charliemen, I assume that you already have the basics of vaping down. Getting bigger clouds can easily be achieved with an atty that has big air holes, and enough power from your mod. Please be safe and use an ohm reader before slapping the atomizer to your device. Also, get the best batteries your money can buy.
You can order Max VG juices here <removed link> so that you can get monstrous clouds. More VG, more clouds
Vape on!
