Hi Again,
I have managed to get my dried bud and trim to an 8% moisture content. I was told that moisture impacts co2 extraction efficiency. What is ideal moisture content? How and why does moisture reduce my extraction efficacy ? Thanks for all advice.
Less than 10% is ideal, water adjusts the polarity of CO2 as a solvent during extraction, making it more polar. This leads to chlorophyll and other undesirables coming along in the extraction.

so the increase in polarity will attract the chlorophyll and drag it and the other polar nasties out thus reducing the quality of extract? I think I now understand. First one who explained it clearly, thanks.

Can it be too dry for CO2?
I don’t think so. Typically Co2 extractions use material that’s decarboxylated. All the material we extracted was under 5 percent usually 1-3 percent. Decarboxylated bud is more efficient for extraction as well. Removing the carboxyl group on cannabinoids allows for the co2 to bind to them more effectively

obliged. Drying my harvest now and it is pretty dry.
Are you processing it with co2? My understanding you can extract cbda and thca but I believe it takes longer and you need super critical pressure. We ran ours for 2hrs for decarbed thc material and 2.5 hrs for cbd
Not sure, I need to toll it out for extraction and I was just trying to remember how moisture played with the extractions, CO2 and Ethanol. This is our first grow.
Ive been toying with the idea of drying it in a vac oven but afraid to damage the biomass. Any thoughts?
