Greetings,
If anyone is interested, there is a very simple hack that can be done in making RSO/FECO that has huge ramifications on quality. I've spent the last three years developing this and am publishing it for free, for everyone to use. This simple change will take the Total Cannabinoids from the mid 30s to high 70s. Now, you can take 2oz cured plant and have vape-able decarbed winterized oil in under 2 hours. Here's the demo video.
Remember, nothing for sale, its all free.
You can choose what alcohol to use. I use Isopropyl for the bulk extraction. 95% Ethanol works fine, but costs more. If you don't have access to 95% Ethanol, then you can use Isopropyl for the bulk and 100 proof vodka for the final reduction. The magic here is adding Distilled Water to the initial boil down. By doing that, you removed the water soluble compounds leaving purer non-polar cannabis oils. This is then winterized by a highly optimized room temperature winterization. I actually use the freezer for an hour just to make it more robust. And you know the best part? No lab gear, filter setups, vacuum pumps. Use only the gear in the kitchen, just like the video. If you know how to make RSO, then you'll know how to make this oil.
Cheers!
