Bio activity and depth of substrate.

[Sloppysponge]

Just wondering what everyone is using for a substrate depth before the dranage layer.

Some questions, is deeper better (eg. 2ft vs. 4ft)

Does anyone use more dense soil in the bottom layers of substrate?

Or is it all one type of mix?


Thanks again everyone.

Vince.

shouldn't use any substrate. it will grow mold. bare bones on the bottom as possible
