Choosing the Right Pots for Your Leca-Grown Plants
When it comes to growing plants in Leca, choosing the right pot is crucial for their overall health and growth. Here are some things to consider when selecting pots for your Leca-grown plants:
The size of the pot you choose will depend on the size of your plant and how much room it needs to grow. Generally, you want to choose a pot that is slightly larger than the root ball of your plant. This will give the roots room to expand and grow.
The material of the pot can also affect the growth of your Leca-grown plants. Clay and terracotta pots are porous and allow for better air circulation, which can help prevent root rot. Plastic pots, on the other hand, are lightweight and inexpensive, but they don’t allow for as much air circulation.
Proper drainage is critical for the health of your Leca-grown plants. Make sure the pots you choose have drainage holes to allow excess water to escape. If the pot doesn’t have drainage holes, you can drill some yourself.
If you plan on using saucers under your pots, make sure they are large enough to catch any excess water. You don’t want the saucer to overflow and drown your plant.
While the colour of the pot may seem like a minor detail, it can actually affect the growth of your Leca-grown plants. Dark-coloured pots absorb more heat, which can cause the soil to dry out faster. Light-coloured pots reflect more heat, which can keep the soil cooler and moister.

One of the most important things to keep in mind when watering plants in Leca is to avoid overwatering. Since Leca is a porous material, it can hold onto moisture for longer periods of time than traditional soil. As a result, it’s important to allow the Leca to dry out slightly before watering again.
As a general rule of thumb, I recommend waiting until the top layer of Leca is dry to the touch before watering again. Depending on the plant and the environment, this could be anywhere from a few days to a week or more. It’s important to monitor the moisture level regularly and adjust your watering schedule as needed.
When watering plants in Leca, it’s important to use the bottom-up watering technique. This involves pouring water into the bottom of the pot and allowing the Leca to soak up the moisture. This helps prevent water from sitting on top of the Leca and potentially causing root rot.
To use this technique, simply pour water into the bottom of the pot until it reaches about halfway up the Leca. Allow the Leca to soak up the water for about 30 minutes, then pour out any excess water that remains in the bottom of the pot.
Since Leca does not contain any nutrients, it’s important to fertilize your plants regularly. I recommend using a balanced, water-soluble fertilizer and following the manufacturer’s instructions for application. Be sure to avoid over-fertilizing, as this can lead to nutrient burn and other issues.
In conclusion, watering plants in Leca requires a bit of patience and attention to detail. By following these best practices, you can help ensure healthy and thriving plants that will bring joy and beauty to your home or office.
