Highly recommend everyone use Plant Success mycorrhizae, they use the widest variety of beneficial microbes to feed your plants roots. Their liquid myco Orca is optional, but their Great White powder myco is a must have for germinating and transplanting.
Also recommend every grower try implementing Silica as it strengthens your plants cell walls. A lot more sturdier roots and branches, helps fight off disease and allows for greater nutrient absorption. The one I used is liquid Power SI.
