You need to loosen it up more w/ extra pearlite / vermiculite and add hydrated lime to make the ph stable .

Right On!:thumbsup: I use Pro-Mix,the ph is all over the board when your adding ferts to the soil. xcrispi,is right! The lime does the trick! I use this in outdoor grow sites.
GaGrown Reviewed by GaGrown on . ProMix HD Soil ?? I had problems with PowerFlower last year and was looking to change my outdoor soil. I was told about a soil called ProMix HD by Premier Horticulture. Anyone ever hear of it, if so can i get some info on it, and if anything needs to be mixed or if i can just plant right into it.
