In the world of cannabis cultivation, "hold" refers to the process of preserving harvested cannabis flower for extended periods, aiming to enhance its potency and aroma. One crucial factor in this process is Initial Circulating Pressure (ICP). This article will delve into the significance of ICP in hold, providing a simplified explanation for both seasoned growers and newcomers.
What is Initial Circulating Pressure (ICP)?
ICP refers to the initial pressure at which air is circulated within a sealed storage container, like a vacuum chamber, during the hold process. This pressure is critical because it plays a direct role in:
How does ICP Work?
Imagine a closed container filled with cannabis and air. As the air pressure is lowered, it creates a vacuum effect, pulling moisture out of the flower. This controlled environment helps ensure that the drying process is gradual and even, preventing damage to the delicate trichomes and preserving their aromatic oils.
Optimizing ICP:
The ideal ICP for hold varies depending on factors such as the strain of cannabis, the desired level of dryness, and the specific equipment being used. Generally, a lower ICP (e.g., 15-20 psi) is used for initial drying, while a higher ICP (e.g., 25-30 psi) may be used for longer hold periods.
Conclusion:
ICP is an essential variable in achieving successful hold results. By carefully controlling this pressure, growers can influence moisture removal, terpene preservation, and ultimately, the potency and quality of their cannabis product. Understanding ICP and its role in hold allows growers to optimize their processes and create a superior product for consumers.

Scenario: You are holding a batch of cannabis flower in a vacuum chamber. The initial ICP is set to 20 psi. After a few days, you notice the flower is drying too quickly and some trichomes are becoming brittle.
Task: Explain how you would adjust the ICP to address this issue and why this adjustment would be beneficial.
To address the rapid drying and brittle trichomes, you would need to lower the ICP. This could be done by decreasing the pressure setting on the vacuum chamber. Lowering the ICP would reduce the rate at which moisture is drawn out of the flower, allowing for a more gradual drying process. This would help prevent further damage to the delicate trichomes and preserve their terpene content. A lower ICP would also allow the flower to reach a more optimal level of dryness without becoming overly brittle.
