How do you guys hit your hopper? I just did a loose full pack and took 4 pulls on 2.5 temp and then a few on temp 4. I thought I read somewhere that if you do too many hits on the lower temps it's "wasting" THC.
I'm not really sure enough is known about vaporisation to really know what is the best method overall.
And trial-and-errors are difficult with cannabis.
With glass:
I find in order to get the biggest, thickest clouds, straight to 5 is best.
This gives a knock-out punch, to some degree.
For finer, higher quality vapour try 3-4.5
I find this is tastier, but restricts the possibility of getting hyper-dense clouds.
The effect it offers seems more psychedelic and less sedative, but this could entirely be caused by less active chem exposure rather than a chem spectrum difference due to temperature limitation.
For flavour, 1-2 definitely offers more terps, flavos and much less THC concentration ratios.
I think, the key thing is there is a lot of THC per weight in quality cannabis.
A lot of THC is going to be wasted when blowing out big clouds, which the GH is basically tuned to.
However, in terms of getting the maximum onset from cannabis consumption, optimally you would want the highest concentration possible in as quick a time as possible.
Every toke from this point will have less of an impact due to natural tolerance (desensitisation to the relevant receptors).
And so rather than "wasting THC" with lower temp initial runs, as long as the THC is collected, you simply are just reducing the amount of desired chemicals from that particular sample (herb in the chamber) lowering potential off-gas concentration and lowering the maximum potential intensity of hit from that sample.
However by obtaining the conditions to get the most potent hit, you need to literally waste more THC by lack of lung absorption and exhalation.
You could catch this in a bag and re-breath it several times to limit this too.
*edit: there would be a timeframe that would allow for additional intake without tolerance affecting potency. However I reckon this would be pretty short, I remember reading once that with DMT it was 15 seconds, however DMT is one of the fastest acting substances (hence its short duration) perhaps with THC, being that the peak lasts ~12 times longer it could be as much as a few minutes of lee-way.

On powerbank time-out, if another device is connected you can still get constant power.
Additionally my powerbank (Rapoo p500) has an LED torch that can be activated to sustain power, and you can notice when the current is shared as the LED starts blinking. After this I have found if I turn the torch off, the GH will still charge.
Ultimately, get a USB powered dual Li-ion cylinder battery charger and you are set!
