Short Answer

No, calathea cannot grow in leca.

Leca is a lightweight, clay aggregate that is used in hydroponic systems, while calathea prefers soil-based mediums.

Calathea needs soil to be able to absorb nutrients and grow, whereas leca does not contain nutrients and is not conducive to the growth of plants as it is a sterile medium.

Therefore, calathea will not be able to survive in a leca-based medium.

What is Calathea?

Calathea is a genus of flowering plants that belong to the Marantaceae family.

Calathea plants are popular for their beautiful foliage and are commonly referred to as prayer plants due to their habit of folding their leaves upwards in the evening.

They come in a variety of colors, shapes, and sizes and can add a touch of elegance and beauty to any indoor garden.

The most popular varieties include the Calathea Medallion, Calathea Orbifolia, and Calathea Makoyana.

Calathea plants are native to tropical areas of Central and South America and thrive in warm, humid environments.

They require bright indirect sunlight, moist soil, and regular watering to thrive.

What is Leca?

Leca, or lightweight expanded clay aggregate, is a type of clay pebble that is popular for use in hydroponics and other soil-less growing mediums.

It is made by heating clay to high temperatures, which causes the clay to expand and form small round pebbles.

The pebbles are then dried and packaged for use.

Leca is an ideal growing medium for many plants because it is lightweight, porous, and provides good drainage.

It also has the ability to retain moisture, which helps keep soil-less plants hydrated.

In addition, Leca is sterile, making it a great choice for indoor growers looking to avoid soil-borne diseases and pests.

All in all, Leca is an excellent choice for growing a variety of plants, including calathea.

Benefits of Growing Calathea in Leca

When it comes to growing calathea plants, there are many benefits of using leca (clay pebbles) as a growing medium.

Leca is lightweight and porous, which means that it provides excellent drainage and aeration for the roots of the plants.

It also allows for more oxygen to be available to the roots, which helps to prevent root rot and other diseases.

Additionally, leca is pH-neutral, which means that it wont affect the pH of the soil, allowing for more consistent growth of the calathea.

Leca also helps to keep the soil moist, which is important for calathea plants.

Calathea plants prefer consistently moist soil, but not wet soil.

Leca helps to keep the soil moist without making it overly wet, which helps to prevent fungal diseases and root rot.

In addition to keeping the soil moist, leca also helps to keep the roots of the calathea plants cool.

This is important because calathea plants prefer cooler root temperatures, which helps to prevent root burn and other issues.

Finally, leca can also help to reduce the amount of water that is needed to keep the calathea plants healthy.

Leca helps to retain moisture, which means that you wont need to water the plants as often.

This is especially beneficial in areas where water is limited or in areas where it is difficult to water plants.

How to Care for Calathea in Leca

When it comes to caring for calathea in leca, the key is to create the right environment for the plant.

It is important to remember that calathea prefers a warm, humid environment, so it is important to ensure that the temperature and humidity levels are maintained.

Additionally, leca should be used sparingly and should be mixed with a well-draining soil.

This will help to ensure that the plant is not over-watered and that it is able to access the nutrients it needs.

It is also important to keep the leca moist, as calathea plants are sensitive to drought.

To help maintain the moisture levels, it is recommended to mist the plant regularly or to use a humidifier.

Additionally, the top layer of leca should be changed every few weeks to ensure that the plant is not sitting in stagnant water.

Finally, it is important to fertilize calathea regularly to help the plant thrive.

The best fertilizers for calathea are those that are rich in nitrogen and phosphorus, such as fish emulsion or liquid kelp.

It should be applied at least every two weeks, at a quarter strength, during the growing season.

Overall, with the proper care and attention, calathea can be an enjoyable and rewarding addition to an indoor garden.
