Kellogg's has been around for decades(70+ years ago started in orange county, ca). I heard sometime in the past 2 years or so this company was bought by SunGro Horticulture in of British Columbia.
Sun Gro makes the Sunshine Mixes, Black Gold Potting Soils and amendments, etc. They're the largest packer of soils in North America. Good stuff from what I have seen.
High quality standards and ingredients.
How subcool can call it his soil mix, when he has people using
store bought soil as a base? All the guy is doing is adding a few amendments to somebody else mix and calling it his own. Laughable at best.
You make his "supersoil mix", then you let it set for 30 days(just like any organic mix).....at transplant, fill 30-50% of your pot with the supersoil, filling the remainder with base soil (Roots organics, Fox Farm
Ocean Forest, etc. wtf?)
Once you learn about organics his mix becomes even more funny. What I find unbelievable is the amount of people that rant about and buy into this junk.
Go buy some Canadian sphagnum peat moss. The best stuff is readily available and very cheap. Most hardware here in AZ have the Premier brand, wallfart has it as well its called greensmix. After that, I would go with something like this:
40% peat
30% perlite or rice hulls(farm store a lot cheaper)
30% EWC (make sure its high quality, not cardboard and newspaper fed worms.)
Once you got that mixed, all of the other amendments would be added based on the total volume on hand of soil\fert. I prefer the Espoma plant tone over the kellogg but both are good(tomato, citrus or vegetable tone).
To each 1 c.f. of potting soil I add the following:
4 - 5 cups of Canadian Glacial Rock Dust or Azomite
1.5 cups of a mix I make up that consists of equal parts of kelp, neem and crab meal.
Yours would look like per 1 c.f
3-5 cups of mineral Glacial rock dust or azomite
1-3 cups kellog or espoma plant tone
Water on most days with a weekly application of some botanical tea - Comfrey, Yarrow, dandelion.
Nutrient teas are welcome as well, kelp, alfalfa, etc..
Actively aerated compost tea(ACT\AACT) once in veg, once at the beginning of flower for your microbes
Youll be more then rocking and on your way as long as you got your light and air circulation taking care of.
Im still confused why people are using more expensive, inferior products to what they could make themselves for pennies on the dollar.
Hope to have helped some.
