Substrate culture system is a proven complete soilless growing solution. Instead of soil, it uses coco peat, rock wool and other substrates for tomatoes, bell peppers and flowers. The elevated troughs match drip lines and fertigation gear to control nutrient levels accurately. It avoids soil diseases and improves crop yield and fruit quality, widely used in film & polycarbonate greenhouses for overseas farms and seedling nurseries.
Main Components
Elevated grow gutters: hot-dip or fluorocarbon steel, resistant to nutrient liquid
Supplies: coco grow bags, rock wool slabs
Irrigation set: pressure-compensating drippers & filters
Fertigation unit: real EC & pH reading
Optional nutrient recycling pipes
Core Features
Less diseases: no soil means fewer nematode & root rot, no need for soil fumigation
Water and fertilizer saving: recyclable nutrients cut water use by 60% for steady growth
Easy operation: elevated design simplifies harvest and farm machinery work
FAQ
Q: What is substrate culture, and how is it different from soil or hydroponic growing?
A: Substrate culture uses an inert, porous growing medium (like coco coir or rockwool) to anchor roots and deliver water and nutrients. It offers the stability of soil while avoiding soil-borne diseases, and the precision of hydroponics without the need for constant water circulation.
Q: How often do I need to replace the substrate?
A: The replacement cycle depends on the crop and substrate type:
● For short-cycle crops, the substrate can be reused 2–3 times after sterilization.
● For long-cycle crops, we recommend replacing the substrate every 1–2 growing seasons to prevent nutrient depletion and disease.
Q: Can the system be integrated with automated irrigation or fertigation?
A: Yes, our Substrate Culture System is fully compatible with both manual and automated fertigation systems. You can link it to timers or sensors to deliver precise water and nutrient doses based on crop growth stage, reducing labor and ensuring consistency.
Q: Can we customize layout for my greenhouse size?
A: All trough lengths and layouts are custom-made to fit your house.
