I bought two bags of this but it simply wasn't the right size for my needs and I ended up tossing them. The shipping was fast and service was great, but the product was not what I expected/needed.

Unfortunately, the mm size of clay pebbles I was buying was not listed in the description - I made the assumption that they would be the common size used for growing hydroponically (8-16mm). Upon opening the bag - I saw that they were very small (4-8mm, I believe) - I did try them out in my system anyways but most of them just all simply fell through my net-pots. I'll need to source 8-16mm elsewhere.

If 4-8mm will suit your growing needs - Go for it (Don't forget to soak them first) - But, if you're looking for a larger, more common size, these aren't it.

GrowDaddy, I feel that it would be helpful to future customers if the size of clay pebble being purchased was listed in the description to avoid further issues such as mine.
