Good evening, and thanks for taking the time to stop by. I recently purchased a 90g Dewaxing column with the “pro” upgrades from BVV. We have a vac pump, vac chamber and a 20(16)# butane tank. We have been testing with some gifted trim the past 2 days and I feel like I am missing something. I am working with a buddy who has been open blasting with cans and a homemade tube for years, and this setup is new to him. We are not freezing the butane or material, this was some material donated for the purposes of testing and getting used to the system.
My questions right now are, what is the proper way to introduce the butane? How much psi should the column reach? Should I let the butane flow through, or let it soak? If soaking, how long? We have been getting a consistent color with each blast, however, I feel like there is a lot of air/pressure blessing out of the column after the liquid stops flowing.
Any and all tips are greatly appreciated.
