Approve an acclimatization plug only after the buyer has tested tray fit, wetting, humidity transition, plantlet handling and transplant observations under its own protocol.
Map the transfer workflow
Document the plantlet type, vessel removal process, washing or preparation step, tray geometry, humidity-management approach and target transplant stage before selecting samples.
- Identify the point where plantlets enter the plug.
- Record whether loading is manual or automated.
- Note the current media format and the reason for comparison.
Confirm tray and plug geometry
Share the cell count, top and bottom opening, depth, taper and drainage layout. Check both dry and hydrated fit because seating and removal can change after wetting.
Control the acclimatization comparison
Use plantlets from a defined batch and apply the same environment, irrigation and observation schedule to the current medium and candidate plug. Record any treatment differences rather than assuming they are equivalent.
Track transition and handling observations
At agreed dates, record visible plant condition, plug surface condition, root-zone handling, cell removal and transplant observations. These operational records help distinguish media fit from changes in humidity or irrigation.
Move to a line trial before recurring supply
After bench screening, repeat the selected format across the intended tray and normal nursery workflow. Confirm the model, approved sample reference, packaging, destination and documentation scope before bulk procurement.
Buyer evaluation matrix
| Evaluation area | Controlled input | Record |
|---|---|---|
| Plantlet source | Defined batch and preparation method | Batch and transfer date |
| Tray fit | Measured cell geometry | Dry and hydrated fit photos |
| Humidity transition | Buyer acclimatization schedule | Setpoints and changes |
| Irrigation | Same method by treatment | Volume, timing and drainage |
| Transplant handling | Normal nursery sequence | Removal and root-zone notes |
Send the crop or application, tray dimensions, current workflow, destination, expected volume range and required evidence with the inquiry. MCCS sales can then discuss the most relevant sample and evaluation route.
