waste of money since I'll only be anle to use half of it anyway, and then only after wasting an hour or more picking the broken pieces out.

I have to admit that I was completely surprised at these rocks. I had an phal orchid that was on the brink of death. I soaked these little rocks overnight, said a silent prayer and put my dying orchid in my clear starbucks cup via semi hydro method. Six months later, my orchid looks pretty good. Although it did not get any flowers yet, it so far has produced two flower spikes. Boom. Get a bag!
