We get asked often on what is the best sub-ohm tank to use with Farm to Vape when using a concentrate such as wax or shatter. We have put several head to head against each other to determine the best one. We are judging on leaking, coil flooding (popping), taste and cloud production. We found with all tanks, its best not to fill them up all the way as the constant heating up and cooling down starts to decarb the concentrate in the mix, turning the mix a darker color from its original honey color. Now on to the tests..
The Aspire Nautilus Mini tank came in last in our tests for vaping a wax based e juice. This was the first tank that we owned, not quite a sub-ohm, but felt it qualified to be in the results. It comes with a 2ml capacity tank and is good for mouth to lung hits. It is too restricted for direct lung hits. It uses a 1.5 ohm coil that didn't produce large clouds. This tank leaks, be forewarned. This tank is 2014 technology so lets move on.
The Aspire Atlantis 2 was an instant hit when we purchased them in bulk in early 2016. These tanks have a 3ml capacity and come with 0.3, 0.5 or 1 ohm Kanthal heating coil. These are the only coils made by Aspire for the Atlantis 2 tank. We found the Atlantis 2 gave great direct lung hits from the get go with 0.5 and 1 ohm coils. We thought the 0.3 ohm coils were too harsh tasting. Then within a few hours, the tank would leak out its contents in an expensive sticky mess. There is an aftermarket Ni (Nickel) coil for the Aspire Atlantis 2 that allows temp control in the Atlantis, we have not tried it yet. We will get to temp control in the next tanks below.
The Joyetech Cubis Pro comes with the eVic VTwo Mini started kit. The eVic has a temp control setting for three different types of coils; Ni for nickel, Ti for titanium, and SS316 for stainless steel 316 grade coils. These coils all have pretty linear temperature coefficients so the firmware in the eVic can determine max temp regulation cut off points. This setting is great with the leak-proof Cubis Pro tank using Farm to Vape. We found that ordering the 0.6 ohm SS316 coil was the best regulated at around 420F. The Cubis Pro gave ok direct lung hits and good mouth to lung hits. This set up did occasionally have coil flooding. Coil flooding happens when the viscosity of the mix is not what the tank is designed for. The vape juice flows through the cotton on its own with the draw of air pushing it through. This was prevalent on the Cubis and Cubis Pro tanks. We recommend a new atomizer for about every 1-2 ml of vape consumed. We also have Ti and Ni coils.
The winner of the group is the UWell Crown 3 using the 0.5ohm SS316 coil. With this set up, we were able to utilize the temp control just like the Cubis. This one gave perfect direct lung hits, 10 out of 10. The taste produced was phenomenal. Tastes just like the concentrate at a 1:3 ratio. You have to close the bottom of the tank TIGHT; it doesn't leak! The hits are out of this world with the UWell Crown 3 using concentrate mixed with Farm to Vape.
New tanks and batteries seem to hit the market weekly. For now, we're more than happy with the UWell Crown 3. Looking forward to trying more tanks in the future.
