cindysid,
1st off best wishes to your husband and I hope your treatment kicks the cancer's butt!
Anyhow I agree with other responses that BHO made from cured herb would be more potent than quick dried herb....However I have made BHO from quick dried herb several times and I imagine the cannabinoid levels would be high enough for starting the treatment against the cancer (since I imagine you would like to flood his body with cannabinoids asap?). After harvesting I chopped up the pot (buds and sugar leaf) into small pieces and placed them on a roasting rack that I could place in the oven and everything would get good circulation. I then place it in a 170 degree oven for about 10 min. and shut the oven off for 10 min....then turn it back on to 170 for 10 min...and repeat the process until the buds are crispy bone dry...then stuff your tube and make the bho.
I also am curious if you are planning on decarboxylating either the herb or the oil after extraction since the oil is going to be taken internally and not for smoking?
I have been decarbing oil (I eat it for pain control) in the oven for 25 min at 250 degrees f and I obtained this time and temperature frame from this graph I found over on greenpassion.org -

Good luck with it all!
