The high carbon steel sheet may include a fine pearlite having a lamellar structure.

For growing cannabis, “fine” perlite is the preferred option.

The fine pearlite included in the high carbon steel sheet may have a volume percentage of larger than about 90%.

When buying perlite, three grades are available: fine, medium, and coarse.

Expanded perlite coated with a composition to render the perlite impervious to water, and a joint compound incorporating the same.

The coatings comprise perlite and/or expanded perlite that are activated with hydrophilic agents.

The composition contains no pearlite compositions.

In one aspect, the additional perlite fines can comprise at least approximately 3.5% perlite fines by weight.

The material has a ferrite-pearlite structure.
