CANNA CLAY PEBBLES HYDROTON
are what i,m going to use, i found it so so hard to find any here,. even online it was hard because they charge so much for shipping.
id love to know what people are using for their plants on top i have the coco pelt which i put my plants in after i washed them and all their soil off, but im not sure they can grow in just this?? what ar mothers doing.
also people who have a dam in a naturalistic one, how do they go with the water off the top plants seeping to the hydration layer and the dam. does it make the dam bad?
