Soil & Substrates

The right growing medium makes a measurable difference to root health and yield. BlomSupply stocks quality cannabis soil South Africa growers rely on — including light mixes for seedlings, full-strength living soils, coco coir, perlite, and blended substrates — chosen to perform in both winter and summer grow cycles.

Substrate orders ship from Cape Town with nationwide delivery. We package growing media carefully to prevent bag damage in transit, so what arrives is what you ordered.

BlomSupply focuses on substrates with consistent pH buffering and good aeration structure. We know South African water quality varies by region, so we favour growing media that give you a reliable baseline regardless of your tap water.
