If you use soil contains perlite, you might need to monitor watering more frequently.
When gorwing plants in perlite, be aware that it may cause BROWN TIPS on indoorplants due to fluoride burn.
Due to perlite’s large surface area, it is a good choice for plants that require levels of high humidity. Evaporation off its surface area creates higher humidity levels that those of vermiculite.
【Benefits of Perlite】
- Improve aeration and modify the soil substructure, keeping it loose, well-draining, and defying compaction.
- Good choice for plants that require levels of high humidity. Evaporation off its surface area creates higher humidity levels that those of vermiculite.
【How to use】
- 15-20% mixed with soil to modify the soil substructure, enabling the pot to hold just enough water and oxygen.
