This is one of my mini lab lamps to test wicks. I normally use kerosene to test capillary action.
These are small individual jam jars with metal caps.


The extreme test is to use 100% VG for the fuel. Only three wicks have been successful. 90mm tightly rolled 500 SS mesh, 90mm tightly rolled 635 SS mesh, and the 2mm 12 strand hemp . This video shows the new 2mm from Lovepedal on 100% VG. Past tests with cotton and bamboo all burned the wick in a few seconds. Clic on pic for video.

Let the flame burn for half an hour. The wick shows a little normal charring from the flame. Evod for size comparing. The only ceramic wicks I have tested are the LC2000 in 3/32 and 1/8 size. Neither could maintain a flame with kerosene, much less VG. Have some channeled LC2000 coming but my brain can't get around to how that improves capillary action. I can see it improving gravitational flow when tilting.
This new hemp from Lovepedal is a very good wick, it is pretty large, but it is loosely twisted. When wet it can be twisted tight and will fit a 2mm hole with no restriction on the capillary action. I have rewicked three EVOds with it and they are vaping great. I again recommend washing all wick material with dish detergent before boiling. With hemp, washing with detergent also softens it. When I say wash, I mean working it between your fingers, not just soaking it.

Couldn't even keep the rigid ceramic going with Kerosene? pfft...and I hear you on the channeled version, a boost on the tilt (which I always considered cheating...if I have to pour my juice onto the wick, it's not a wick, it's a stick)...I have to admit the rigid ceramic had me interested but the more I read about it the more I want to just let that bandwagon roll on by...besides, next month some lattice structure grown from carbon nanotube will be the "best wick ever!"

So I'm totally bummed, my hemp got stuck in Bakersfield according to USPS tracking so it'll be next weekend...once I tried my 1st boil of my bamboo with a little Dawn dishsoap in the water, and it did fluff it up a bit more than usual (though it took a couple boils after to get rid of the soap)...do you think that would be equal to a detergent wash BJ?

Quig: Probably your wash does the same. I just wet the hemp under the faucet, pour some detergent on it and rub it with my fingers. A bunch of yellow crap comes out in the suds. Reminds me when I started doing the same with SS mesh, bunch of crap that maybe passive boiling doesn't remove. Boiling can sometimes just cook and sterilize but not remove.

PS. The VG flame test on the mini lamp is a real wick test. No doubts that hemp wicks well and resists burning.

Today I've received the 1mm twine from etnico.co.uk, and the 1.5mm from naturallementchanvre.com!

The British (Chinese) 1mm twine looks absolutely the same as lovepedal's one, 7 strands and similar softness.

The French (Romanian) 1.5mm [2mm at least, to my eye] is very soft, made of 12 strands, and smells of manure to high heaven :?:

After the usual boilings, the test drive: excellent capillarity and flexibility for both of them, but they both still smell of "rope" way longer than the reference lovepedal 1mm.

By the way, here is a collective pic of all the hemp twines I've tested so far:

HempTwines.jpg

Top to bottom:

Rawganique.com 1mm/6
Etnico.co.uk 1mm/7
Lovepedal 1mm/7
Naturellementchanvre.com 1.5mm/12
Rawganique.com 2mm/12

Rawganique's 1mm isn't very good for wicks, in my opinion, while its 2mm sibling would be excellent but still smells of rope (some) after 3 bolings...

Thus the best of the bunch for me is still Lovepedal's 1mm... Etnico's would be more or less the same, yet for some reason its 'rope' smell seems to last longer.

I'm now giving Etnico's 1mm and Naturellementchanvre's 1.5mm yet another pass of boiling, but this time with a few tablespoons of sodium bicarbonate added to the water... it that doesn't kill the rope smell, I'm afraid nothing else will :) We'll see...

Sodium bicarbonate update.

Executive summary: it didn't work.

Bloody details: the 'thermal bath' produced the softer twines I've ever dreamed of, unfortunately their former excellent capillarity now seems to be greatly reduced. No clues as to why, perhaps too much bicarbonate did saturate the fibers?

Next step, boiling with lemon juice. OK, just kidding ;). Hmmm...

what i ment to rewicking kangert3 is removing the silica wick from the stock coils and replacing it with hemp.
so ?mm should i order?
I haven't tried it yet, but I would try 1mm or smaller. The hemp swells when wet with e-liquid. It may take some trial and error experimentation on your part. I hope this helps:)

I find washing it with dish detergent before boiling gets rid of a lot of the breakin flavors.

I don't have any break in flavours at all. First few wicks i didn't even boil. I wonder if the boiling changes the wicking quality though. I've just boiled 20cm of hemp to try out.
My ohms are still not stable. Made a wick yesterday for my dripper at 1.9 ohm . This morning it gives me 5.9 ohm...:-(
Anyone got any pics of their wicks

That's way too much difference IMO... Check if you have any contact points loose, either on the res wire poles or in the atom connector itself; given the huge diff in ohms, I'd look at the atom connector first.

BTW, what mod/atomizer/wire are you using? I've experienced something like that with the A7, initially, for their 'adjustable' positive pin contact is garbage...

I've taken the A7's apart and squeezed where the pos pin screws in with a pair of pliers...takes out the wobble and the sometimes crazy ohms drift.

I'm not familiar with it, does it sport an adjustable positive pin? I would check the contacts with the mod, in my case the A7 was making lousy contact and hence its resistance appeared way higher than it was in reality.

did you test your DRA XL with a multimeter, as well?

Following BJ's example, I've got in touch with Simon at Etnico.co.uk, asking him if he might stock also a 2mm natural twine, similar in specs to the 1mm they already sell (which proven good in my tests).

The owner replied he will try and source thicker wines, he'll advise when available.

Hey, another source for us Europeans: 100% hemp twine & Leather cord,Beads & body jewellery :)

They sell this 1mm twine - also on ebay, handle "etnico", but with slightly higher shipping prices - which would look similar to Lovepedal's 1mm. On paper, that is.. we'll see.

Ordered 1 ball (some 400'/130mt :facepalm:), will let you know how it goes when I get it.
