Flirting with Combustion
I find just lowering the screen in a stainless tipped stem (Nong style) and then not packing material too high has made it so even my hot running dog can avoid charring without using a dimmer/VVPS. It still gets hot enough for that one hit killer. It seems there is virtually no visible vapor left once it's gone through the dog (or the dog has gone through it I suppose).Yeah since the latest revision I've had the temp pushed as high as I can without hitting the combustion threshold. That hot and they'll extract a load in just a hit or two a lot of times (varies depending on each kit and strains involved, etc).
EDIT: I do use an extension cord though.
