Yes you can use live rosin 2 turn 2 oil. After I press I cold cure my rosin in the fridge.
Clear Glass Jars with Black Lids… Amazon.com
I use this hot top
Aroma Housewares AHP-303 Single… Amazon.com
I place my rosin in those jars so If I want 2 press I will put 1g in a Har after I press it. Once the jar gets warm the rosin is liquid so let it sit there until it boil which is decarbing.
I put the oil in the syringe while still warm and straight to the cartridge
No the oil do not come thru the vape I really love it better than dispensary.
I found these 2 be the best 1s in my opinion it hits so smooth and taste amazing.
