Semi-Hydroponic Plant Care

What is Semi-Hydroponics?

Semi-hydroponics is a growing method that uses LECA (Lightweight Expanded Clay Aggregate) instead of soil. Plants sit in containers with a small water reservoir at the bottom. The roots wick up water and nutrients as needed, providing a steady supply while reducing the risk of overwatering.


Benefits of Semi-Hydroponics

  • Healthier Roots – LECA provides aeration and reduces root rot risk.
  • Consistent Moisture – Reservoir ensures plants always have access to water.
  • Cleaner Growing System – Less mess and fewer soil-borne pests.
  • Reusable Medium – LECA can be rinsed and reused multiple times.
  • Easy to Monitor – Roots and water levels are visible.

Care Instructions

  • Watering: Keep the bottom of the LECA-filled pot just submerged in the reservoir so roots can wick up moisture.
  • Fertilizing: Use a hydroponic fertilizer mixed according to label directions.
  • Reservoir Maintenance: Empty and refill with fresh water and fertilizer mixture every 2–3 weeks.
  • LECA Care: Rinse LECA thoroughly between uses. If mineral buildup becomes severe, LECA can be boiled to loosen and remove deposits.
