I'll be taking dmt for the first time soon, with my gvg. The gvg has some weed in it, basically I'm wondering if the dmt is placed on top of any amount of weed ( or any bed for that matter ) does it matter? Or does the dmt vaPe first and still give the same effect?

It's better to have a bed of herbs or multiple screens because the spice will melt and you want to be able to catch it and vaporize it before it melts into the gvg.

So 3 screens alone should do it? Also, the heat generated by a slow burning hemp stick, would that do the trick? Don't want to waste my first hyperspace ticket

3 screens or more. I don't know how many GVG people use. Your hemp wick idea isn't going to work. Use a bic or a torch. Don't get sad if you don't do it properly the first time. It takes practice to get used to this and learn how to do it properly.

I currently have 5 screens in my GVG and that works great.
