How to set default conda env $CONDA_DEFAULT_ENV?

First off cool plug-in! Thanks for creating it.

I would like to set a default conda env

I tried adding the line:
export CONDA_DEFAULT_ENV="root"

in .bashrc and .zshrc but that didn't work

I also tried adding:
let g.CONDA_DEFAULT_ENV="root" 
even though I didn't think it would work. 

Is there a way to set a default env so that I don't have to select an env when I start neovim?
