Making rosin at home involves using heat and pressure to extract resinous material from plants.
Making rosin at home is a straightforward process that extracts concentrated resin from plant material using controlled heat and pressure. This method is popular because it avoids the need for solvents. The basic principle is to sandwich the plant material between heated plates and press it, squeezing out the desired concentrate.
Here are the key steps involved, based on common practices and the provided reference:
Materials You'll Need
Before you begin, gather your supplies:
- Plant Material: This could be flower, hash, or kief.
- Rosin Bags: Filter bags designed for pressing plant material.
- Parchment Paper: Non-stick paper to catch the expelled rosin. Avoid wax paper.
- Heat Source & Press:
- A dedicated rosin press (hydraulic, pneumatic, electric, etc.) for optimal results.
- A hair straightener for small-scale, low-tech batches.
- Collection Tool: A dab tool or razor blade to collect the rosin.
- Heat-Resistant Gloves (recommended for safety).
Step-by-Step Process
Follow these steps carefully to press rosin at home:
-
Prep Your Plant Material:
- Proper preparation is crucial for good yields and quality.
- For flower, ensure it's not overly dry or wet. A moisture content of around 60-65% RH is often ideal.
- Break up larger buds slightly, but don't grind them.
- If using kief or hash, you might pre-press it into a puck shape.
-
Add the Plant Material to Your Rosin Bag:
- Select a rosin bag with the appropriate micron size for your material (e.g., 90-120 micron for flower, 25-37 micron for hash/kief).
- Carefully place your prepped plant material inside the rosin bag.
- Leave some space at the end of the bag to fold or tie it closed.
- The bag helps filter out unwanted plant lipids and waxes, resulting in a cleaner concentrate.
-
Prep Your Press—or Hair Straightener:
- If using a rosin press, set the desired temperature. Flower is often pressed between 180°F and 220°F (82°C - 104°C), while hash/kief may be pressed at lower temperatures (150°F - 180°F / 65°C - 82°C) for terpene preservation.
- If using a hair straightener, turn it on to a medium-to-low setting. The temperature control is less precise, so practice is needed.
-
Place Your Plant Material Between Some Parchment Paper:
- Cut a piece of parchment paper large enough to fold in half and completely enclose the rosin bag.
- Place the filled rosin bag inside the folded parchment paper.
- Position this parchment paper "sandwich" on the heated plates of your press or between the plates of your hair straightener. The parchment paper prevents the sticky rosin from adhering to the press plates.
-
Press Your Material with the Press or Straightener for 4-30 Seconds:
- Apply even pressure using your press or firmly squeezing with the hair straightener.
- Begin with a small amount of initial pressure (a "pre-press" or "warm-up") for a few seconds to heat the material, then gradually increase pressure.
- Maintain pressure for the duration, typically 4 to 30 seconds, though pressing times can vary depending on temperature, material, and desired consistency. Lower temperatures often require longer press times, while higher temperatures require shorter times.
- You will see the rosin squeeze out onto the parchment paper.
After pressing, carefully remove the parchment paper from the heat source. Let it cool slightly, then use your collection tool to scrape the extracted rosin from the parchment paper. Store the rosin in a suitable container.
