today is your lucky day.. not many people, well that I have came across actually use greensmoke.. its too expensive etc blah blah.. I started with greensmoke and started searching for some customization for it when I realized its virtually impossible.. hence duckysboo boo comment. suggesting to go somewhere else.. let me tell you that there is nothing that comes close to green smoke. I originally thought it was there carts.. which are great.. but in all honesty that was not what makes greensmoke so good.
Here is why today is your lucky day, I have found the perfect setup for the greensmoke that will keep you married to greensmoke forever lol.. This setup is a bit tedious to get going only becasue I have not found a supplier who carries everythign you need. Some come close, but it is cheaper to spread your financial love here.
The setup consists of greensmoke battery, an adapter, and ce3 bottom coil. for those who do not have a greensmoke battary, that means you need to order each from separate vendor. For me, being greensmoke user already have 5 batteries and dont want to wast more money getting others that do not perform like the greensmokes batteries.
the adaptor is 3 bucks for 2 and the ce3 are 10 bucks for 5. You will not regret looking into this setup and you will see what I am talking about when I say that what make greensmoke so good is there battery. Sounds weird because they all look so similair, but the life of the battery is superior to any equivalent on the market.
Your probably like I was and have been searching on the web for proof of what I wrote. I literally have not seen any pictures or videos representing greensmoke batteries with other products. Here is my proof

I hope this at least give you hope that you can indeed use your greensmoke with almost everything on the market..
