It's coming out a greenish brown vs a deep amber so I'm pretty sure I'm pulling chlorophyll. Is there a way to run this and get good results without cryo Temps? I only have viton gaskets atm and am cautious as hell. Am I to take what you said as packing the columns straight away then freeze? That's going to be a challenge seeing as the farm and I are 40 minutes apart. I can't see that being the answer.
Packing the buds straight from the plant into the columns and then freezing them would be ideal, but everyone has to make the best of their own situation. The amount of moisture that will condense on the buds also really depends on your relative humidity, air temp, and the exposure time of the bud. This might not be your issue, but I'd be willing to bet your issue is related to water content. Water in the tane will pick up more undesirables (aka chlorophyll and other polar molecules that darken the color). The ways to prevent this are by keeping the extra water from condensing on the bud during transfer, making sure your tane doesn't have water in it (if it's coming from a tank instead of a can), making sure the tane is cold and the bud is frozen, limiting soak time, and limiting the heat exposure to the oil/tane mixture during finishing processes.
If you do all those things correctly you should get blonde oil. It's already been mentioned, but tri-chome color plays a big factor into the color of your finished product as well. I would inspect the buds with a hand microscope to see the color of the trichomes. If they are already a dark amber color, the oil will keep that color (this will vary with strain type, process, crop time, etc). There are so many variables in this equation that it is hard to answer these types of questions without seeing every step of the process specifically.
Hope this helps!
