Whats The Difference Between Dennerle Deponit And Laterite

[arif_93]

which ones better out of the two
which ones cheaper
does dennerle deponit need to be covered with gravel
where can i buy either

Laterite contains only iron.

Deponit contains a whole host of nutrients.

Laterite is cheaper. Deponit is more effective.

Both need to be covered with gravel/sand.

Tropica Plant Substrate is better still, and good value.
