Simple question. What is the best/easiest Extraction Tek for a n00b to perform? Looking for something relatively easy (no chemistry classes ever here) that produces good and relatively high yeilds of spice. Also interested in knowing just how to adjust for lesser quantities of MHRB so that it isn't all waisted if a screw up is encountered. What is the least amount that is worth the time? Especially when learning and doing for the first time. How essential is it to have something to measure the PH? Is there a sure fire way to get the proper measurements w/o having to adjust in order to get PH where it should be at various stages?
