I don't have any of those specific bubblers yet, unforunately. I just ordered the D020-D from sunshinestore but it'll be at least a month. I agree that hitting it upside down is better, especially for smaller amounts of weed, but I also want to be able to do this hands free, which is where the whip comes in. I've also tried taking the first hit or a few upside down with the whip and other stems. it seems to work for a little then it falls out, I think. I can't tell when it does or if it's when I'm taking the stem out.
I think my grind is medium and mostly consistent but I'm not sure. Why only two at each temperature? I like temperature stepping mode, but I also think it kills it too quickly. I can get more hits at each temperature without it, but I'm still not sure if it's really worth it, taking more hits at each temperature. I know the idea of terpenes and cannabinoids vaporize at certain temperatures, but I'm still confused on whether or not starting high does yield less effects in comparision, or if it just extracts it all faster.
I've noticed that sometimes I can keep going all the way to 430F and get results, though it's weaker and tastes worse past 400 ish. But sometimes it stops doing anything and just gets drier and browner. Same with the Mighty, but she stops it at 372ish because it seems cashed then. I know it shouldn't be like that.
I've had this for two months so I've had time, and I've gotten a lot better but yeah
