Weezard:

Here are the original instructions:
Grass method:

Due to the difference in THC strength, you’ll need to use 1.5 grams of good quality well cured bud in order to match the potency of 1 gram of hash or kief. Firstly, remove any stems, seeds or obvious leaf material* then grind to as small a grain (powder) as you can manage, then just follow the rest of the steps as detailed below.

Is it me, or is this not clear whether you use 1.5 and remove the stems, seed, leaves which would leave you with X grams - or if you start with more to end up with 1.5 pure?
