Aloha,
Long story short. I love dabs and had expressed interest in making it. Voila! I had a turnkey closed loop setup with vacuum ovens given to me along with a steady supply of trim. My problem? Dark oil. I need to know what causes it to be so dark. I would like to see more honey color. What I always get is opaque when thin and up against light but it's always dark. I've learned that starting with really dry material is key to making the end product stable at room temp but I can't figure out how to produce anything other than this dark shatter or snap. Call it what you want. I have no problem with it being this consistency but the color isn't pleasing.
Butane tank is 63 lbs when full. It sits in an ice bath. I generally flush with about 15 to 20 lbs. using a digital scale. Straw valve flows into condenser coil also in the ice bath and then out to top of 4' column flushing oil into a bucket sitting in a hot water bath. Butane then flows out of the bucket into a desiccant dryer and is compressed and returned to the tank by a recovery pump after going through another condenser coil in the ice bath. I pull a vac on the entire system before I start the dump and I wait until the same vac is pulled by the recovery pump before emptying the oil onto trays and putting them in a vac oven at anywhere from 95 to 110 degrees F and as close to 30 inches of vacuum as I can get.
I have tried variations of oven temp, time exposed to butane (one dump or 2), but I've never been able to get a light color product.
I know that the material you start with is important but I've had all kinds. Fresh bud to auto trim. It's driving me crazy trying to figure this out. Please give me your ideas.
I tried to upload a pic but the site is having issues.
