Perlite #2 Extra Small - 4 Cu Ft

Lighter, Better-Draining Mixes - 4 Cu Ft Perlite

Dense potting mixes compact over time, which slows drainage and starves roots of air. Perlite is a lightweight amendment that opens up the mix, improves drainage and aeration, and supports strong root development. This grade is sterile and has a neutral pH, so it adds structure without adding unwanted ingredients.

The 4 cu ft unit suits regular indoor growers who blend their own mixes, start cuttings or run small hydroponic setups. Each unit ships at 29 lb and measures 16 x 36 x 9 in. Orders have a minimum of 15 units, and the unit is sold each.

Key Features & Benefits

• Improves drainage and aeration — keeps the root zone from staying waterlogged.
• Helps prevent compaction — supports root development during vegetative growth and flowering.
• Neutral pH — will not push your mix toward acid or alkaline.
• Sterile and contaminant free — a clean starting point for propagation.
• Single ingredient — perlite only, with nothing added.

Who Should Use Perlite #2 Extra Small

Growers who mix their own media, start cuttings or seedlings, or run hydroponic systems will find it useful. Small commercial operations can also use it as a consistent amendment across batches.

Frequently Asked Questions

Q: What does perlite do in a potting mix?
A: It improves drainage and aeration and helps prevent compaction. That gives roots more air and room to develop.

Q: Can I use it without soil?
A: Yes. It can be used alone as a medium for hydroponics or for starting cuttings.

Q: Will it change my pH?
A: It has a neutral pH, so it should not shift the pH of your mix on its own. Test your finished mix and nutrient solution as usual.

Q: Is it sterile?
A: It is listed as sterile and contaminant free. Keep the bag closed and your tools clean to preserve that.

Q: Is the 15-unit minimum a pack size?
A: No. The product is sold each, and 15 is the minimum number of units per order.

Q: How does perlite differ from vermiculite?
A: Perlite mainly adds drainage and aeration. Vermiculite is generally used where more moisture retention is wanted.
