Going to need to buy one or the other soon, looking for comments, suggestions, etc. Only interested in these 2 soilless mixes. Always thought these 2 products were the same, I see they are not. I have included "spec" sheets of both products. Not sure if I am understanding some of the numbers correctly.
First thing that caught my eyes is the PH of S.S#4 out of the bag( 4.6-5.2). After a 14 day soak, it came up to 5.5-6.5. I'm assuming that's cause the lime has been activated. This stuff comes with a wetting agent, shouldn't the lime be already activated? I see the ProMix PH seems more better( 5.2-6.2, with 6.2 after a 7 day soak)
So does this mean if you are using S.S.#4, you should soak and let cook for 2 weeks?
Also see in S.S #4 there is fuck all for "P", more Mg, more Sulphur, way less "N" than ProMix Hp. Water holding capacity number is lower, which, if I am understanding correctly, means it drains better?
