I got all my DIY stuff from BlueMist vapor. They have everything youll need and I only spend about $70.
Youll need unflavored nic juice.
Bottle of PG
Bottle of VG
bottles of flavors
Then its also good to have a few different size syringes and some pipettes for measuring. Some people just use dropper bottles but syringes are much more accurate. And thats important, especially with nic juice.
Nic juice is NO JOKE so make sure your very careful. It will absorb through your skin if you get it on you and it can make you feel like crap If your buying a high mg/ml nicotine and cutting it down I really suggest using a syringe. Its very important to be accurate with nicotine.
Make sure you read the DIY stickies and ask any questions you have. DIY is fun, but can be dangerous if you dont know what your doing.
I got a 120ml bottle of 60mg/ml but they also sell 100mg/ml and 36mg/ml, and in 60ml ,120ml, and I think 240ml bottle. I got it in a PG base bc I make juices around 70%90%-PG.
You can get 120ml bottles of PG and VG for $4 each. Thats one of the cheaper prices Ive found for PG and VG.
Then buy a bunch of 3ml DIY flavors that youd like.
There are many other vendors that sell DIY stuff and flavors too. I just found BlueMist was very affordable to get the stuff you need to get started. Then buy flavors from the many different places. Like others said, thats where it can get expensive.
Also you will need to get some empty dropper bottles to mix in. I would get the smaller ones to start. DOnt make bigger batches unless youve already made the juice and know you like it. I would get either the 3ml or 6ml empty bottles.
Also then you need to download a juice calculator. I use the E-Juice Me Up calculator and it works very well. You can download it for free.
Make sure you double check all the inputs and take notes. You will put in everything on the calculator and it will tell you how many ml of each part are needed to make the juice. You put in the mg/ml your nic juice is, then what mg/ml you want the DIY juice to be at, as well as how many ml the final product will be. Youll also put in what PG/VG ratio you want it to be and what % of flavorings you want. It will then show you each part to make the juice, and exactly how much of each. It makes it very easy.
That would give you the basic essentials to get you going. You can also get sweeteners, menthol drops, menthol crystals, liquid that makes juice feel cool on the exhale, etc but all that stuff isnt nessesary. Some of the stuff can make juices better or give it alittle kick, but they have to be used in the correct amounts or they can make juices much worse.
Also make sure the flavorings you get are not oil based. You want to get water soluble flavorings. Also most flavorings are mostly PG but not all. So make sure you find that out. Some flavors are not PG or VG based. BlueMists flavors are not PG or VG based. The calculator will allow you to put what the base of each flavor is or if its neither PG or VG. That is important bc that will affect how much PG and VG need to be added to get your desired PG/VG ratio
Sorry this is kind of all over the place. I kept thinking of different things to add ,but i hope it helps.
Goodluck!
