Perlite #4 Large - 4 Cu Ft

Looser Media and Better Drainage - 4 Cu Ft Bag

Compacted, waterlogged media starve roots of air. Perlite #4 is a lightweight, porous amendment that opens up potting mixes so water drains and air reaches the root zone. Its large, bulky particles support drainage, aeration and nutrient uptake, and it is sterile and contaminant free.

The 4 cu ft bag suits regular indoor growers who mix media in batches, and it gives small commercial operations a practical unit for amending or hydroponic use. It is sold as a single bag.

Frequently Asked Questions

Q: What is Perlite #4 used for?
A: It improves drainage and aeration in potting mixes and helps prevent compaction. You can also use it alone as a hydroponic medium or for starting cuttings.

Q: Will it change my pH?
A: No. It has a neutral pH, so it does not push your mix toward acidic or alkaline.

Q: Can I use it by itself?
A: Yes. It works as a stand-alone medium in drip systems or as a mix-in with other media, especially for plants that need fast drainage.

Q: What does aeration mean?
A: Aeration is the amount of air held in the spaces of a growing medium. Good aeration lets roots take in oxygen and lowers the risk of rot.

Q: How is it sold?
A: It is sold as one 4 cu ft bag. Orders have a minimum order quantity, which does not make it a pack.

Q: Can it ship by ground?
A: No. This product does not ship ground and is available only from the California Distribution Center.
