what micron do you guys think is best? i have a nice silk screen 120micron cloth i could use, or i have the 50 micron stainless steel screen that came with my blasting tube. what do you guys think?
It depends on what you price range is. You could get a vacuum pump (5cfm - 7cfm), with a metal desiccator off ebay for 300 - 400 tops. Or a vacuum pump with a vacuum oven for 2k. Hope that helps!

I would be using both.... throw the 50 micron steel screen undernieth the 120 micron cloth. The 120 alone would let plant matter in, & the 50 alone would leave room for error. By that I mean there is still a chance that the screen will blow out, & you loose a full run. You could make the 50 micron screen work with a clamp; but I always play it safe =)
