I don't know how accurate the temps are considering I can get visibile vapor below 2, if the chamber is fully loaded that is.
I don't know how accurate they are either, though it seems to be quite responsive, even to small adjustments. I mostly roast on 5, but I feel this is probably not the best way to vape for a few reasons.
THC has been found in vapour at 140°C, benzene at 200°C.
185°C is a bit of a sweet spot for THC extraction, but of course there are many more constituents to cannabis, so plenty of visible off gas isn't to be unexpected at lower temps.
I have witnessed heavy THC inhibition caused by a temp 2 toke, devil eyes and the mere ability to muster "this is good shiiit", but they had little to no tolerance. Nonetheless, an interesting observation given the 150°C setting, and the 157°C (most often cited)
boiling temp of THC at 1atm.
(you get steam at temps much lower than 100°C whilst boiling water on the stove, especially with a lid on the pot. Water vapour is gradually released until the excitement of the molecule is unhindered by the pressures exerted by the atmosphere, at which point the mass begins boiling (at a critical temp) and the steam is plentiful to the point of recondensation. It wouldn't surprise me at all if aeronautical engineers utilised pressure fluctuation in the general dynamics of their product, the instance of dragging on the device is enough to do it.)
So who knows how accurate the device is, but it does manage consistency when everything is working as it should. It definitely has better control fidelity than my EQ desktop too.
The key factor of the GH is that its heating element isn't required to heat up beyond the desired temperature, which leads me to think that its design offers the potential for extreme temperature accuracy. Of course there are many variables and no one has publicly taken one apart to scrutinise the inner workings, but all the theory is there and outlaid by HL, so yeah the grain of salt is sizeable but the jury is still out.
Meanwhile mine just died again, the body was replaced, then the back end, now I get red and blue flashers suddenly, though honestly it had been underperforming lately vapor production wise
That sucks, one of mine is on the way out too I'm guessing. Similar symptoms.
I've noticed that in the dying phase, performance either drops or increases. Having an "overclocked" hopper is an awesome time, before they break.
When performance swings the other way, it's just bad all round.
They've been holding out for way too long
Yeah, they have gotten away with actual protocol breaches. If there's one thing people should be pissed at HL for, that has the best grounds to be reasonably so.
It annoys me, and I'm not owed one, nor do I even want one.
They need to sort that out, and make a more durable product.
(or perhaps, make a more durable product, and then sort out non-essential accessories. In my mind though, and I'm sure many purchasers, the case and oils front-end are essential as they've been sold and promised already, they need at least some priority and to be properly addressed)
It wasn't all that long ago, in the grand scheme of things, where their initial pipe dream was as optimistic and doubted, so here's to hoping they can pull it together yet again.
just an update
