Yes I believe you would as Pro Mix from waht I read has no nutrients in it at all.

And Scotts potting soil have 0.14- 0.14 - 0.14 (I believe)

Could anyone with more experience clear this up Im sure many people would love to know.


thanks for the help so far though Now I know exactly what I am looking for. All the store keep trying to puch COCO on me. I found the Coco to stay wet for so long long enough that I felt my plants stayed water logged in my first grow.

kdspecial Reviewed by kdspecial on . PRE MIX SOIL OR MIX MY OWN??????? This will be my second attempt at growing first one was ok. Alot of learning. I was wondering what everyones opinion is about soil mediums? Should I mix my own or buy store made soil And if so what should the NPK of the soil be at? so I dont over add nutrients? Should I mix 1/3 Perlite 2/3 Coco? and Dolomite Lime for balancing Or go 1/3 PeatMoss 1/3 Perlite 1/3 Varmiculite (as seen in High times video Ready Set grow) Should I add Lime to this Mix? Or will its Ph be ok? Or buy Store Rating: 5
