For the last few months I have just been keeping 7 raw prespray boosters and ingredients with me and only mixing up what I need for the job at hand. Very satisfied with using just enough of what I actually need for the fiber and soil type. It's become almost automatic with a cursory look to formulate the right prespray. Not for everyone for sure, but wished I had done it sooner and it leaves accountability for results right where it belongs anyway, on my shoulders.
Wait so you’re just mixing up your own prespray?
