Construction perlite is a lightweight, porous material commonly used in building and construction projects. But can it be used for plants? Many gardeners and horticulture enthusiasts wonder if construction perlite can be a suitable alternative to horticultural perlite.

The answer is yes, you can use construction perlite for plants. However, there are a few factors to consider. Construction perlite may not be as pure as horticultural perlite, and it may contain impurities that could potentially harm plants. It is recommended to rinse construction perlite thoroughly before use to remove any impurities.

Additionally, construction perlite may have larger particle sizes compared to horticultural perlite. This could affect water retention and drainage in plant pots or containers. Adjusting your watering and drainage practices accordingly can help mitigate any potential issues.

In conclusion, while it is possible to use construction perlite for plants, it is essential to be aware of the potential differences and take necessary precautions to ensure the well-being of your plants.
