a couple of questions about attys and curious about bottom feeders

[morbid4joint20]

Exactly how does a bottom feed work and does it use a regular atomizer. Plus im getting an18650 setup of some kind with a low resistance atty. any suggestions on what type as far as thread size or differences. is there a good site for learning all about attys?

First, I want to make sure I understand right. You're getting a bottomfeeder which takes an 18650, and includes a LR atty, right? If so, read on. Otherwise, please clarify.

Your atty choices are limited by what's on the mod. I can't say for certain because everyone's different, but 510 seems to be the typical atty of choice anymore. I know it's also what's on my bottomfeeder. With 510 threading, you can use an atty or carto with resistances from about 1.5 ohm to 3 ohm (or even higher for high voltage mods). Obviously, the lower the ohms, the lower the resistance. Lower resistance means it gets hotter, faster. It produces more vapor, which may seem to lose a little flavor. That's the traditional trade-off; the more vapor, the less flavor. However, a lot of experienced vapors will not use regular resistance on a 3.7v mod (which is what the 18650 battery is, btw). The loss of flavor is minimal compared to the increase in vapor production and throat hit. Of course, each person has different tastes.

I can't speak about any atties outside the 510 threading because I don't use them, but any 510 or 306 atty or carto should work on your mod. The resistance is up to you and will probably change as you vape more, until you find your sweet spot.

Hope that helps. And I'm sure someone will be along shortly to correct any misinformation.

yep, Boris is right....
also, a bottom feeder does just that: the juice is squeezed up from the bottom to the bottom of the atty.... most attys can handle this. 510 - 306 both fit on the 510 native connector which most use everywhere. 901 or 801 attys require an adapter to the connector.

beware of overtightening any atty... the center post is vulnerable to movement and can shut the atty down. kaput ... until fixed if poss.

Yes indeed. I made this mistake with the first mod I made. Had problems with the center post of the battery connector and forced the atty on there. That was dumb.

More details on bottomfeeder - generally, it's just a bottle with an injection post (i.e. syringe) that goes up through the bottom of the atty. A little squeeze on the bottle (or push of a button, etc) feeds juice onto the atty. The amount of juice per squeeze can vary. A little practice with it and you'll forget that you didn't know how.

BTW, a bottomfeeder as your first PV is a little unusual (but not unheard of), but I personally recommend it to some because of the level of convenience. Most people start with something that looks more like a cig and have to carry spare batteries, carts, a charger, and/or some other gear. A bottomfeeder with an 18650 should last through the day and night for almost anyone.

also, a bottom feeder can get over fed, and flood the atty....

learning to drip is essential to knowing how to best use any type of feed system... main points: not too much, not too little (depending on the atty).

best formula: 2 to 3 drops from a standard juice bottle... no more no less.

 

[BorisTheSpider]

3 drops tends to be the average. You'll see the odd person say either 2 or 4, but 3 is pretty normal. When using my bottomfeeder, I squeeze *just* until the juice starts to come out the air holes at the bottom of the atty. I immediately take a decent draw to immediately use up any excess there may be, but that tends to be right on the money. That's one of the nice things about using a carto on a bottomfeeder - you have a little room for error because the filling will soak up the excess. However, to me at least, using a carto on a bottomfeeder is self-defeating. A bottomfeeder is supposed to emulate the dripping experience and a carto prevents that.

There are also two types of bottom feeders. The easiest wat to tell them apart is to look at the bottle. You might have the feed tube going to the bottom of the bottle in which case you would hold your mod with the atty up and squeeze until you start to see juice at the base of the atty. The other type is commonly called a tip and drip. This model has the end ot the feed tube at the top of the bottle. To feed an atty on this model you need to tip the mod over then squeeze the bottle. Bottom feeders really do rock!! Enjoy your new mod.

i have been a stickler for my vaping experience: to me, bottom feeding is the opposite of dripping... which is literally "top" feeding.
I have given up bottom feeders pretty much, except for my "tip and drip" or "gravity" fed bottom feeder....and until a new auto drip system pv hits the market, and how that pans out (there is one coming out soon) top feed devices are pretty non existent..

I think dripping, just the right amount, on top of the wick, or top of the coil area, is the ultimate vape.
