By now, we all know that dreaded feeling – going to hit your vape and tasting nothing but the flames of hell, no flavour and a throat hit that is full of nothing but pain to go along with a nicely ruined coil – this is a dry hit vape!
Thankfully, these issues can be avoided reasonably easily!
What is a Dry Hit When Vaping?
Dry hits are when the cotton (or other wicking material) in your vape is not saturated with ejuice. This can either be down to a wicking issue, a coil being ran at too high of a wattage (or in need of being changed) or simply having an empty tank!
How to Fix Dry Hits in Sub Ohm Tanks:
1 – Does your vape tank have juice in it?
It may sound a little silly, but there are plenty of times the staff at Vapour Depot have been working on packing orders, on a live chat with a customer or just chatting and didn?t realise that their tank was running dry! Most tanks have a minimum juice line – after your ejuice has reached below this, your coil will simply not have a way to get any more juice. If your tank doesn’t have a minimum indicator, then make sure to refill your vape once the juice level reaches the bottom of the cotton on the coil head.
2 – Are you running your vape tank the right wattage?
Almost all replacement coils have a recommended wattage range on the side of them.
This is specified by the manufacturer so you can be sure you are getting the best performance from your sub ohm tank. If you are running your sub ohm vape tank above this wattage, then you are risking running into wicking issues where the coil simply can?t keep up with the amount of ejuice required to keep your wicking material wet – leading to a hit that resembles a desert rather than the flavour you are expecting.
3 – When was your coil head last changed?
Replacing your vape coil at regular intervals helps more than you would think!
Over time, certain things in your e juice (such as sucralose sweetener) can cause a build up on your vape coil and start to reduce the effectiveness of your wicking materials which also slows how quick e liquid can reach your coil. If you have been using the same sub ohm vape coil for an extended period of time, you may find that you are starting to see a reduction in flavour and your vape is starting to taste a little ?unsaturated?. This is probably a great time to look at replacing your tanks coil head!
4 – Is your ejuice ratio correct?
Some vape tanks have issues with some juice ratios, based on the size of their wicking ports (the little white cutouts on the side of the coils – thats your wicking material). If you have small wicking ports on a coil, it would be best to use an ejuice that is lower in VG – a 50VG 50PG juice may be better suited to these types of coils.
How to Fix Dry Hits in Rebuildable Tanks / Drippers:
In rebuildable vape tanks & rebuildable dripping atomisers (such as the Geekvape Zeus X RTA, Hellvape Rebirth RDA or the Oumier Wasp Nano RTA), there are extra things to consider over a Sub Ohm vape tank as the coils have not been built for you.
1 – Are your coils firing correctly?
When you install a new coil (or pair of coils) in a rebuildable atomiser, the first thing that you should do is fire them without any wicking material to make sure they are glowing evenly. Your coils should glow from the inside out without any hot spots (super bright glowing ?marks? on your coils). If they are not, simply give them a little strum with a pair of ceramic tweezers or flathead screwdriver (if you are using a metal tool – make sure not to fire your coils at the same time as this will cause your device to short).
2 – Are your coils shorting on any part of your device?
If you are using a rebuildable tank or a dripper, before installing your wicking material we would always recommend putting the device together (including any chimney sections or top cap) and firing your device. Check your builds resistance before putting your device together then fire it when everything is back in one piece and you shouldn?t see a change in resistance – if you do, it may be that your coils are shorting out against another piece of metal in the device! Make sure your post screws are nice and tight too, as a loose coil can also cause issues further down the line.
3 – When was the last time you re-wicked?
Over time, certain things in your vape juice (such as sucralose sweetener) can cause a build up on your coil and start to reduce the effectiveness of your vape wick which also slows how quick vape juice can reach your coil. If you have been using the same cotton wick for an extended period of time, you may find that you are starting to see a reduction in flavour and your vape is starting to taste a little ?unsaturated?. This is probably a great time to look at replacing your vape wicks! Simply take your RTA vape tank or dripping atomiser apart, remove your wicks, fire your coils after rinsing in warm water and make sure they are glowing evenly! You don?t even have you replace the coils every time – they can go several weeks or even months between changing!
4 – Is your rebuildable atomiser wicking correct?
Now this is a slightly more difficult one, but is your device wicked correctly?
This is less important on RDA drippers as the purpose of the wicking materials is really to hold your vape juice for your coils (which is why you have to re-drip every few hits), but on a rebuildable tank atomiser this is normally the number one cause of dry hits.
When building your device for the first time, have a look at youtube reviewers as they normally have some great tutorials on how to build these devices. If you need a recommendation, try Mike Vapes.
Alternatively, we do offer a full pre-build service when you are purchasing a new rebuildable vape tank or dripper tank where one of our staff will do all the hard work for you so you can be sure your device will be wicking like a champ!
5 – Is your vape mod wattage correct?
This is less important than Sub Ohm tanks, but can still cause issues. Based on your coil resistance, you should be running an appropriate wattage. There are exceptions to this, but you wouldn?t run a higher resistance build at a high wattage (i.e. we wouldn?t recommend running a 0.7 coil at 100 watts) – your coil will overheat and cause your wicking material to burn.
Burning wicking material is exactly what a dry hit is!
6 – Is your vape liquid ratio correct?
On a tank such as the Wake Mod Co Littlefoot MTL, the wicking style is suited to lower VG ratio e juice so you may find if you try and use something 80VG you are going to run into wicking issues after one or two hits.
We know there is a lot of information above and we have tried to keep as short and to the point as possible, but after time you will know exactly how to get the best performance from your tank / dripper and make sure you don?t end up inhaling something worse then you ever imagined.
Here are the three main things to consider:
- Your wattage is correct for the coil you are using
- Your wicking (or coil) isn?t looking like something from a horror movie
- You actually have juice in your tank / dripper
We hope that this dry hit vape guide has helped you to find out how to fix dry hits or at least diagnose any issues you?ve had.
