You need to use a certain amount of weed, in order to make sure that the heat passes through nothing but weed, because if there's a gap where there is less air resistance, it'll pass through that and not hit the weed.

For instance, trying to use a one hitter's amount of weed is not feasible for this reason. It will eventually vaporize, but it's a long and annoying process.
