i've gone through a couple oz of shatter or wax through my herbie and i always used a little bud with the shatter. when i first tried the concentrate pads, they tasted terrible, even after a few soakings in rubbing alcohol then water.
i got 8 grams a couple of days ago and finally tried it without weed. the pad taste has gone away after many grams of use (i have 6 pads and they all tasted the same. nasty.)
i love it. a very nice high used all alone. go figure.
i've tried going to 445 for bud and concentrate and i can't deal with it even though water. i go 400 to 415 degrees and i usually get 2 full bags for each .05 of shatter.
i splurged and tried a .1 bag full. ima do that some more.
i got these for $25 a gram in stead of $40.
my top screen gets too sticky after 4 bags full. love it.
next sale of shatter i'll get more. i'm curious to see how long 8 grams lasts. i'm retired so i vape when i feel the urge. the urge is strong.
i have an omnivap that i haven't tried with shatter. i'll have to fire that up after i come down a bit.
@MileHighHuman - very good questions. here's how i do it.
1 or 2 aroma pads - 2 pads mostly. sometimes i just throw some on top of some ground bud.
Oil only or Oil+flower combo - until today, it was oil + flower. this was due to the shitty taste of the pads. i will still do some concentrate + flower but i'll be doing much more shatter/oil only now that the pads don't add a crappy taste.
Fan or no fan assist - always use the fan.
Bag, Whip, or Steamroller - i use the bag 97.5 % of the time. i usually vape from the bag through a bubbler via a long whip.
Temperature - i go back and forth on temp. sometimes i'll stay at 380 for days and sometimes i'll stay around 400 for days then 410. for daytime and i don't want to take a heavy nap, i'll stay around 380 depending on the genetic.
Inhalation speed - slow on whip and bag.
Size of dose - typically .05 for bud and .05 for shatter. i think it's better to do 2 bags of bud at .05 per bag than one bag at .1. i'm pretty sure i get more mileage that way.
edit:
i just realized that when i'd go to 430 to 445, i always had bud in the bowl. just did .1 of shatter only at 430 and it's pretty smooth. i take small sips but very little irritation. nice.
some of the pads have taken a beating. ordered 4 more pads and 24? new screens. that'll give me about 35 screens .
