So last week I bought my first mechanical mod.. an infinite stingray mechanical mod clone and I could never get those big clouds you'd see other people who have mods get. I use an 18 mg nicotine with 50% PG and 50% VG (I also have juice with 100% VG and juice with 0 nicotine but those are 50% VG) and I use the purple efest 18650 3.7V 2500mAh battery. I've fully charged the battery and I still don't know why I can't get big clouds. I didn't try the 0 nicotine juice with it yet, just the 18 mg nicotine 50 vg. Am I doing something wrong to not get big clouds?
