Yes, you should store hash rosin in the fridge to maintain its quality and potency. Keep it in an airtight container, ideally with parchment paper to prevent sticking, at a temperature between 35-40°F (2-4°C). This slows degradation of cannabinoids and terpenes, preserving flavor and effects for months. Avoid freezing, as it can cause moisture issues, and always let it reach room temperature before opening to prevent condensation.

Optimal Storage Conditions for Hash Rosin:

Temperature: 35-40°F (2-4°C) in a refrigerator. Avoid freezing to prevent moisture buildup.

Container: Airtight, non-stick container (e.g., glass or silicone) with parchment paper to prevent sticking.

Humidity: Low, ideally 55-62% relative humidity. Use a humidity control packet if needed.

Light: Store in a dark place or opaque container to protect from UV light, which degrades cannabinoids.

Handling: Allow rosin to reach room temperature before opening to avoid condensation. Minimize air exposure during use.

These conditions preserve potency, flavor, and consistency for 6+ months.
