A reduced-oxygen cannabis curing protocol built to help preserve aroma, character, and handling stability beyond conventional air-based workflows.
Oxygen exposure can erode the value of carefully grown flower. Conventional air-based curing leaves aroma, freshness, and stability vulnerable during the post-dry phase.
Conventional burping introduces fresh oxygen into the vessel and can accelerate loss of volatile aromatic compounds over time, flattening the profile of the finished flower.
Repeated oxygen exposure during post-harvest handling may contribute to cannabinoid and aroma drift, reducing freshness and moving the product away from its intended profile.
Poorly managed post-harvest conditions can leave flower tasting grassy, harsh, or prematurely faded instead of allowing a cleaner, more deliberate cure to develop.
Our method uses inert-gas displacement and controlled venting to reduce oxygen exposure during cure while allowing evolved gases to be removed without repeated exposure to room air.
Displaces atmospheric air in a substantially sealed vessel to create a reduced-oxygen environment during the most vulnerable post-dry phase.
Allows evolved gases to be vented and refreshed with inert gas during the cure interval, reducing the need for repeated room-air burping.
We monitor RH rebound and stabilization behavior to compare lots, refine purge timing, and build a more repeatable cure protocol.

"Weed should be so good you’d smoke it even if it didn’t get you high — and because it’s that good, the high is even better."
Mike Johnson’s relationship with cannabis started long before legalization, shaped by a respect for flower that values patience over shortcuts. After years in Napa Valley tasting rooms, surrounded by producers who obsess over preserving delicate aroma and character, he saw a clear parallel in post-harvest cannabis.
While the wine world uses advanced stabilization to preserve volatile character, the cannabis industry has largely been left to subjective guesswork and atmospheric drift.
Johnson Curing & Consulting was founded to explore a more disciplined post-harvest path. No gimmicks. Just gas physics, closed-vessel handling, and side-by-side validation aimed at preserving the expression of the harvest with greater consistency.
Current pilot work focuses on aroma retention, RH behavior, and side-by-side product evaluation under reduced-oxygen cure conditions.
The goal is straightforward: compare your current cure against a reduced-oxygen protocol using the same starting material, then evaluate the difference with real observations instead of marketing language.
A single harvest lot is divided into matched portions so the conventional cure and reduced-oxygen cure begin from the same material.
One side follows your standard workflow. The pilot side is sealed, flushed with inert gas, and refreshed on a scheduled purge cycle.
We document RH movement, recovery behavior, purge timing, and practical handling observations throughout the interval.
Finished samples are compared for aroma, freshness, handling stability, and overall sensory impression to determine whether the method deserves further scale-up.
This is not aimed at commodity throughput. It is for teams that believe post-harvest handling materially affects the final product and are willing to test that belief seriously.
Producers who already put real effort into genetics, dry room discipline, and small-lot presentation.
Brands looking for a post-harvest edge that supports premium positioning rather than just cheaper storage.
Operators open to controlled comparison, note-taking, and iterative refinement instead of one-off guesswork.
If the goal is pure volume and speed at any cost, this probably is not the right conversation.
Pilot work is evaluated through a mix of sensor data, handling observations, and side-by-side sensory review. The point is not to pretend everything is solved. The point is to create a repeatable basis for scale-up decisions.
Recovery after purge, stabilization trends, and whether the material behaves more consistently under reduced-oxygen handling.
How much character the lot retains through cure and holding, especially when compared directly against a conventional air-based control.
Practical observations around freshness, feel, vessel behavior, and whether the cure appears easier to preserve into packaging and storage.
We are currently seeking side-by-side pilot partners interested in evaluating reduced-oxygen curing against their existing post-harvest workflow.
