Rockwool is an insulation rock that has been used for decades to make homes more energy-efficient.
It’s also a wonderful hydroponic growing medium since it can hold water and air, which are required for plant growth.
If you’re wondering about the Rockwool’s composition and manufacturing process. This post will answer all of your questions!
How Rockwool Is Made?
- Rockwool is made from natural rock that is melted down and spun into a fiber.
- Basalt rock and chalk are put together and heated to a very high temperature. (approximately 3000°F) to form lava.
- The molten rock is then cooled and turned into strands, which are then chopped into small pieces.
- These small pieces are what we know as Rockwool slabs or cubes!
What Are the Different Ways to Make Rockwool?
Rockwool is an insulation rock made of rock that has been melted down and spun into a fiber. If rock isn’t rocking enough for you, there are other ways to make it.
The rock wool will come in various types depending on its temperature range, use for hydroponic growing, how absorbent it is, etc.
It can also be made from cinders or slag. These materials are heated up, then spun around to create fiber that can be chopped into pieces to form rock wool.
How to Choose the Right Rockwool for Your Use?
Rockwool comes in different forms and with different properties, so it’s important to choose the right type for your needs. Here are some things to consider when choosing Rockwool:
- First thing to consider is the temperature range that the rock wool can withstand. Some rock wools can only handle low temperatures, while others can handle high temperatures. Make sure to choose a Rockwool that will work with the climate where you live!
- Second, think about what you’ll be using the rock wool for. If you’re using it for hydroponic growing, then you’ll want to choose Rockwool that is pH-neutral.
- Third, consider the density of the rock wool. Heavier rock wools will hold more water, while lighter rock wools will hold less water.
- Fourth, think about how absorbent the rock wool is. Some rock wools are more absorbent than others, so make sure to pick one that can handle the amount of liquid you’ll be using.
- Finally, if you’re new to hydroponics and want to learn more about how it works, try using cubes. For most plants, cubes will perform well indoors. If there is no transplanting during the vegetative stage, slabs may not provide enough support. Lightweight wools are easier to handle because they are lightweight, whereas heavyweights give better anchorage and are less likely to float.
