What extraction method will you be using? Freezing alcohol. Basically similar to Rick Simpson's hash oil extraction, except instead of boiling off the alcohol you freeze the extract and remove the alcohol. Any tutorials or are you just using Rick Simpson's vid? I just got a high CBD strain from my breeder. As far as extracting tobacco, I am using a bunch of info I found on the ECF. I have tried extracting oil from buds using RSO methood. I found it to be less desirable than BHO. Safer, perhaps, but not worth it. It was runny and loaded with plant material. My yeild was greater, but the potency and flavor was not as good. If you want more info on RSO and freezing impurities out of RSO look at fuckcombustion.com. But I suggest using butane, 3X purified. I don't know of any better method than butane, just do it in ventilated area and not near any sparks.
