Hey folks first post on this forum. Was formally on rollitup but see alot of helpful info on this site so I may do the switch! So as of now I have 436 grams of 220 micron dry ice hash... I would like to make shatter! I've done multiple runs with my open blast tube but feel like this really needs a good soak! I don't want to invest the money into a closed loop just yet... I could turn my open blast into a closed column extractor... Or I could possibly do a butane thermos soaking the hash in the butane in a stainless steal thermos with the thermos sitting in dry ice keep it the coldest it can be. Do I have any other options? How long should i do a soak for? Thanks everyone!
