I know everyone is thinking "not another MFL question". This one is a little different because it is involving the grinder and how fine the bud needs to get. I am ordering it from puff it up and it comes with a free 4pc grinder. Im not sure on the quality of the grinder and really dont want to buy a 2pc just for my vape because i do want a good kief collection. here is the link: www.PuffItUp.com If anyone uses the grinder received from this site please tell me how well the grinder works and if i hold it upside down how fine will my herb get.
I don't know if that site is legit, just go to vapeworld or BlissSville. For the Launch Box(and most other vapes) you should have very fine ground bud. You must get a QUALITY grinder, a 2 piece is ideal. Certain cheap/crappy grinders can be dangerous. If you get a 2 piece Space Case then it'll last forever. A Space Case and LB is like a setup that'll last a lifetime.
Like NYCdeisel said, I´d recommend a 2-pc Space case to go with the LB. 4-pc grinders just don´t do the job as good. Or you could get a 4-pc, grind up the weed, salvage the kiefe, regrind the weed in the 4-pc without the kief section upsidedown. Know what I´m saying? it could get you a better grind. But I´m not entirely sure on that.
