Leca, or Lightweight Expanded Clay Aggregate, is a type of inert ceramic material that is used in hydroponics and semi-hydroponics. It is made from clay that has been fired at a high temperature, which causes it to expand and become porous. Leca is a popular choice for growing indoor plants because it is lightweight, easy to clean, and provides excellent drainage and aeration.
Benefits of Leca
There are many benefits to growing houseplants in leca. First, leca is inert, meaning that it does not contain any nutrients. This makes it a great choice for plants that are sensitive to fertilizer, such as orchids. Second, leca is very porous, which allows for excellent drainage and aeration. This helps to prevent root rot, which is a common problem for houseplants. Third, leca is very lightweight, which makes it easy to move plants around.
Additional benefits of growing houseplants in leca include:
- Better drainage and aeration: Leca is very porous, which allows for excellent drainage and aeration. This helps to prevent root rot and other problems caused by overwatering.
- Less mess: Leca is much less messy than soil. There is no soil to spill or track around, and it is easy to clean.
- More efficient use of water: Leca holds water in its pores, which means that plants can take up water as needed. This helps to prevent water waste.
- Less pests and diseases: Leca is less likely to attract pests and diseases than soil. This is because it is not a nutrient-rich medium, which makes it less attractive to pests.
- Easy to fertilize: Leca is easy to fertilize. Simply add fertilizer to the water that you use to water your plants.
Getting Started with Leca
It is recommended to soak leca before using it. Soaking the leca will help to remove any dust or debris that may be on the surface of the balls, and it will also help to hydrate the leca so that it can hold more water.
To soak leca, simply place the balls in a bucket or container and fill it with water. Allow the leca to soak for at least 24 hours, or up to 48 hours if possible. Once the leca is soaked, it is ready to be used.

Tips for Growing Plants in Leca

- Start with a small plant. It is easier to transition a small plant to leca than a large plant.
- Use a pot or container that is the correct size for your plant. The pot should be large enough for the plant’s roots to spread out, but not so large that the roots will dry out.
- Use a fertilizer that is specifically designed for hydroponics or semi-hydroponics.
- Water your plants regularly. The leca should always be moist, but not soggy.
- Monitor your plants closely for signs of problems. If your plants start to wilt or drop leaves, it may be a sign that they are not getting enough water or fertilizer.
- Use a pot with drainage holes. This will help to prevent waterlogging and root rot.
- Clean the leca regularly. This will help to prevent algae growth and nutrient deficiencies.
