Bought new toy with pressure meter.
Can someone tell me how much (how tight) can I fill it and what pressure should I aim for? And how long, 30 minutes?
 
Depends on what you are packing, but I pack bud broken into 1/2" chunks at the rate of 3.8 grams per cubic inch and 10 mesh at 4.1 gm/cu in column volume.

Unless you are subzeroing the column, soaking in a closed column extracts more non targeted elements like plant waxes, b-Carotene, and Pheophytin.
You are still open blasting, just increasing the soak time.

As far as pressure, zero pressure would be good, but depending on the LPG mixture, your pressure at ambient will be the same as the gas charts for that temperature and mix.

I bought this:

I bought this because I don't want use plastic DIY bottle and blasting butane through it. I've read with this method you can soak longer because you can close the valves, and thus getting more yield. It has PSI meter attached on top of the tube, so I wonder how much PSI should I aim for. I will not freeze tube, only starting material (trim and smaller buds) and butane.
