can we grow Tomato or Tulsi just with Coco peat ? | Vegetable gardening | GEEKGARDENER

HI I am very new to gardening, just wanted to check , can we grow Tomato or Tulsi just with the Cocopeat in the Pots without the Redsoil ?

Can Cocopeat be the complete replacement for the Redsoil for Terrace gardening ?

i have learnt that Cocopeat does not have any Nutrition in it, so just adding a Organic Vermicompost and some Neem cake with the Coco peat sufficient for growing Tomato and Tulsi in the Balconys ?

which one of the below option is more optimum and Recommended

Option 1 : Only cocopeat + vermicompost

Option 2 : Cocopeat + red soil + vermicompost , in this option what is the Ratio's of cocopeat and redsoil to be used ?
