Discontinued The Grasshopper

[vapen00b]

I tried to do the best thing with a wrap , bought it from an electrical shop , cut it , heat with hairdryer and the work was perfect ! I was very proud of myself until I tried to put the battery in the Grasshopper ... no way , it was too thick ! It's incredible to say , because the wrap was very very thin and all in one with the battery , I did'nt believe. So I tryed another time with a "simple" electrical tape , but a 50 mm. one ( 5 cm ). Done a very good bricolage work, cut exactly the diameter and put it on the batteries. Also this has been a very good professional looking at the end , and it works , it works great and i think there's no way to get a short. The electrical tape is also "flexible" , more than the original . I usually charge batteries on an Xtar VC4 , and when you take them out , if you don't pay attention , you can demage batteries ( I did so with all mine). Sorry if I don't post photo , I don't want to get risks , here where I live people are strange...

Thanks mate. Do you think you could provide a link to that particular electrical tape?

Damn.. I'm not the only one... I too have the VC4. And I guess I experienced the same like you. When trying to get the batt out it spun and got flipped out... The charger is great - but the springs are pretty strong... So be careful whenever you try to get your GH batts out. They're tiny and not too good to grab.


Thanks for your help!

EDIT: OMG have any of you read the comments on the GH on the vape critic's site? lol[/QUOTE]

I have watched his hopper review and read the comments on the vid and his site. It made me realize what a donk the vapecritic is.. He's just shook because he's not able to get any supply to sell and he knows it's the best vape in the game. He doesn't even attempt to use it without water in the video to display it's awesomo powah. He just claims it's too hot for his pretty lips. All other vapes get a visual display.. Same thing with Toronto vape's "review" of the hopper, those clowns didn't even get a unit to review.. Unfortunately all of the vape "reviewers" are pretty craptastic and offer little to no review of the products. It's more of a demonstration and then a link to buy.. thanks for nottin.

It's a big game to the retailers and they wanna push chinese shills-nit all over you. They don't actually care about which vape is the best, they just want the largest markup possible on the products they sell to you. And that's why we have this wonderful forum to decipher all their shills-nit and bring the power back to the people who care

Just found this condensed version of a guide to the GrassHopper!

Lots of good info!

Thanks @lazylathe for the link, but we are ALL still waiting for your GH experiences from last night

Noticed that it states that the GH is 100% convection. How is that possible when I see vapour come out of the intake holes just before it turns blue?

 

[invertedisdead]

I would like to use pure concentrates too , but I think you must charge it every time , or every two. With e-liquid you can stay out for two weeks without doing anything...I got the Joyetech dual , and in dual mode also the two batteries lasts two weeks ( 14/16 hits pro day ). If it would be legal also where I live , I'd prefer my GH in my pocket , with some flowers and two or three batteries and that would be the best. Anyway e-liquid is very confortable.

Nah, I haven't charged it since last Friday and I have pretty much the tiniest mod on the market. Also keep in mind you'll need more hits than me because your concentrate is weaker (diluted with e juice), so you probably use as much, if not more battery power that way.

yeah 100% convection is a strange claim.
On demand heating is as confusing though, for the same reason.

There'd be a tiny amount of conduction, but it would be a lower temp than the air, but a faster transfer.

You must have some dank to be noticing that though..!

I think there's always going to be some conduction in convection vaporizers where the herb sits.

All my medicine is dank...mostly nearing 30% THC. I notice that about a second before it goes blue, I see a small wisp of vapour exist the intake holes. I have personally always felt that the GH was not 100% convection, just based on its behaviour and the resultant ABV. If you want true convection, the MiniVAP is waaay more of a convective experience. I think the GH has a shit tonne of radiant heating, especially once it gets going, which can make the ABV look darker than a true convection vape like the MV. But I could be wrong, and probably am, but this is what I like to believe

I think there's always going to be some conduction in convection vaporizers where the herb sits.

Depends on the vape. The herb can sit in a MiniVAP all day long and not see any conduction.

Air moving through the chamber path, this is much more noticeable with the new WPA. When you insert it into your glass piece there's a little poof of vapour. From my testing, I'm seeing zero conduction happening. The effects definitely provide the purest convection feeling i've come across as well. The material doesn't burn off if you let it sit in the chamber and turn it on. If anything there could be a minute amount of heat conduction passing through the material itself once it gets clumped up towards the front end near the end of the bowl when rippin er hard but who knows. I'll accept the 100% convection claims.

He just claims it's too hot for his pretty lips.

Lol, when my son and I watched that review way back we had a good laugh, came up with a nick name for rhe Critic.... Pussy lips.
And to this day that is how we refer to him.

The hopper is 100% convection. If someone is seeing vapor without taking a draw there would be a few possible reasons.

1. Extremely oily product (and i mean extreme, if you don't KNOW your product is super oily then it's not) it's possible for that oil to smokder

2. Somehow material is contacting the heater, either poking through the screen or particulate has fallen through the screen. It could be as simply as some keif making its way and it should boil off no problem. Let me guess the vapor you see is only on the first hut and subsequent hits you don't see vapor without drawing.

How do I know becaus I was at HL yesterday testing hoppers and designs and I did see on a few units some smoldering, each of those units did NOT have a screen, regardless the variation in temperature or heater design.

Unless you don't have a screen the most likely reason for smoldering is material has found a way to contact the heater.

Otherwise a properly functioning hopper with a screen, you can put fresh greens in a hopper click it on and let it sit, it will not even have enough conduction effect to vape at all without a draw.

There is a difference between smoldering and conduction effect. If you have smoldering it's either the material or material touching the heater.

If you have conduction you have a problem, and need warranty, that is indicative of a runaway heater.

loving my grasshopper. the only limitation seems to be my lung capacity. I didn't realize how much I enjoyed the removable ovens in the Haze vaporizer until I started filling and emptying the grasshopper. I kinda wish the grasshopper had this feature It would both be easier to fill (no funnel required) and would make keeping the gh clean a lot easier. I wonder how many warranty claims are a direct result from users attempting to clean that interior screen?

Seriously? My 3 RMA GH's are "in testing"! What's taking so damn long? Kidding obviously...kinda.

Thanks for the great explanation on the convection properties....could very well be kif because my grind has a bunch of it and i'm quite carefree about it.

Whatever the voodoo may be, there is a big difference between a convection vape like the GH, and the MiniVap....huge difference....same with something like the vriptech heat wand. I think radiation takes over huge once the hit gets going, and same with conduction from the bowl. This isn't so much the case with some other convection vapes.

 

[guyonthecouch]

shout out to @biohacker, been using the term "dirty duction" for the past couple weeks
such a dirty vapour.. only for sundaze

Agree about the MiniVAP ... the Teflon core makes a huge difference vs. SS from a matter of staying cool and preventing conduction ...

Nothing wrong with conduction vapes, they just aren't my cup of tea anymore, same with hybrids like the s&b portables, I just detect nasty flavour profiles even on the first hit at my preferred vaping temps that's all. I'm getting pickier and pickier with time...

Agree about the MiniVAP ... the Teflon core makes a huge difference vs. SS from a matter of staying cool and preventing conduction ...

Especially when using the flexicone modules and not even having direct contact with the bowl. That's what true convection means to me....hot air over biomass.... the herborizer would be another great example.

Nice work GrandWazoo, good job keeping the cell alive

If you have conduction you have a problem

100% convection heater, but if the chamber is at equilibrium with the heater (as would be ideal for the hopper) there is faster transfer of energy from the side walls to the herb than there is from the air to the herb. This effects the profile of the vape.

It's very similar to the Arizer EQ in this regard, which is an adaptable hybrid device that heavily tends towards convection.
Again the heat source is 100% convection oriented, but residual heat is a reality and everyone knows this from the flavour.
I would say the same for the GH.

Did you sign a nin-disclosure agreement??
(I want more insider tester info)

What I really want is a GH WPA though, keeen

there is a big difference between a convection vape like the GH, and the MiniVap

Yeah, different systems different emmisions. An elevated and insulated chamber that is solely heated by air is 100% convection, there is no way the GH is all convection in dynamic.
The walls might not be as hot as the air that is also heating them with convection, but the transfer rate would be hugely better and that is solely conduction.

It's not a snob race though, it's about quickly heating up a herb sample, and the conduction in this instance helps it and is only the most minor aspect of the signature (heaps better flavour than the EQ, heaps)

Hi guys,

I had a mishap and managed to damage to batt wrap a bit (a scratch nearby positive terminal.. The external chargers contact snapped and kinda cut into it... Fuck). Knowing it's dangerous as fuck to use it, I put it away for now unless I find some fitting shrink wrap to rewrap it. Has anyone found a suitable product? Only finding 18650 ones.... Any help is greatly appreciated! (Buying new batts is NOT a fix for my prob, so please don't suggest that )

Thanks for your tips!

i just came across this post and wanted to ask you guys ,

ok so when i got my grasshopper one of the two batteries i got had a tiny bit of the wrap scraped a bit . i didnt think nothing of it i dont know too much about batteries , and have been using it anyways . should i get rid of it and get a new one is this dangerous ? i would post a pic but cant right now the spot were its scraped is about halfway on the battery body it like scraped up a bit and the silver battery is exposed ?

Grasshopper testing night ONE!

Charged up the batteries and loaded some Shark's breath into the GH.
Used my GR8TR with a fine plate since i only own the one plate...LOL!
Set the GH on 5 and hit the button, few seconds to BLUE!!
WOW this thing is FAST.... Faster than the Herbalizer!!
First hit was whispy but tasted great!!
Second hit was out of this world with vapor production!! I had to click off before the load was done and even then, i could not clear the GH or the WT!!
That second hot tasted kind of burnt towards the end and the ABV had some very dark specs in it.

There is a slight learning curve with this vape in regards to grind and how hard you should draw.
Still figuring out the draw... This vape packs a punch and makes testing hard...LMAO!!

All in all i had 3 bowls last night in the GH and that was enough! The 2nd and 3rd bowls were not fully packed either.
I tried temps from 3.5 all the way up to 5 and have not found my ideal setting yet.
5 is like the kamikaze setting!! You better have huge lungs to clear the bowl!

Now to the important stuff for me!
Flavor!! This vape is a flavor beast!! It is like my RooR Vapor in regards to flavor and then like my Sublimator with regards to clouds and density!
Easy to pack and unload and so far the threads seem to be nice and clean!
I wipe out the bowl after every bowl with a q-tip and then blow out the nosecone and give it a wipe as well.

One thing i absolutely hate is exchangeable batteries in a vape!!
My Milaana did not last too long because of this issue as well...
Will see how i do with the GH over time but i am assuming i will keep it due to it's raw power!!!
I am also loving the NO HOTSPOTS in the load!!! Nice and even ABV!

There was a lot of talk about using external charges that are damaging batteries.
This is what i have been doing:
I have the Nitecore D4 charger and set it to LOW when i add the GH batteries.
The charger screen says they are at 4.20V when complete.
I then place the batteries one at a time in the Hopper and complete the charge using the magnetic charger. The batteries charge for a few minutes more with blinking RED and the i get the blinking BLUE light. So it seems that the D4 actually undercharges a bit and the GH charger tops them off nicely.

Will be testing again later today and will see how the batteries are liking this charging method.
So far so good with the GH!

So nice to see you bro, welcome to the party! I used to use q-tips as well, but found too many cotton strands sticking to the inside of the bowl, qtip brand anyway.... but precision qtips apparently work well. I just use a tiny piece of cotton cloth now.

Great idea! I wonder if that few mins extra charge on the oem usb will just give it that little bit of extra oomph? Or perhaps prevent my 2nd click syndrome...hmmm....more testing!!!!

Give your SCS 3 piece a whirl....see how it stacks up to the super fine grind of the gr8tr fine plate! I think you'll get even better flavour!

wrt to battery charging current, nice article here:
http://batteryuniversity.com/learn/article/charging_lithium_ion_batteries

The advised charge rate of an Energy Cell is between 0.5C and 1C; the complete charge time is about 2–3 hours. Manufacturers of these cells recommend charging at 0.8C or less to prolong battery life. Most Power Cells can take a higher charger. Charge efficiency is about 99 percent and the cell remains cool during charge.

C = mAh of the battery

100% convection heater, but if the chamber is at equilibrium with the heater (as would be ideal for the hopper) there is faster transfer of energy from the side walls to the herb than there is from the air to the herb. This effects the profile of the vape.

I couldn't agree more. You have to take into account the chamber design and material which can introduce small amounts of conduction. If you just turn on the Grasshopper and let it sit, it won't cook your material. However, once you start to take the first hit the chamber walls heat up which adds a small amount of conduction to the process. Taking one hit at a time will lessen this effect but it is still there. Taking multiple hits in a row will increase this effect and allow for a little more extraction from your material.

There is also radiant heat to consider. This is mostly affected by the distance from the heater to the chamber.

Most vapes that are 100% convection in theory are probably more like 90-95% convection. A log vape, for example, has the material very close to the heater introducing more radiant heat, and the stems are glass, which provide some conduction, or stainless steel which provides extra conduction and slightly bigger hits. Even the Evo will cook an ELB if you leave it in the bamboo for a while.

Being less than 100% convection isn't a bad thing, it gives vapes their unique signature and effects profile. My Sticky Brick vapes are the purest convection I've experienced. The chamber is made of wood which conducts almost no heat to your material. The heat source, which is the butane flame, is also far away from the chamber and above it, introducing little radiant heat.

Hawk found this a while ago and these wraps seem to be the right size. Youtube has videos showing how to use it. https://www.amazon.ca/Long-17mm-Shr...19020&sr=1-16&keywords=pvc+heat+shrink+tubing
