Firstly check that your flower is ground into a small enough particle size to fall into the holes in the Home Fill System. Secondly, you should not be pouring all of the ground flower into the cavity at once. Instead, pour enough flower until it reaches the top then. Then use the spatula provided to smooth the flower out and then tap the Home Fill System firmly on a surface so that the ground flower falls into the holes and then into the Flowersticks lined up beneath them. Then add more dry herb and repeat this process until the holes are filled to the top. It is ok if you don't get the full 2 grams of flower in.
