Perlite - 4L Medium Grade
Perlite is used in soil mixes (including soilless mediums) to improve aeration and modify the soil substructure, keeping it loose, well-draining, and defying compaction.
The perlite can be mixed with a bit of potting soil to keep tall containers from becoming top-heavy, or the perlite can be used by itself as a bottom layer in wide oversize pots.
Roots will grow down into the perlite layer whether or not soil is mixed into it. You can also use perlite for propagation.
Zip Bag contain 4L of medium grade.
