Fertilome | Perlite 8 Qt

Fertilome horticultural perlite in an 8 qt bag. Perlite is a mineral that's heated until it pops, leaving light, white particles. Mixed into potting soil, it opens up air space and lets water drain through faster, so the mix holds less water.

It's inert, sterile and pH neutral, so it changes the texture of a mix without changing its chemistry.

Tip: dampen perlite before mixing to keep the dust down.
