What Size Rosin Filter Bag Do I Need?

The size of the rosin bag you need depends on several factors, including the type of material you're pressing (flower, hash, kief, etc.), the amount of material, and the size of your rosin press plates. Here's a guide to help you choose the right size:

1. Rosin Bag Size (Dimensions)

Rosin bags come in different dimensions to fit various rosin presses and accommodate different amounts of material. Common sizes include:

• 2" x 4": Suitable for small batches (1-7 grams of flower or hash).

• 2.5" x 4.5": A versatile size for medium batches (5-14 grams of flower or hash).

• 3" x 6": Ideal for larger batches (10-28 grams of flower or hash).

Tip: Choose a bag size that matches the width of your rosin press plates. The bag should fit comfortably between the plates without overhanging.

2. Micron Size (Filtration Level)

The micron size determines how fine the filtration is. Smaller micron sizes are used for finer materials, while larger micron sizes are better for coarser materials like flower. Here's a breakdown:

• Flower: Use 90µ to 160µ bags. Larger micron sizes allow more plant material to pass through, which can increase yield but may reduce purity.

• Hash/Kief: Use 25µ to 73µ bags. Smaller micron sizes prevent plant matter from contaminating the extract, resulting in a cleaner product.

3. Amount of Material

The amount of material you plan to press will also influence the bag size:

• Small Batches (1-7 grams): Use 2" x 4" bags.

• Medium Batches (5-14 grams): Use 2.5" x 4.5" bags.

• Large Batches (10-28 grams): Use 3" x 6" bags.

Note: Overfilling the bag can restrict oil flow and reduce yield, while underfilling may lead to inefficient pressing. Aim for a consistent, even pack.

4. Shape of the Bag

• Rectangular Bags: Most common and work well with rectangular rosin press plates.

• Cylindrical Bags: Used for bottle tech-style pressing, which involves packing the material into a cylindrical shape for more even pressure distribution.

5. Reusable vs. Single-Use

• Reusable Bags: Made from higher-quality nylon, these can be cleaned and reused multiple times. Ideal for frequent users.

• Single-Use Bags: More affordable and convenient for occasional use.

Final Tips

• Experiment: The ideal bag size and micron size may vary depending on your specific material and press. Experiment to find the best combination for your needs.

• Quality Matters: Invest in high-quality rosin bags to avoid blowouts and ensure consistent results.

• Bottle Tech: For flower, consider using the bottle tech method (packing material vertically in a cylindrical shape) for better yields and efficiency.

By considering these factors, you can choose the right rosin bag size and micron size for your solventless extraction needs.
