Tomatoes are a long, high-demand crop. The root zone has to deliver steady moisture, plenty of oxygen and a stable, low EC so the plant can be steered from vegetative to generative growth. Washed, buffered cocopeat gives growers that control from the very first irrigation.
What tomatoes need from the root zone
Tomato roots need a balance of water-holding and air-filled porosity that stays consistent over a 9–11 month crop. Salts must be low and predictable so your feed — not the substrate — sets the EC at the root.
- Stable, low starting EC for clean nutrition control
- Good air-filled porosity to avoid root suffocation
- Even re-wetting for uniform irrigation across the bag
Recommended cocopeat mix
A 70/30 pith-to-chip grow bag suits most tomato crops, balancing water buffering with drainage. In hot climates or with high-frequency fertigation, a 50/50 blend adds extra air and drainage to keep the root zone oxygenated.
Irrigation note
Pre-wet bags thoroughly, then irrigate little and often, targeting 20–30% run-off during the day to manage EC. Monitor drain EC/pH to steer the crop.
