I am researching equipment to extend the shelf life of dried flower. This is all very new to me. So far I have seen systems that drop liquid nitrogen into a bottle, bottle then gets capped and a gas flush in tandem with vacuum sealers.
The Vacuum seal systems are affordable but crush the flower and cannot be used with bottles (which we have to use). Does any one know of equipment to dispense small amounts of liquid nitrogen into bottle I can use for in house trials that are low cost?
Thanks in advance!
