There are a few tips and tricks that are necessary when wicking the Avocado 24. First of all, I have every different type of Avocado ever made, and I have a love affair with each of them. Each has their pros and cons, but all of them are amazing atomizers, and to this day remain my favorite all day banger tank. I have TONS of experience with each one, and have tried any and every wicking method, an insane variety and number of builds, and have vaped gallons of juice through them all, especially the 22 and 24.
Ok, so when it comes to the wicking, obviously the amount of wick you have wil vary depending on the ID of the coil. However, the size of the actual wick tail ging down into the tank MUST remain a constant, no matter what size ID you are using. You can even trim the tails at an angle, so the end of the tails have a point to them almost. I do this with any ID of 3.5mm, but found it not completely necessary as long as you follow the following techniques I outline. This tail "thinning" will be even more important the larger the ID. So, the tail lengths of the wicks should be long enough so they protrude about 3or4mm beneath the deck. So in other words, while looking at the filled tank from the side, you should only see 3or4mm of wick tail hanging down into the glass. It is completely unecessary and counterproductive to make them any longer than this. Simply tilt the device toward your face while vaping, with the coil and wicks facing you, and it will wick nonstop as you tilt and vape it. Secondly, after you pull the wick through the coil, thin out each tail using metal tweezers, by simply "combing" the wicks out, starting at the end closest to the last wrap of the coil, and out toward the end of the wick tail. Do this a few times, thinning the wick, and at the same time, fluffing it up a bit. Lastly (and most IMPORTANTLY), after juicing up the wicks, and filling the tank, use something small, like a 1mm screwdriver, or a thick gauge piece of wire, a paperclip, whatever, anything that shape and thickness....lol....and use it to push the wick sitting in the wick hole to the side a bit, making an ever so slight gap, allowing air to travel to and from the tank. This small gap between the entire wick and the side wall of the wick hole GREATLY improves wicking capability, allowing air to travel freely, preventing any sort of air lock or vacuum effect within the tank. (This last technique should be used on ANY RDTA you vape on, trust me).
Welp, I am sure if you follow these tips, you will have nothing but a delightful experience with the Avocado 24. It is a truly stellar piece, ENJOY! As always, Keep Cool and Vape On! CHEERS!
