4qt Hydroponic Clay Pebbles, 8mm-12mm, Toypopor Natural Organic Expanded Grow Media for Hydroponics, Drainage, Decoration, Aquaponics and Other Gardening Essentials

I didn't want to use soil for my microgreens so I thought I would try these. These make the whole process so much cleaner and easy. There is also less waste.

Value for money, size, color, quality and functionality of this product was great. Make sure you rinse them out well!!!All in all it great!

I went nuts trying to work out the volume of these to know how much to order. This bag is about enough for two dozen 3" net pots, along with a 1" rockwool cube. I soaked the pebbles in my nutrient solution before filling the net pots and nestled my (also soaked) rockwool cube in the top layer. The 3" pots fit perfectly in large mouthed mason jars, which I covered with a black sock to cut down on algae growth. I filled the jars with enough nutrient solution to reach the bottom 1/4 inch or so of the net pot (so the first layer of pebbles was submerged). My lettuce seeds are sprouting up nicely!

These are working great for my experimental Kratky hydroponics system. I've had great success with them growing Choi Sum, Lettuce, Green Onions so far. I'm using 2 inch cups for the plants and this is working well but I would like it more if the assortment of sizes included more of the smallest size. But I suppose that's because of the small cups I'm using. If I were using larger cups, I would probably think these perfect.

lookd good

I use these in plants but bought them for essential oils. A few of them on window sills with lavender and/or peppermint oil drops keep crawling bugs out. I freshen them weekly.

Works as described

There were quite a few that were broken. Other than that, they were fine

Après avoir décidé de changer la terre de mes plantes, ces perles d’argile se sont révélées être la meilleure option. Elles viennent en bonne quantité, et leur absorption et diffusion de l’eau est vraiment efficace. Mes plantes sont visiblement heureuses et commencent à produire de nouvelles feuilles ! Un produit pratique et qui fait vraiment la différence pour l’entretien des plantes d’intérieur.

Ok

At first, I was a little bummed looking at the size of the bag, but I got over that real fast when I realized how far this goes. I’ve been using this in the bottom of my seedling pots as additional drainage, as well as my bigger nursery pots too, as my little child helper (and I, too, if I’m being honest) have a bit of a heavy hand with watering at times. But this makes a big difference. I am loving the additional drainage and I couldn’t beat the cost. Even compared to other sites located overseas, this was a way better value overall!

The pebbles float in water as other people have mentioned. I have a bulgarian carrot pepper seedling sitting in a nutrient solution and I managed to fill a 4inch netted pot roughly half full with the pebbles. The roots are low in the pot and the pebbles are going up the stem about 3 inches. Hopefully this will be a sufficient ammount in order to stabilize the plant in the long run, but I doubt it. I also don't see these pebbles soaking up enough water to not float. I would look for a different product in the future. My Bulgarian Carrot Pepper in an experimental hydroponics system. A 2.63litre Simply orange juice container with duck take to block light using grotek precision: micro/grow/bloom and a tds meter to keep it at 1000-1200 ppm. Also using advanced nutrients up/down to control ph. Picture added after my initial comment. Roughly 1/3 of the pebbles are submerged in water. Roughly 1/2 of the roots are submerged in the nutrient solution. The other half of roots are open to the air. Mid 1/3 of pebbles are "floating" but creating a pocket of air beneficial to the plant in my system. Top 1/3 of pebbles are open to the air and for the first week+ since my comment, seemed to be wet. Tonight I added water and nutrients to my solution and brought the water up in the container so 1/3 on my 4" net pot is submerged again. I changed my mind, this product is working perfectly fine so far. A lot of info not about the product but giving you people details on my setup. I will update again in 1-3 weeks.
