Application fit is the starting point for any B2B substrate plug purchase. A seedling tray, orchid cup, tissue-culture rooting tray and succulent display product require different geometry and handling performance. Buyers should compare wet size, tray fit, hydration behavior, packaging route and monthly volume before requesting samples.
Match the plug to the growing workflow
Start with the dry and hydrated dimensions, cell profile and intended root-zone contact. A plug selected for a compact hydroponic holder may not suit a deep nursery tray, even when the top diameter appears similar. Ask how the sample will be hydrated, sown or planted, moved through the facility and transplanted. Record those conditions so different CF models can be compared on the same basis.
Buyer checklist
- Confirm application and target tray or holder.
- Request wet-size data and sample testing before bulk order.
- Clarify packaging format, carton quantity and monthly volume.
- Discuss SGS test report and export documents if required by your market.
