just make your own liquids, buy the base ingredients, nicotine and flavours
once all the ingredients are well mixed, you can use the juice practically straight away (few hours) - all that waiting for days for it to steep went out with the ark
Yesterday I bought 500ml of PG, 500ml of VG and these were £5 each - this is a litre for £10
I got 60ml of Nicotine for a tenner and I already have the flavour, 30ml which was £8 online
I only have enough of the flavour to make 300ml, this is my recipe from an online calculator:
257ml of the PG/VG mix
12.5ml of the nicotine as i want it to be 3% - or 3mg as it's commonly labelled
30ml flavour
METHOD:
put all ingredients (measured, not guessed!) into a plastic jug, place the jug into a large saucepan and pour hot water into the saucepan, this thins the ingredients down so that they mix easier.
once warmed (don't try to cut corners and microwave or you'll lose nicotine and impair the flavour) mix well with an electric blender/hand whisk.
leave the jug in a dark place, covered with newspaper or a cloth. a few hours later you can bottle the liquid, refrigerate the bottles for 2 hours, then it's ready for use.
300ml cost:
257ml pg/vg = £2.57p
12.5ml Nic = £2
30ml flavour = £8
Total - £12.57 for 300ml
please note that you are currently paying £120 for 300ml
