One bag, one full tent. This Gold Label substrate blends 80% clay pebbles (8-16 mm) with 20% chunky coco fibre, RHP certified: pre-washed, pre-buffered with calcium, ready to use. Fill your pots, hook up your drip system, and grow.
- Express drainage — the 8-16 mm grain size flushes excess water in seconds, ideal for frequent, short watering cycles in hydro
- RHP certified — Dutch professional standard: stable coco, controlled EC, compatible with drain-to-waste and recirculating systems
- 45 L = 4 to 6 pots of 7-10 L — enough to fill a 1.2×1.2 m tent with a single bag
- Grower tip — Avoid compacting the substrate when filling your pots to maintain proper root aeration.
