The G Pen by Grenco Science

[OF]

I used the atmos battery that came with Optimus carts. It works just fine with the 1.5 carts from D9. Is that what you mean?
As far as not all 3.6v supply's not being suitable, can you expand on that thought? Lets assume same thread pattern.

Thanks, good to know.

Threads are not the only issue some times. Nor is current itself, although that seems a factor. My take is a lot depends on the load itself. For instance, both the high power Omicron carts and DART are the same basic resistance, 1.5 Ohms. Many supplies have trouble at that level (hotter than most e-cigs), they show bigger 'voltage sag' under load. This means less heat, of course since the current goes down proportionally and therefore the power drops by the square of the voltage (or current) drop alone. A few tenths of a Volt can make a huge difference, as we see with the big performance jump with Omicron V2 when we dump the 'obviously better' IMR 14650 for the much lower capacity AW IMR 14500s. Of course a simple 'non electronic' supply like the Alpha is improved even more using that same battery. I think due to the 'nested' heaters and ceramic inner furnace Omicron has the advantage as the power drops, vapor production falls off, but doesn't stall out as abruptly as with DART. Put them on a VV head and dial the power up and down and this is pretty easy to see. Underdriving the little heater in Omicron still gets it hot enough to make vapor at a lower rate, but when you need to heat the much larger volume in DART (with higher losses through the walls and through conduction down) you reach a point where you just don't get hot enough any more anywhere in the unit.

This can, of course, also work for you. No less a sage than our own NDA is a big fan of the Ego 'Twist' supply for DART. This is a VV unit, but power limits just past 4.2 Volts so it basically always puts out what a 'hot off the charger' battery would when set to 'full blast' (4.8 Volts IIRC). I like it as well, but prefer the AW IMR and the Alpha Ultra (14500 based) since it doesn't 'go flat without warning' on me. When it gets slow I can always squeeze a few more hits out of the poor little battery if needs be.

Confusing enough?

Confusing, no....interesting, yes.

You have a few points there I would like to pick your brain on then, as I seem to have had similar experiences, and ones contrary to yours. But let's not derail the g-pen thread, as I can see this going off into batteries, carts, atomizers, material used and its influence on the system being used.

Where would be a better place to open this up? Not that kanger thread, or eskillet .... Lets not limit the conversation to one platform.
I guess the goal would be to examine, report, and compare findings of various e-cig equipment in relation to its use as oil vapes, thus helping others (and ourselves) to find the set up that met their goal. With how many post I have read about the subject it seems fitting, yes?

The coming Cera looks promising, but lets face it at 100$ a cart how many carts are you gonna own?
The ecig solution, cheap, disposable, reuseable with care, and still does the job. Not to mention with all the different carts out there a vape user could find his/her right fit, and have various carts with choices on what they feel like vaping.

Or maybe this is to much work, but I am up for it if you are.

The coming Cera looks promising, but lets face it at 100$ a cart how many carts are you gonna own?

I think the answer is "exactly one!"? Cera offers what a year warranty on the heater (and $15 rebuilds after that) and lifetime guarantee on the rest. You just ISO soak and boil them 'nearly as good as new' as often as you want. That's the point. I have maybe 3 dozen Omicron carts in various states (a dozen never used, a dozen trashed awaiting the next tear down session, and a dozen or so in various stages of 'used up'. That's a whole lot more than $100 and they will all be gone before I expect Cera to act up (although I've ordered one spare to keep filled with PG.....). I have several Revolution/DARTs, none have given any trouble, really.

OTOH, Omicron carts seem to foul out (with no way to clear it) very predictably. Both systems have good and bad points.

I think the idea of a 'collected wisdom of the forum' on modified e-cigs as vapes has great promise for some, although it's both hard to pull together as you point out and a moving target. And likely to get filled with strongly held opinions based on fairly narrow perspectives? Perhaps some sort of Vapropedia page?

okay, so I am trying to attach an ego-c twist battery to my gpen glass tank. problem is I have no idea where to buy an adapter to make the 510 threaded ego work with the gpen's threading. does anyone know what threading the gpen uses? also, can anyone please offer some advice on an appropriate place to purchase such an adapter?

 

[whyblameus]

Does the tank have threads that go into the battery aswell as the ones that screw over the battery? Cause im pretty sure the inner threading is a m601. But I dont know of any adapters for the outer threading.

Look back at posts 227 and 228 on page 10 for the answer to the thread number and where to buy the adapter.

i just recently purchased trippy stix trippy chamber TODAY , the chamber is hands down a WONDER i will be strictly using trippy chambers for my full melt vaporizing WORKS AT EXTRMEMLY LOW TEMPS LIKE 3.0V!!!! FITS ALL 510 DEVICES im telling you from someone who looked into the g pen the 710 the everything for wax or dabs and this trippy chamber ontop of any and i mean any 510 device is a BOSS i just got them in so im not sure on how long itll last but you can refill them by just dropping your concentrate in it and it seems very nice. plus they have a number of different styles that i repeat FIT ON ANY 510 DEVICE you do not need theyre super over priced battery or tripppy stix .

My Glass G-Tank with the nail came today. Even while overcoming a bad flu, this thing hits amazingly smooth. And the taste, ahhh~ No more fucking plastic, nothing but my oil's flavor! Thanks for the recommendation guys, it's damn near perfect so far.

I say damn near because the cover/mouthpiece doesn't slide all the way over, almost, but it doesn't snap in place like it does with the plastic wick cartridge. Does anyone else find this to be true or is there a special little trick to it?

 

[Mynameismud]

I just saw they have replacement atomizers now so I Just ordered a MicroG, cant wait to get it. The replacement atomizer looks a lot different then the one my buddy has, the picture shows a screen in it, so I placed an order for it too.

Yup I got one for free when I asked for a replacement when my original broke, it is all metal now in the middle with a screen over the wick

 

[Mynameismud]

Ill find out soon enough but What do you mean by all metal? In the picture it looks like there is no more metal wire around wick and it looks all ceramic with a screen on top. Is that wrong?

And is the screen removeable and does it clog easily?

 

[Ipad]

The metal ring above the coil

The old micro g tank had a thinner metal ring with two holes on the sides and a lower plastic layer wrapping the outer side


The new micro g tank has a thicker wall with no plastic around it

Had my G-Pen for about 4 months now and I'm definitely impressed. First oil specific pen style I've owned and I enjoy how it seemingly prolongs my stash since I'm not dropping massive bomb dabs on my titanium nail. My only problem with the product is that the stock wicking system is irrelevant to the system, forcing true oilers to invest more for the glass tank setup with the funnel. I understand that the wicking system is specifically for the lower viscosity liquids but who's really using it for an e-cig type device? Step it up Grenco, give us them scientific goods stock!

 

[YeeeBuddy]

I'm going on vacation to mammoth mountain CA on the 19th for 4 days, was hoping to have the cera for the trip but I think thats a pipe dream at this point. So i am considering going halves with 1 of my buddies and getting the 2 micro G's for 100 and splitting it. Will this come with everything for 2 people or are we gonna have to get another charger? I know its not gonna last, I dont really care I only need it to work for 4 days anything after that is just messing around till cera comes.

Have any G-pen users vaped Pure gold in this thing or is it too thin?How much do you drip on at a time?

Hello everyone.
I recently bought an original g-pen from a headshop. However, upon removing the mouthpiece, I noticed that the filter was missing. So essentially, there is nothing blocking the airspace between the atomizer and the mouthpiece. Would you guys say it is still safe enough to use?

You should be fine, I took mine out after it got all caked up and impeded my smoking ability by increasing the resistance through the mouthpiece. Puff on brotha

 

[NorSoCal]

Thanks for the quick reply!
Okay I just loaded a bit of lambo budder and took a 5-6 second drag. I checked the cartridge again and the top of the atomizer(?) was empty. Is it supposed to melt that quickly or is it just that the consistency of budder is not optimal for vaping? Or am I placing it wrong? I nestled the budder smack dab in the middle of the two semi-circular cylinders, on top of the central coil. When I hit it, the first drag didn't produce much smoke. However, the second and third hits were pretty thick, BUT when I checked the cartridge after the first drag, there was no budder left whatsoever.
So how would I be able to tell when I stop hitting concentrate and start inhaling plain vapor? Is there a discernible difference in the taste? Or color of smoke? Because I can't tell if i'm inhaling the budder or plastic.

edit:
sorry for all the questions, I just want to make sure I get it right

 

[od88]

Mine didn't come with a filter either, just a metal screen.

It does melt very quickly. If you're using the original G-Tank wick system, most of the first few dabs get absorbed into the wicks, but when the wicks are oiled you'll find that it lasts very long. You can prime it by melting a little on the sides of the wick near the coil, but loading it straight on the coil will eventually do the same.

It can be hard to tell when you've pulled in a strong cloud. What I do when I'm inhaling is puff out a very small amount of vapors through my nose to get an idea of the density. It took a little getting used to, but many coughs later I realize it depends on how fresh the pack is. For me, fresh dabs are generally 3-5 second pulls. Old melted dabs usually require twice that, pressing the button twice for 3-5 seconds in one pull. I also find the battery charge to be a variable as well.

If there's a disconcerting plastic taste, like I had noticed, I highly recommend looking into the Essential Oils G-Tank.

 

[NorSoCal]

I see. However, it's hard for me to know what the taste of plastic is. My wicks are doused with oil so I can't tell if I'm getting nothing or just really old concentrate...
I've been continually taking hits because my wicks are still soaked. Now I'm kind of scared I've just been taking hits of plastic....

 

[od88]

It's hard to say to be honest, and I think that's why a lot of people don't use plastic cartridges. There's a funky smell/taste even before adding any oil, and after feeling how hot the plastic casing gets from heavy use it should certainly raise an eyebrow. Being that your wicks are doused and you're getting heavy hits, I'd say the wick system is doing it's job, just don't let it get too hot or dry.

 

[UpUpandAway]

Anyone own/use both the MicroG and Cloud pen?

Does the metal screen on the heating element of the MicroG make a significant difference in performance (vapor production, taste, efficiency, etc.) vs. the naked heating element of the Cloud pen?

 

[NorSoCal]

Okay I'm pretty sure I'm just smoking plastic now, so I'm going to stop.
Can I smoke the residue from the wicks if I scrape it off with a heated up safety pin or something?

 

[od88]

I had considered doing the same, thought about using isopropyl alcohol, but figured the return would be minimal and decided to have it as a backup instead. I guess you could try, but I wouldn't doubt the taste of the tank will come with it.

I tried. Was gross.
I'm probably just going to buy the new cartridge that comes with the nail, it seems pretty legit. Hopefully I'll get lucky and run into a clinic that actually sells one in the Easy Bay..

Fortunately I just went out and bought a gram of some Blueberry wax.. but idk if this is acceptable..

I thought all good wax was supposed to have a yellowish hue?

edit: Ah, I seemed to have posted the picture in the wrong forum.. my apologies. will repost.

 

[od88]

Looks similar to what I have. Mine was sold to me as honey oil, it's very sticky and stretches at the slightest poke. I store it on parchment paper because it sticks to everything, and have to heat the metal tool so the oil drips on the nail. I've heard different things regarding potency, but have read that amber oil is a good indicator for quality oil. I definitely don't have any complaints, though I haven't tried any yellow waxes yet.

The nail is a great solution. If you're going to get it, be careful not to overload it, otherwise you'll find your precious oil leaking from the bottom of the nail inside the glass tank (not too big of a problem because I was able to reclaim using a needle) or bubbling up to the mouthpiece. Also, it has 2 heating elements with 2 different purposes: Use the top heating element, after dripping your oil on it, to melt the oil down and it will drain to a lower chamber containing the second heating element. It only takes a few short button presses to melt the oil down and you're set. If you can't find it anywhere, I was able to buy it online for $39 with free shipping at buy.com (search: Glass G-Tank).
