Voodoo juice is a hydroponic product so it could very well contain sterilizers...or not... so I would stay away from that in organic living soil unless you research it really well to make sure. That being said, I really know nothing about it so it may be fine. Just be careful is all. The GW myco is fantastic. Endo myco is for vegetables and ecto is for trees, generally speaking, and internet science cant really answer if that is 100% true but one certainly wont cause harm if its not needed, and its nature in a bottle so I would guess a mix works best. I use a different brand but more or less identical. The microbes that it comes with are the main strains that mine most of your NPK and being mixed in with the fungal spores it sets up the underground biosphere really well with the fungii linking to the roots and housing the bacteria. 7-10 days later you will see a huge beautification in your plant. I refer to it as "Linking to the soil". I find that dusting a wet rootball at uppotting is the best bang for your buck long term but sometimes for whatever reason a plant doesnt link up. For that I mix 1 tablespoon, which is costly, to 1 litre of water and slowly pour it into the soil in the direct area where the old rootball meets the new soil, and then outwards into the new soil. Water your plant to full runnoff 1st, then let it drip til it stops, then add the myco solution and let it sit completely saturated for a few days until its quite dry but not yet quite ready for water. Then spray the soil with water daily to keep it a bit damp and try not to flood water again for 10 days, but dont let it go dry either. Somewhere in that 10 days you usually notice stalks get fuzzy, leaf stems especially, and a darker healthier green develop, followed by an explosion of growth. I find that cheaper brands of myco really dont work very well when compared to the expensive stuff. Myco is by far my favorite ingredient. In container growing it IS the wow factor. In the garden its less noticable because nature has already dusted the planet in myco.
