Lightbulb vaporizer question.

[CanaBliss]

I am in the process of making a lightbulb vaporizer and I was wondering why do u use 2 straws? Don't u just need one to suck the THC up? Or is it one straw and something else?

[Pichacho]

you need a second hole or something to allow fresh air to get into the bulb, or else you'll be sucking up your weed when you hit.

But with such little space the lightbulb gives, wouldnt u suck the weed up anyway when the second straw brings air into the bulb, forcing it to move and then u'd suck it up? Or u must suck really lightly huh?

[andy704]

yeah you gotta suck really lightly, i sucked up some myself

[CanaBliss]

Aight, well so u must obviously use one of these so how does it work eh? How long should I leave the lighter on the bulb?
