Agree with most of this, but the Argo seems to be mostly convection. Also conduction seems to be very fast at extracting, although convection can be quick at higher temps.

It’s hard to say whether it’s more convection or more conduction. I suspect it has a lot to do with how you pack the stem. Fuller being more conduction, less full being more convection since your material is further away from the heater. All I know is the flavour is a lot closer to my Firefly 2 (convection) than my buddy’s Pax 3 (conduction), so I’m happy.

And I find that I’m getting medicated quicker with the ArGo than with the FF2, mostly due to the fact I don’t have to stir every few draws.

So... first you say the Argo is mostly conduction, then you say it’s mostly convection. Lol am I taking crazy pills? But yes, I agree it’s probably a mix of both, with the percentages changing somewhat due to how it’s used. And I agree the flavor and effects are great!

I didn’t say that! I just think the mix depends how you load it.

Grab the hot end of the stem, where the weed is, after a session and let me know if you still think it's mostly convection.

That herb really bakes in there if you ask me. It seems the outside of the herb is cooked darker (as is the bottom), but the middle is least cooked. The herb also tastes like conduction vaporizers, not convection. And the fact the session lasts as long as it does with so many hits is a tell tale sign of conduction if you ask me.

Not meaning to re raise this convection versus conduction debate, just making observations...

The blowing of stem to clear spent herb is what I think is not very discrete in public. I guess you can blow in your hand, but a pax for example you can just tap the herb out and load an unground nugget in less than a few seconds.

Good observation. I think if you watch carefully the top is 'less vaped' than the bottom part, I believe because heat is lost up the stem (slowly, but it has an effect)?

To me the key observation is, however, that heat soaks increase production (more time for heat to conduct in and replace that lost on the last hit. Convection, we would expect to be just the opposite? That is time between hits would cool the load meaning less vapor?

Here's an interesting test. Put a loaded stem in for say 2 minutes and let it 'heat soak' (all conduction, no convection) then take a hit? I get instant vapor, before any hot air could make it happen. The insert a fresh stem just barely past the seal and start hitting (full convection, no conduction).........

I'm not sure about being able to taste a difference, perhaps some can. But no matter how it's done, ArGo does it well.

Regards to all.

In case there are some micro dosers on this thread (who also happen to own HR dosing caps), you can use the ~9.5mm
Fury dosing cap as a limiter/container with the cap bottom facing in; a
Dosing cap in the top of the stem, acts as a slight heat filter, and a spare. YMMV

(Excuse the 60 degree display— slo to warm up. LOL)

Have you noticed if the dosage capsule scratches the bottom of the ArGo oven?

The metal on metal contact you'd think would help heat transfer and conduction

I doubt it, at least not to any significant degree (pun intended.....), probably not measurable, even?

Only the tips of a small fraction of the wires will make scant contact, and SS is a poor conductor of heat.

Overall I bet a very small factor considered to the slowdown of the normal conduction through the walls of the stem (by preventing direct contact between the glass and load? That is, overall I bet it's a loss heat transfer wise. But perhaps a plus WRT fast reloads or keeping it clean.

To anyone using HG2's in their ArGo, did you notice is difference in performance compared to the stock battery?

I dont know. When I lean a metal fire poker against a hot wood stove, the fire poker certainly gets hot even if only the pokers tip touches the stove....

Someone should grab the metal basket and find out...lol. not me!

I only noticed better battery life changing batteries .

The poker handle will never get as hot as the part contacting the stove, which is what we need to happen if we want to make vapor (the herb has to basically match the cup temperature), the shank is much thicker This means a big factor over fine wires because you have more surface per unit of cross section. And it's made of a better thermal conductor than SS

As I understand the rules of Thermodynamics it ain't happening. I'm betting better 'time to solid vapor' in the normal mode.

I can pull an Evo ELB out of that machine, barehanded after a session, and while I would not touch the bottom of the ELB, I can carefully touch the top and the cap. So makes sense; bottom of screen = hot, but top of screen = not so much. And weed is near cooler end, so screen actually hinders heating weed (versus having no screen).

Makes sense to me. Remember one of the rules is 'heat flows from hot to cold'. That means that all along that path the heat is dropping as heat lost to other places is removed. Like a leaking hose, as the water escapes on the way to the sprinkler, the pressure drops.

Anything the heat has to 'go through' (like the screen or glass walls) means the temperature on the other side drops.

Everything will be cooler than the cup, hopefully not much cooler.

So screens above the load have a different effect from those below.
