How to use it?

- Verify the humidity level of your flower is at least 60% stable in your jar before committing to the next step.
- Carefully break down your flower into smaller pieces, approximately 0.25-0.5 grams.         
Tip: Using nitrile gloves will help keep your essential oils off of your hands when handling flowers.
- Place the base of the mold on top of the working table.
Line the base of the mold with a small sheet of parchment paper to prevent essential oils from sticking to the base.
- Place the rectangle shell over the base of the mold.
- Evenly distribute the material inside of the shell until you have your desired amount loaded.         
Tip: Use the PETP spacer sheets for lower amounts loaded to form a more compressed puck.
- Place a sheet of parchment paper over the loaded material to prevent sticking to the mold.
- Place the plunger inside the rectangle shell and compress it onto the working table using the palm of your hand.
- Remove the mold from the base and turn it upside down to see the base of your compressed puck.
- Eject the puck from the mold and quickly load it into a 2x4” or 2x4.5” filter.  
Tip: Dabpress brand filters include a plastic sheet that can be used to hold open the filter for easy loading.
- Fold the remaining unfilled portion of the filter over the top of the puck.
- The puck is now ready to be pressed using your heat press machine.

Important Notices!

- If more than hand pressure is needed to compress the mold, we recommend a hand clamp vise to assist you.
- Loading more than the high amounts suggested may result in blowouts of filters.
- Included PETP sheets are included to help you create a compressed puck with lower amounts loaded.
- If using a shop press or arbor press to compress the molding, be sure to protect the top of the mold with a wooden block to prevent damage to the aluminum.

Questions & Answers:

Question: What are the recommended minimum amounts loaded?
Answer: 7g using included PETP sheets
Question: Can I compress the pucks using my arbor press?
Answer: Yes, though be careful not to apply too much pressure onto the aluminum surface directly. 

Question: What Humidity level should my flower be stored in?
Answer: 62% is the recommended stable relative humidity (RH) inside of your flower container

Question: How to measure the humidity in my flower container?
Answer: A small hygrometer will give you the humidity levels inside the container. 

Question: Can I re-press my pucks?
Answer: Yes!  Simply fold the puck in half and re-press it.  You might have to use a higher temperature to get an extraction. 

Question: Do I need to use filter bags for flowers?
Answer: No, you can press single flowers and get great results, you can also use the pre press molds to form pucks to press without the use of filters.  Keep in mind when not using filters that the puck will expand a bit larger.


1 - How to avoid the filter bags from blowing out?

- Remove excess stems from flowers.
- Use less material in your filter bag.
- Preheating your material first to get it melty before you begin to apply pressure.
- Apply the pressure more slowly.

2 - How to apply the pressure for optimal yield and quality?

- Flower is the easiest material to extract. Slowly compress the puck until the oil begins to flow. As the extraction is flowing, it is important to keep some weight of downward force on the jack handle to maintain that level of pressure in which the oil is releasing. By applying too much pressure we may experience blowouts, or even introduce plant matter into our essential oils. Once the puck is mostly extracted you should no longer feel any more release of pressure on the jack handle.
- Sift and fine material will take some practice, so we advise you to preheat your puck between closed platens. They need to only touch the top and bottom of the puck for preheating. No pressure is required.  Allow the puck to preheat for 20-30 seconds. At this time the puck should be melty and more likely to flow out instead of building up pressure inside which may cause a blowout. Gently apply pressure onto the puck and give it time to release the oil, slowly applying the pressure throughout the entire extraction. 

3 - The yields are not very good.

- If pressing the flower, verify your sealed storage jar’s humidity level is between 60-65%
Try a different variety.
- Sifting or hashing it first will allow you to press out a product with acceptable yields.
