Why make oil with your buds,
maybe the moldy ones, but save your buds for smoking
, and use what is left along with any males to make the oil.
Just don't use the roots ( I was told not to use them as they may make you sick ).
I have tried the butane way and I find it OK, or so so; but I am going to try this way (below) this week with some males that I am drying out. Waste not-Want not...
Step 1
You'll need to chop up your weed and pick apart the buds until it looks like grass clippings. Remove any seeds, they have their own oils which we don't want. Dump the powdered pot into the mason jar and pour in just enough grain alcohol so the weed particles float freely in the mixture. Place the lid securely on the jar and shake a few times.
Let this mixture sit for a few hours, shaking it every once in a while. The alcohol should have turned a dark green color and when shaken should form colorful, oily bubbles on top.
Place the sturdy cloth over the metal container and press the cloth down to form a funnel. Carefully pour the contents of the mason jar onto the cloth which is in the metal cup. Make sure to get most of the weed particles out of the jar. Gather up the edges of the cloth and squeeze the remaining liquid out of the lump of weed into the metal cup.
Step 1
You should now have a quantity of dark green liquid in your metal measuring cup. It is possible to extract more THC oil from the remaining pot. I recommend performing Step 1 a second time immediately after completing it the first time. No sense throwing away the good stuff. Dump the pot from the cloth back into the mason jar and repeat step 1. You now have twice as much liquid in your metal cup upon repeating the first step.
Step 2
Be sure to use an electric stove in this step! I am going to use a hot plate out side away from anything (because it will burn down your house if you are silly)
Take the metal cup containing the green liquid over to the stove. Turn one of the electric eyes on LOW setting and place the metal cup on that burner. I highly suggest using the fan over the stove to remove the alcohol vapors during this entire step. Watch the liquid closely. It should only boil slightly, never raise the burner temperature above MEDIUM LOW. We need the liquid to cook down until it's slightly thick. This may take some time but be patient.
Once the liquid starts to thicken and turn darker, remove it from the heat.
Never let it get too thick or it'll be too difficult to work with. If you do accidentally make it too thick, just add a small quantity of the grain alcohol to the metal cup and swirl it around till it's thinner.
Let it cool down to room temperature inside the metal cup. It should be runny enough to be poured into the bottle easily. You now have your final product: THC oil. It's necessary to have some grain alcohol left in the resulting liquid so it's easy to work with. This will not affect the potency of the oil.
Once it's evaporated test to see if it's too thick. If it is, pour a small amount of grain alcohol in the metal cup and mix. Pour the liquid into your bottle.
