i wouldn't bother with the starter stuff except for seedlings or if you have hot soil i would maybe mix it in to weaken it. all i have ever grown in is seeding soil fed with foxfarm grow big and later tiger bloom and i have had the ugliest plants you have ever seen. basically its like making your own soil the way i see it.
michaelpeg Reviewed by michaelpeg on . trying to save seedling starter soil... is there anything that I can add to a seedling starter mix that would make it suitable for when I transplant to a pot? I have a lot of leftover mix that I'm never going to use so I figured I might as well try to save myself some money. I was thinking maybe some more perlite plus worm castings or bat guano (I'm not using any other fertilizer)... Rating: 5
