Most important freeze dryer data

This session covered the most important data points to track when freeze-drying hash and how to optimize recipes for different strains and equipment.

Key Data Points for Freeze Drying

• Ultimate vacuum: The most crucial metric to track - time spent at the lowest vacuum point

• Shelf temperatures: Important when considered alongside vacuum levels

• Cycle times: How long each stage of the process runs

• Batch variables: Tray placement, batch sizes, and resin types

• Input/output measurements: Recording wet weight in and dry weight out

• Moisture checks: Noting whether hash is dry during regular checks

Strain-Specific Approach

• Different cannabis varieties require different drying parameters

• No "one-size-fits-all" recipe works for all strains

• Final product quality should drive recipe adjustments

• Some strains may benefit from partial curing before washing

• Some resins may require different drying techniques

Freeze Dryer Equipment Discussion

• Comparison between Harvest Right and Holland Green Science freeze dryers

• Holland Green Science allows more precise control with 8-step programming

• Vacuum levels vary between equipment models and firmware versions

• Harvest Right has recent firmware updates (v6.0) changing vacuum behavior

• Programming recommendations for gentler vacuum ramping

Troubleshooting and Optimization

• Issues with incomplete drying may require adjusted recipes (in this case, we helped a HGS user change their recipe with more gentle ramping/vacuum pressures and longer steps)

• Temperature and vacuum ramping should be gradual to prevent terpene loss

• More gentle vacuum pressure can produce better results

• Tracking results consistently helps build strain-specific recipes
