yeah, add the dolomite lime to the soil in appropriate amounts, how you going ot formulate the whole mix?
I hear blood mean can burn easy. Dolomite lime does work, I was feeding fish and still 6.5. Works good. I put in 2 handfuls for 15 gallons of soil and no prob. But that was prilled dolomite lime off amazaon. I just bought epsoma dolmite lime from hd and I used less, it looks stronger. The more fine the grade the better it works.
