TUBO evic/dual

[Abysmal Vapor]

@funkyjunky all this talk about heat soaking material has me confused.

I KNOW and have tested my convection "on demand" vapes MVT, Milaana, Boundless CVF. The material (cannabis) does not get hot unless there is heat going through the cannabis (drawing).

IF ha vape has conduction and convection that is a hybrid heating system.

Please @funkyjunky clear this up.

Thanks.

Heatsoaking the heater not the herb dude ! The temp read you are getting is the temp of the coils ,not the air nor the surrounding materials.Tubo heater is consistent of 3 tubes with coils inside. The air gets heated by contact both the coils and the glass tubes. Heatsoaking is mainly getting the glass tubes hot,so the heat mass can gather up,this will result in smaller temp drops..
As far as i remember this was cleared by FJ the moment he introduced the cruise mode... He said something like , Hot tubo is a good tubo and also compares function to log vape..
In a log vape you want the heater well heated so you can have more stable temp/ hits ...
I can compared the preheated tubo vs the from cold to a performance of a log vape heated for 5 minutes vs for 30 minutes.
Cruise mode is not different than on demand,it is like the software is holding the button for you and long fire protection is off..,but overall is more gentle on the battery, cause it will drain less wattage over longer period of time,which i think is easier for half drained battery than delivering shorter busts of higher wattages ) !

@Abysmal Vapor how do I set my cruise to a different time?

U press fire button and + to get into the menu > vaping > Prot. set to XXX seconds.
@sickmanfraud Hey buddy i think this great post of vapen00b will clear things up for you!

@funkyjunky Thanks a ton for your fantastic support and firmware update!


I made some temp measurements in regards to conduction/radiation.


First experiment: probe all the way down into female joint touching the internal mesh screen. (As if your material would have fallen onto the heater screen).
Cruise mode running for 120 seconds, set temp 220C from cold (.195 ohms coil resistance).

Spoiler: Animated gifs - Mesh temp at bottom of the bowl

START

AFTER around 60s

AT THE END (->120s+)

Results:

Temps at the mesh that would conduct heat to the load, if it sat right there (without airflow, no movement):
-around 140C after 1 minute
-169C max. after 2 minutes



Second experiment:
Probe installed in the center of the male joint at the end, nearest to the heater screen (w/o airflow, no movement).
Cruise temps, time, resistance, everything the same as before.

Spoiler: Animated gifs - Temp inside joint closest to the end

START

AFTER around 60s

AT THE END (120s+)

Results:
-around 45C after 1 minute
-around 62C after 2 minutes
--> max. temp afterwards was 63,3C due to residual heat moving up - unit has auto-shut off by then (around 20-30 secs after cruise ended)



TL;DR: Fantastic properties... Convection FTW!!!


Enjoy your on-demand/session style full convection tubos!!

I think you nailed it! We're lucky to have so many informed and enthusiastic members here to help out. Love this thread.

I just filled a stem as I usually would (filled joint, capped with basket screen) and ran it through 3 entire Cruise sessions, each 240 seconds at 240 C (464 F) without drawing. Here is the herb next to a "fresh" pile of the same strain. I tried not to get any shadows but I'm no photographer.. the piles look indistinguishable in front of me.

That's impressive @Prolusio

I know that the question is for funky junky. But when it's set to cruise the tubo is no longer "on demand". It heats at the set temperature for however long cruise is set for. My cruise is set for 90 seconds so for that time it heats the herb whether I'm pushing the button and inhaling or not. Which seems to be different from what others have posted. I'm usually wrong compared to the experts but my tubo gets pretty hot on cruise and the herb gets toasty.

 

[Shit Snacks]

Even Milaana Mist and Zion benefit from heat soaking as well, makes the heaters more resilient to a faster draw, why you need to hold the buttons less during a hit the more hits you take back to back, natural temp stepping. Here we have a lot of glass, which can rob heat, at low temps in particular (that's part of why Zion heaters switched to mica instead). So on demand works just as fine (still what I use mostly) but may need some preheat at lower temps in my experience, cruise mode makes heat soaking automatic with always on, so true that it is actually even more like a log like this.

 

[Zow237]

None of the vapes with the in demand have cruise mode. So while you can get native rips with fire mode... but heat soaking is where it's at
Anyone know where I can get something like the cork and whip for my bubbler?

 

[rozroz]

if the right herb pile is the "after" herb, it does look a bit brownish/ less green imo,
but if it's the left one i'm totally mistaken

He doesnt take hits,while test is done. It is aimed at showing that tubo doesnt heat much your herb when you are not hitting it.
If you want to avoid this you can just connect the tubo to the bowl only when taking a hit.
For instance I can put a bud just sitting on top of my log vape,it will get brown from the conduction,but That doesnt make it a conduction vape. You are getting some browning in this test cause the herb gets locked into tight space along with the heater for 12 minutes at high temp... This is very extreme case, i never leave the herb inside the tubo for longer than few seconds without drawing. After one draw the bowl will get way hotter and the heat radiated from the heater when not drawing with be negligible compared to that.

Didn't you get a whip with your tubo? Both come from funky junky. I bought the portable stem set from Ddave. One end fits into the whip and the other works well in a bubbler.

yes I got a whip but need a cork for my glass symphony that will be coming this week. need something to get my face farther from the heater

You're correct! The right pile is the one that was in the stem. But I honestly feel any visual difference is mostly from my lighting. My primary light source is above me on the left (you can see on the wooden table that the left side shines much more). Also I held my phone in my right hand for the shot so that might have made that side appear darker.

All I can say is in person there was no noticeable difference to me and I vaped both piles with equally fantastic results . If that's all the "cooking" that's being done when my herb is left idle, for far longer than I would ever want it to be typically, I am very pleased with the Tubo's convection performance! Or I guess it's more lack of conduction? Whatever, I Tubo.

 

[funkyjunky]

Can I ask the status of the box I think/thought I ordered? I am still due 1 long bent stem.

I would appreciate it if I could kind of get a "view" of what else you have to sell / try so I don't spend postage on 3 or more orders, just the two (1 waiting for box), I already received.

THANKS

right, boxes. good thing you reminded me, i went to the cutter today and have them cut. should not be long until they are finished. of course i remember but please also remind me if you think something fell through the cracks

a view is difficult, i think from one of my last posts and "updates" you can get kind of an idea on what i am working on. if you are interested in anything you see on pictures or so, you can always contact me directly. i can also put names on lists that i would contact once i take orders for something certainly helps my motivation.

I'm usually wrong compared to the experts but my tubo gets pretty hot on cruise and the herb gets toasty.

i think i can set this straight and answer @sickmanfrauds question at once:
the tubo does not heat the herbs directly, it heats only the heating element. as said, three thick borosilicate glass tubes with stainless steel coils inside.
only when air is drawn through these three glass tubes, heat is transfered to the material in the bowl, by convection.

the difference in on demand mode vs cruise mode is indeed that tubo just presses the button for you the whole time.

when the heater is cold it will need more power (watts) to heat up the air flowing through because it also needs to heat the tubes.

thanks to others for already explaining this.
@vapen00b 's and also @Prolusio 's tests show that at a minimal distance temperatures are quite low compared to right at the heater screen or even inside the tubes. too low for proper evaporation. if you want to maximize "pure convection" pack the herb as far away from the heater screen as possible. i havent noticed any less or more convection with packing method.

Thanks to all who answered my last question.

Anyone who has used an Extreme Q (from Arizer) knows there is putting the herb in the cyclone bowl or elbow packing (packing the 18 mm joint).

For Elbow packing I have seen it suggested to raise the temperature.

Question: Is there a noticeable temperature difference between putting your herbs in the basket screen or further into the glass with the basket being to cap the load?

Also, is there any easy way to temperature step with the Tubo?

There is a notice-able difference when using the cap,mainly due to the short distance from the heater,and its mesh size being very tiny and the metal rim. I think there is some conduction involved (like in the EVO's bullets)cause it retains a lot of heat,glass bowl gets less hotter than it. I am currently getting best results with large mesh size screen formed like those DDave offers (rimless screens).They make a huge difference ,cause due to their larger holes they retain less heat which allows purer convection.
Temp stepping with the tubo is easy, just press the + - buttons you can either step up +1 or +5,it also interrupts cruise mod but it is no biggie,just press 2-3 times and its on again .

I can only go up by tens... on the temps. How do I change this?

Asked the same thing few pages back and FJ replied ,so i am passing on the knowledge ..
Menu>Interface 1C5F On . This thread is already getting big,i think a Best Of Tubo thread is in order ) !

Ha just over 40 pages is big?

Well Tubo gets you so stoned ,that going trough 40 pages seems to be an obstacle for everyone cause they keep asking the same questions again and again ... Also people spamming how happy they are after every essential post doesnt make it easier to find info.. not that it is not all available on FJ's site... tubo.lamart.ch

lol spamming with happiness. Yeah that's every thread somehow even when shorter than this, people always gonna be asking the same things. Best Ofs only happen when people put in the work, and as demonstrated above, we're pretty lazy... Wonder why?

 

[little maggie]

Ha just over 40 pages is big?

Exactly. Another thread is 36 pages for a vape that's not even ready yet.

 

[sickmanfraud]

Are you guys kidding?

There is another "upcoming and unreleased ..." that has a thread that is 273 pages!!!

 

[Abysmal Vapor]

I see that most of you find my statement funny,but i am not going to teach you statistics. There are numerous threads with 1-10 pages ,havent done the math but i guess the 100 + pages threads are about 10% of all treads... So me saying that this thread is getting big... (40 pages 1000+ posts) is not that much of an overstatement.. even though what i originally meant to say was that there is a lot of useful info scattered around the thread which would be nice if gets condensed..
And those comparison with big "upcoming and unreleased ..." threads is pointless,cause datawise there is very little useful user data there.. only glipmses of what eventually might hit the market ... Now i kind of started wondering which is the biggest thread on the forum which started straight with introduction of a ready made product.. and didnt get 100 pages of pre-hype posts ?

 

[Zow237]

I can only get only One to 2 sessions out of my battery. Also the unit gets to hot use after just one stem

 

[Abysmal Vapor]

What brand/model batteries are you using ? Do you have only one,things got much better for me when a got a second one?And do you load directly into the bowl or the cap ?
The stock samsung 30q was bitchin at the beginning giving me the same performance as you describe,but later it came around 3 bowl session and 4-5 cap session. I am getting best results with Sony VTC 5A 35A 2600 MAH and VTC6 30A 3000 Mah
