Help me buy some more bags.
Hello all. I purchased a set of bubble bags last year and since I was low on money at the time I picked up the 3 bag kit (Blue, Yellow, Purple). I've gotten my use out of the bags (they've paid for themselves) and I'm only getting better and better at achieving full melt. However in my situation the plant material that I deal with is grown outdoors and usually carries with it hidden dirt.
I want to buy 2 more bags, mostly to help filter out this dirt from reaching the 73u bag. I was thinking of getting a 190 and 160, but could dirt still make its way through ? Would it be better to get an even smaller screen ? 190 and a 120, or even 90 ? I'd like to hear what the pro's think. Thanks.
