i just got a closed column from best vac so its not just an open blaster...
The open refers to whether the butane is released to atmosphere, or recovered in a closed loop system, so even though your tube can be valved closed, it is still an open blaster.
We removed open blasting instructions from our site, because of the number of brothers and sisters ignoring the safety instructions, but left the safety instructions intact. May I suggest that you first read them at :

i have never done this before and i got everything in the freezer waiting for me to feel confident in what to do..lol....first question is since its not open blast, how long should i let the butane sit in the column? like a min? 10 mins?
What temperature is your freezer, and what provisions have you made to keep the columns cold during the soak?
When a solvent and a soluble are combined, the interface where they meet starts out highly active, but as both the solvent and the soluble at that interface each becomes less concentrated, a boundary layer forms where the reaction slows to a crawl.
Keeping the boundary layer removed, so that fresh solvent is in contact with the concentrated soluble, is key.
You can do that by flowing fresh solvent by it, or in the case of a soak, agitate the soak by shaking or vibrating. Check the picture of an early pressurized column experiment using a donated vibrator to keep boundary layers in check.
With that system, three minutes at ~0Fwas still good and after five minutes, we were electric green.
And I have watched a million and one vids on diff ways buy do you guys think after i let the nugs and butane marinate for a lil in the column, i should just relase onto a nostick mat in a pyrex dish and let sit in a water bath or just naturally evaporate and then heat purge at like 100 degrees??
When we were open blasting, we had our best luck discharging into a deep dish sitting in warm tap water. It should be deep enough to float out the atmosphere above the evaporation line, so that a layer of ice doesn’t form, and add water to your extraction.
Since its my first time i don't think i want to get into winterizing it and shit just because i dont have everclear and i dont want to wait a day or 2 before i can get lifted...oh anad lastly, tell me please if i understand correctly, to winterize, i have to do it right away at the same time im blasting, like mix the ethanol with the blast and freeze before filtering?? or can i make wax then in a day or two winterize it to make some shatter? i know i rambled and blew off all sorts of wuestions but anybody wanting to throw me some advice, it is much apprciated!!!
