First, its nice to meet another grower who knows the secret of growing lies in the rootzone, that sets alot of growers apart imvho.
apart from nutes, this is what i will always have in the mixup.
Great white shark-mycorrhizae & Trichoderma
Hygrozyme
Sweet or molasses.(feeds beneficials & does nothing for enhancing flavor)
other Hygrozyme types work well too, Sensizyme by advanced, Cannazyme by Canna ect.. Their beneficials are great too. gl
