How long can you keep plants in LECA?

Repotting: As your plant grows larger, there will be a time where you need to repot it. Remember, LECA is an inorganic material so it will never break down like organic potting mix. General rule of thumb for soil grown plants or bark / moss grown orchids is that the medium should be replaced every 1 - 3 years.

Do plants in LECA need to sit in water?

Plants in Leca essentially water themselves. The clay balls absorb water from the bottom up, yet remain full of oxygen at the same time thanks to all those tiny bubbles of air created when the clay was baked (like an Aero chocolate bar), so roots can take up only what water they need, with less risk of root rot.

Do plants do better in LECA?

Leca balls allow for more aeration as the air pockets between the clay balls allow more oxygen to reach the plant's roots. This prevents a well-known gardening disaster: root rot. Leca pebbles can be used for almost every kind of plant.

Why are my roots rotting in LECA?

Prolonged exposure to a wet environment will cause root rot, which causes the plant to decline in health. When prepping a plant to be moved into LECA, its best to clean off the organic materials as best as you can. This will allow the plant roots to make direct contact with LECA.

Can plants in LECA get pests?

Back to top When you're using Leca, rather than soil, you'll be much less likely to have to deal with pests. This is because of the simple fact that roots are less prone to root rot in Leca than they are in the soil. When soil is too wet for too long, it'll start to rot and it'll take the roots of your plant with it.

Should roots touch water in LECA?

With plants in soil, if you water them before they're ready, you risk them getting root rot and dying. We don't have that issue with leca, so long as the roots aren't submerged (and many plants are happy to have their roots at least a little submerged).

What happens if you dont soak LECA?

Science Stuff: Why shouldn't you use dry LECA? It's because LECA wicks water very effectively. If you have roots come into contact with very dry LECA, it will wick water away from the roots and can cause the roots to desiccate. Always make sure they are well soaked before use.

Can plants grow big in LECA?

Plants that are able to grow a large root system quickly Plants that grow a root system quickly are the most likely to succeed in Leca. These types of plants usually spread their root system to look for moisture to absorb, which they'll easily be able to find in the clay balls.

Why are my plants not growing in LECA?

Unfortunately, you can't grow any type of plant in Leca. Plants that have very thin roots (succulents, cacti, etc.), plants that need a lot of nutrients from the soil (Crotons), and plants that need moist soil (Peace Lily) don't do very well in Leca.

Can you grow plants in LECA without nutrients?

Keep in mind however, that unlike soil (which is fully organic), LECA does not contain nutrients. This means that any nutrients your indoor plants need, will need to be manually added to the plant's water using supplements.

Can I use tap water for LECA?

So to answer the original question…can you use tap water for hydroponics? Yes, yes you can – if you treat it properly beforehand! If it has a high PPM, consider running it through a filter or mixing in distilled or reverse osmosis water to dilute the concentration.

Does LECA increase humidity?

Our LECA stones are a great way to increase humidity levels. Place them at the bottom of your decorative pot, underneath the grow pot. The pumice is highly absorbent, which not only prevents water from pooling in the pot, the absorbed water is retained by the pumice, increasing humidity around the plant.

How do you prevent root rot in LECA?

7. Rotting roots

Rotten roots: trim the rotten roots and place the plant in just water. Observe for root growth and/or new water roots.
Rotten bulbs: trim the rotten roots and rotten bulb parts. Let the bulb and roots complete dry. Re-plant and keep the water level right below the bulb to keep it from rotting again.

How often should you water plants in LECA?

Regular Watering Regularly watering LECA plants is super easy. Most plants that are 6-inches or less require watering just once every 2 to 3 weeks. Simply add the water directly to the reservoir/bottom container. That said, keep an eye on your LECA and re-hydrate them with water if they become dried out.

What houseplants do best in LECA?

Alocasia.
Aloe.
Bromeliads.
Coleus.
Hoyas.
Orchids.
Monsteras.

Can fungus gnats lay eggs in LECA?

LECA balls absorb water and still allow good aeration to plant roots. Because they are hard clay fungus gnats aren't able to lay their eggs in them. The downside to LECA is that you need to add all the nutrients your plants need into the water, which are usually naturally present in soil.

Can you get fungus gnats with LECA?

The last myth I am going to bust with LECA is the claim that there are little to no pests when using LECA. Again, this is not true. Even though there is no soil, one can still get all the houseplant pests, even fungus gnats—which seems to be a driving factor to people switching away from soil.

Is it better to propagate in water or LECA?

LECA, or Lightweight Expanded Clay Aggregate, is a good alternative to just using water as the pebbles will stabilize the plant, deliver more oxygen to your cuttings, and enable them to grow without being exposed to light, so that the transition to the soil is easier.
