Growing Media

Common questions about this category

Answers for buyers sourcing growing media.

Which growing media is best for commercial fertigation?

For precise fertigation and EC steering, coco coir and stone wool are the usual choices. Coco holds more water and offers some buffering but needs cal-mag management, while stone wool is fully inert for the tightest control with disposal to plan for. Buffered media like peat and soil forgive lighter management but steer less precisely. Match the media to how often you feed.

Coco coir or stone wool for a commercial grow?

Both are favorites for high-frequency fertigation. Choose coco when you want more water holding and some buffering and can manage cal-mag; choose stone wool when you want a fully inert substrate for the tightest pH and EC control. Many facilities run both across propagation and flower.

Can growing media be reused between crops?

Coco is often reusable with proper handling and treatment between cycles, while stone wool is generally single use. Reuse lowers material cost but adds labor and pathogen risk, so weigh the tradeoff against your disease pressure and crop value.

How should facility buyers compare media for bulk orders?

Compare on landed cost, not the per-bag sticker: include freight, pallet minimums, water holding and EC characteristics, and consistency across lots. Confirm moisture at arrival and lead time so your first irrigation behaves the way your system expects.
