Perlite Coarse #3 Small - 4 cu ft

Coarse Drainage and Aeration for Healthy Roots - 4 cu ft

Dense, compacted media holds too much water and starves roots of air. Perlite is a lightweight amendment that opens up potting mixes so water drains and air reaches the root zone. Its large coarse particles help prevent compaction and water-logged roots, and the material is sterile with a neutral pH.

At 4 cu ft per unit, this size suits growers who mix media regularly, from home gardeners blending batches to small commercial rooms filling containers or hydroponic systems. Orders carry a minimum of 15 units, so it fits growers who stock up.

Key Features & Benefits

• Large coarse particles — improve drainage and aeration around the roots.
• Sterile and contaminant free — adds no unwanted ingredients to your mix.
• Neutral pH — leaves your nutrient and pH program undisturbed.

Who Should Use Perlite Coarse #3 Small
