Dennerle Plant Care Basic Root

I was a bit skeptical about clay-based tabs, but after a month my sagittaria finally stopped melting and started sending out runners. The roots are visibly thicker since I pushed these into the gravel near each plant.

My swords and crypts have really taken off since I pushed these clay balls into the substrate. The roots are visibly spreading through the gravel.

Dropped a couple of these clay balls under my swords and crypts two weeks ago, and the new growth is noticeably brighter and sturdier compared to before. The way they slowly release nutrients right at the roots seems to do exactly what it promises for established plants.
