Enhance plant health
Give your plants the best conditions to grow and produce fruit by adding perlite to your soil mix or using it exclusively as your substrate. While earning more money on your crop, you could also save money on water and discarded unhealthy plants.

Improve root-zone structure and aeration with horticultural perlite
Healthy plant growth starts in the root zone. When the substrate is too dense, roots struggle to get the oxygen they need, and water distribution becomes harder to control. By adding horticultural perlite to your soil mix, you create more space in the substrate so roots can develop more freely and access oxygen more easily.
Our horticultural perlite is a lightweight mineral addition that does not degrade over time. It helps the substrate stay open instead of compacting, so you get more consistent root conditions across the growing cycle.
The imbalance of water, air, and nutrients results in unhealthy plants and poor yields
With perlite in your substrate you can achieve that balance and your plants will thank you for it.
Your plant roots require air, nutrients and water to thrive. In dry times, you want the substrate to keep the moisture and when it is time for watering, you want the substrate to shed the excess water to provide air to the roots. Our horticultural perlite helps to do just that.

Ensure effective drainage without drying out the soil
When you want to improve drainage, the goal is not to dry the soil out. It is to remove excess water fast enough to keep air available to the roots, while still keeping moisture in the substrate between irrigations. With perlite for your plants, you get a substrate that sheds excess water more efficiently without losing the ability to hold moisture where roots can use it.
Add perlite to your soil mix to make irrigation easier to manage and reduce the risk of waterlogged roots, especially when watering frequency changes through the season.
Use pH-neutral perlite to control nutrients and growing conditions
Stable growing conditions are essential. Our horticultural perlite is pH-neutral and chemically inert, which means it does not alter the natural pH of the growing medium or react with nutrients, fertilizers, or irrigation water. It gives you greater control over nutrient uptake and makes it easier to maintain consistent conditions throughout the growing cycle.
Because perlite does not interact chemically with the soil, it supports predictable plant nutrition and reduces the risk of unintended changes in the root environment. Whether you are working with sensitive crops, tailored nutrient programs, or long-term growing systems where stability matters, perlite is a reliable choice for soil improvement.
Perlite for flexible use across horticultural applications
Horticultural perlite is used when the substrate needs better control of air and water. It is commonly mixed into growing media to improve structure and drainage, but it is also used on its own in specific applications such as propagation and rooting, where consistent conditions are essential. Our perlite is suitable for both early growth stages and finished plants, making it a flexible material across different growing systems.
Whether you are working with propagation trays, pots, raised beds, or larger horticultural setups, perlite gives you a reliable way to upgrade how your substrate performs without adding complexity.
Make your green roof and green wall substrates lighter by adding perlite to your soil mix
- Thanks to the light weight of perlite, you can make your substrate solutions lighter and achieve your overall weight targets for your green wall or green roof project.
- Perlite is the preferred lightweight mineral addition to substrates due to its water-holding capacity of 5-6 times its weight.
Stable soil structure that supports long-term plant growth
Many substrates change over time. Watering, handling, and natural settling can gradually compact the soil, reducing air space around the roots and making drainage harder to manage. Horticultural perlite helps prevent that by supporting a more stable structure in the soil mix.
It does not break down in the substrate. Instead, it helps the soil stay lighter and more open, so root conditions stay more consistent throughout the season and from one cycle to the next.

HAVE ANY QUESTIONS
Is perlite more expensive than other minerals, e.g. pumice
Thanks to its light weight, perlite offers more volume per kilo than other minerals. This is why you should look at the price per metric cube rather than the price per kilo.
Is perlite the same as leca or pumice?
Not exactly. While leca and pumice are great additions to your substrate, perlite is second-to-none when it comes to offering quick water adsorption, aeration to the roots and a sterile and light-weight addition to your substrate.
Is perlite bad for the environment since it is produced with natural gas?
At Nordisk Perlite, we are using natural gas to create the flames with which perlite ore is expanded. The same heat is also used to heat up water for district heating and in this way, the environmental impact is minimized.
Do I risk infecting my plants with any illnesses by using perlite in my substrate?
Since perlite is inorganic, and because all potential organic material has been burned off in the manufacturing process, perlite is completely sterile and will not interact adversely with your plant roots or the nutrients you choose to add.
How much more fruit could I produce per plant with perlite against other substrates?
We have documentation that shows crop yield could be improved with as much as 46% using perlite instead of peat moss in tomato production.
