Perlite and Hydroponic Systems: What’s the Correlation?


What are Perlite and Hydroponic Systems? Perlite is a type of manufactured mineral which provides drainage for water and air. The heating of volcanic glass makes it to very high temperatures. This causes it to expand due to its heat resistance. The resulting foam-like material creates the ideal medium for growing plants in a hydroponic setup. It has a neutral pH and is chemically inert. That means it doesn’t add any nutrients or minerals to your hydroponic solution.

Glossary of standard terms when using perlite with grow systems:

Perlite is a type of manufactured mineral that provides drainage for water and air.

Hydroponic  – A type of growing system which works without soil. Plants are grown in water or aggregate such as sand and gravel.

Oxygenation – Introducing oxygen into the root zone, usually by ebb and flow or top feeding. This helps to prevent root rot and keeps the plants healthy.

Air stones  – Used in the ebb and flow hydroponic systems to provide oxygen for the roots.

Drain to waste – This is a form of hydroponics where the nutrient solution is drained away after each watering cycle; then recirculated through the system again. The plants are grown directly in the nutrient solution.

Low tech – A type of hydroponics system that doesn’t require complex equipment.

Nutrient solution – The water in a hydroponic system contains all the minerals and nutrients needed to support plant growth.

Grow media  – Substances used as a growing medium for plants, such as peat moss or perlite.

Why Use Perlite in Hydroponic Systems?

Perlite is a material made by heating volcanic glass to very high temperatures. These temperatures cause it to expand due to its heat resistance. This creates an incredibly light, open-structured growing medium that looks similar to Styrofoam balls. Thanks to its physical properties, it’s the ideal media for ensuring your plants have good drainage and oxygenation; promoting healthy, vigorous plant growth.

It is used most commonly for hydroponics systems; this includes drip irrigation and bubbler systems.

Perlite can also be used in soil-based growing systems; improving drainage and aeration but is usually more expensive than clay pebbles because of its lighter structure.

In Conclusion

Perlite can also benefit plants, helping them grow by adding air pockets and absorbing heat. Perlite is often used in hydroponics systems because it helps prevent root rot.

An ounce of weed is 1/16 of the pound; sixteen ounces make up one pound. So a half-pound is 8 ounces. One ounce of weed technically weighs 28.3 grams however, for a simple life, it’s rounded off to 28 grams per ounce. Now, since we are talking about half an ounce of weed, then, from this calculation, the weight is 14 grams.

  • A gram- the smallest weight you can buy
  • Eights- is ½ of ½ an ounce of weed- 3.5 grams
  • Quarter- ¼ ounce of weed or 7 grams
  • Half- half an ounce or 14 grams
  • Ounce- 28 grams
