LECA 2L Bag
LECA - Lightweight Expanded Clay Aggregate.
Use LECA instead of soil to grow your plants in! Roots easily grip to the substrate and reduce the risk of root rot compared to in soil. Just fill your pot with water to just below where the stem of the plant sits - don't cover the stem as this can cause it to rot. Add fertiliser to the water once a month and that's it!
