Hey brotherman!
I was JUST checking to see if there is a Volcano Thread.
I too have the solid valve digital!
From my research I have concluded that different cannabinoids (with different effects) are released/vaporized at different temperatures.
365F-392F is the cannabinoid spectrum.
365F is basically THC
378F is like CBN
392F is CBD
(I'm either getting CBN or CBD confused I'm not sure)
Either way, for best results this is what I do:
Grind your herb into a FINE powder. - - that orange grinder they give you works pretty well but beware of the plastic breaking off.
Don't put a LOT in there, put enough to cover the surface area of the screen - - - (you can put in more and get more fucked up but usually a small amount does me in just fine)
Turn the Volcano to 365F, put the chamber on there with NO bag attached.
Once the chamber is on there, turn the volcano to 372F, and then press the green button to start it, wait a second or two and then attach the bag.
The volcano will slowly go from 365 to 372 as it inflates the bag. Then I do 372 to 378, then the how many bags more I do depends on how much is left.
I find that having the temperature changing during inflation results in a smoother, more full bodied high. There is NO problem with running it at a single temp, my recommendation is just from experience.
A few things:
Preheating: Well, the cannabinoids wont begin to evaporate until the substance itself is heated to the correct temp. When You put a cold chamber on the volcano and turn it on you will notice how vapor doesnt come out for a few seconds, before that it's just air. Well personally I like as much vapor in my bag as possible. So before I attach the bag I let it run for a second or two. You can also let it pre-heat by letting the chamber sit on top of the volcano for a few minutes, but letting it run without a bag is the quickest/easiest.
Volcano hash: All that sticky brown shit that collects on the volcano is basically hash, solidified THC vapor. You can scrape it off some parts fairly easy and smoke it. Most of the substance gets collected on the little metal cone thing that screws into the bag mechanism (you'll see when you clean your volcano) Be careful it FUCKS you up.
Other than that I can't think of anything really. Dis-assemble the parts and clean with alcohol. Try to keep the screens clean; the more airflow the better.
Any questions just PM me, I've been using the Volcano Digital since November of 2009. It's a very simple device. A lot of stuff is learned by using it and figuring out how to make it the most efficient. The beginning is alllll experimentation, so enjoy that man. Remember you might not get as high at first because you don't know how to use it to it's full potential. It took me a little over a week to COMPLETELY figure it out but that's because I was doing it on my own
