Ultimate SOP: How to Use Dabpress 4T, 6T, and 12T Bottle Jack Rosin Presses

Pro SOP: Mastering the Bottle Jack Rosin Press (4T / 6T / 12T)
Maximizing your solventless yield is a balance of physics and patience. This SOP is designed to help you avoid "blowouts" and achieve consistent, high-quality results.
01. The Foundation: Humidity & Prep
•The 62% RH Rule: Flower must be at 62% Relative Humidity. Use Boveda/Integra packs for 24-48h. Dry flower = Zero yield.
•Pre-Pressing: Always use a Puck Maker. A solid, centered puck ensures even heat distribution and prevents bag failure.
•Load Sizing: Do not overfill. Leave 1/2 inch of space at the top of the filter bag for a "bottle-tech" fold.
02. Standard Operating Procedure (SOP)
1.Thermal Soak (10 Mins): Heat plates to 190°F (Flower) or 165°F (Hash). Wait for the heat to saturate the entire plate surface.
2.Contact Phase (60 Secs): Close the valve. Pump until the plates firmly touch the puck but do not apply pressure. This melts the trichomes so they flow instead of bursting the bag.
3.The Slow Ramp (60-90 Secs): Gently pump the handle once every 10-15 seconds. If the handle resists, wait. As oil flows, the handle will feel "softer"—this is your cue to add one more small pump.
4.Final Hold: Once maximum comfortable pressure is reached, hold for 60 seconds until the flow stops.
03. Technical Troubleshooting
•Issue: Bag Blowouts. Solution: You are pressing too fast or skipping the Pre-Heat phase. Patience is key.
•Issue: Dark/Burnt Oil. Solution: Lower temp by 5-10°F or reduce total press time. Freshness of material also dictates color.
•Issue: Press Won't Hold Pressure. Solution: Ensure the release valve is snug (not over-tightened). Check for air in the jack and perform a "Bleed" if necessary.
Expert Maintenance Tip: Never leave the plates under high pressure after the timer ends. Immediately release the valve to protect the internal seals of the bottle jack from heat-induced degradation.
CAUTION: DUAL HEATED PLATENS. KEEP HANDS CLEAR. ALWAYS OPERATE ON A LEVEL, STABLE SURFACE.
