How exactly do I use my E-pic to measure the load? And my ABV has been green or black, not brown like I want it to be. What kind of draws should I take?
Also, how exactly do I move my screen?
Move your screen with a pencil or chopstick. This will allow you to push it from either end, even on a dry stem.
Plenty of great advice and tons more throughout this thread. Though I think just all the replies to you in the past page or so should get you started pretty well. Skim the thread for many more tips. Check the video in
this post for a good tutorial of small load, close, with fairly low temp on a bubbler. This works well with dry stem, too (just turn heat down about 1/2). Plenty of other good tips down in that part of the thread. Keep in mind that different nanos in different situations will have different temp settings - and that's before we even get to personal preferences.
Make sure you give it enough time to properly warm up. 3 - 5 minutes on 10 and turning it down to preferred temp for a couple minutes works OK, but to get best performance out of nano you want it all the way warmed up. 20 to 25 minutes (or 10 - 15 after setting 10 warm up) should get you there.
Try turning your heat down some. Start at 6.25 - 6.5 if going through water. Try 6 - 6.25 if using dry (just stem). You can always turn it up to squeeze more vapor out, but once you go at a higher temp it's pretty pointless to turn it down on that load. I prefer to stay in the lower to mid-range temps, but you may like it hotter. Try both to see what you like, but IMO if you're charring - you're too hot. When I'm going for flavor and headier effects, I'm usually below 6 if dry. You don't necessarily need to exhale big clouds to get good and stoned.
How much you load is going to affect how much vapor you get, too. But, if you're using about .05 - .07 a load, you should be able to get at least 2 or 3 good hits - maybe even 1 or 2 more after a stir.
One thing I haven't seen mentioned is quality of your material. Any vape is going to require pretty good stuff to do much. It's not like combusting where you get everything out of it (good and bad and the brain numbing effects of any smoke). With vaping we only really consume the top end of compounds (lower temp generally the "higher"/headier compounds), so if there are less of them there you'll have less there to vape.
Also, if you haven't vaped much be aware that it is a bit different of a buzz and usually comes on differently.
Hang in there and play with it. I'm sure you'll get it soon if you haven't already.
