Wow very interesting, I use fox farms, but switched from worm casting to a fox farms compost mix with (worm casting, alfalfa meal, kelp meal, and various ather microbe nutrients), then perlite break down for easy dry out and thats it, I do agree with cheap soils being packed with eggs and pest for sure, and still when I was mixing just worm castings in my mix the results were explosive, this compost from fox is pretty new and my hydro store recomended saying it is full of good stuff, better than just worm castings, so I will let all know how it does because this is my first mix with it..............
