Yeah, oil is always nice.

The reason you got a greenish hash last time is because a lot of leaf matter fell through. That could be that you were pressing too hard on the silk screen, or the silkscreen you're using didn't have tight enough stitching in it.

I find making hash with the big, green fan leaves is not as plentiful as making oil. There isn't a lot of vvisable trichs on fan leaves, but making oil with them, the chem. soaks in the fan leaves, ensuring you get what inside of the leaves.

The best trimmings for hash are those little snippetts you get from manicuring the buds. Those trimmings have visable trichs on them, trichs mean hash, so I find those are the best to use.
