🌱 Peat-free
Renewable plant fibres: high performance for your plants, peatlands stay where they belong.
💧 Light-Mix blend
Gentle pre-charge ideal for cuttings and seedlings. You stay in control of your feeding schedule.
🌿 Retention & aeration
500 mL held per litre, airy structure: roots colonise fast, perfect with fabric pots.
When should I start feeding?
The pre-charge lasts 10–14 days. At the first slight yellowing of older leaves, introduce a diluted grow nutrient (start at 1/4 dose, then ramp up).
Suitable for indoor LED growing?Yes — stable pH, low EC and an airy structure match perfectly with the short, intense cycles of horticultural LEDs in grow tents.
The right substrate is 50% of any indoor grow result: start with a clean, BIO-certified, peat-free Light-Mix.
