PVP Industries Medium Horticultural Perlite | 4cu ft - Medium - OMRI Listed

OMRI Listed Perlite for Plugs and Small Cells, Medium

Plugs, small propagation cells, and hanging baskets need a finer perlite grade than a full soil bed calls for, since a coarser grade can leave too much air space around a small root system. PVP Industries Medium Horticultural Perlite is graded specifically for that finer-scale use, sized for plugs, small cells, and hanging baskets.

This 4cu ft bag is OMRI Listed, staying stable over time without decaying, shrinking, or attracting pests.

Key Features & Benefits

• OMRI Listed — approved for use in certified organic production.
• Medium Grade — sized for plugs, small cells, and hanging baskets rather than large-volume soil beds.
• Clean, Sterile, and pH Neutral — won't alter the chemistry of the growing media it's mixed into.
• Non-Flammable and Non-Toxic — safe to store and handle without special precautions.
• Resists Decay and Pests — insects and fungi cannot break it down, unlike organic soil amendments.

Frequently Asked Questions

Is this perlite OMRI Listed?

Yes, it is OMRI Listed, which confirms it meets the standards required for certified organic production. That makes it an option for growers maintaining organic certification on their operation.

What is medium grade perlite used for?

It's used primarily for plugs, small cells, hanging baskets, and general gardening, where a finer particle size suits a smaller root volume. That finer grade blends easily into lightweight starter mixes.

Is perlite safe to handle?

Yes, it is clean, sterile, non-flammable, and non-toxic, so it can be handled and stored without special precautions. It also won't alter the pH of growing media it's mixed into.

How long does this perlite last in growing media?

It lasts indefinitely, since perlite is an inert volcanic mineral that doesn't decay, compost, or attract pests the way organic amendments can. That stability is part of why it's used across so many different growing-media blends.

What size is this bag?

This listing is a 4cu ft bag. Confirm the exact grade printed on the bag matches what your growing system calls for, since perlite grades aren't interchangeable in every application.
