When I started using nitrogen I thought it was gonna be harder. I like to think of it like how oil and water mix and they layer up. When I push nitrogen into my column I imagine it pushing the butane down kinda like wringing water out of a wet rag…then just burp it out…eventually youll get a feel for it…just keep an eye on your gauges have one on your column and one on ur pot and start with 50psi that’s worked perfect for me
