Well, I'm still not exactly where I want to be but I am getting a little closer with each step.
Almost all the black is gone, now and it's turning to a nice dark amber color.
HEAT...... gotta have HEAT. LMAO
I vac'd it over and over and for different periods and, although it would get a little bit better, I wasn't going anywhere fast.
The hot water dish helped but, very little. However, I definitely did notice a difference. Keeping hot water is a PITA.
I scrapped the water dish and put the vac chamber right on the seedling heating pad. The pad itself gets about 103. I put a thermometer in the vac chamber so I could monitor the temp inside the chamber.
It was real steady at about 100 degrees. At the -28.9 Hg, I think that's well below the 190 degree temp that the THC evaporates at.
I smoked some and it was an instant rush, which was nice. Still too sticky for me. I can roll it in a ball or a "hot dog" and it's pretty easy to manage but...... still not crispy. LOL
What have we learned this time:
Gotta have heat.
Start with cleaner oil.
Couple tips for next time. I have been using a 100u screen. That's a lot of matter getting through. I ordered 50u screens. That should get some of the gunk out right from the get-go. I'll also try unbleached coffee filters.
I could also try the "winterizing" [is that right] process. Adding Everclear and then doing another evap. I don't really like that idea but, I'll try anything once.
I'll post a pic as soon as I have something that shatters.
