I read your article on how to make the growing mix and found it very helpful. I am a big fan of pumice, as it does not float like perlite tends to do when I add water.

I watched a video saying sundews do better outside in the sun than they so indoors by a window, and it totally flopped. I had I it in a shady nook by a shrub in late Spring, and it looked like the sun steam cooked it one day.

Next time, I might start over and try your grow mix, and use a jar to build a mini terrarium. I seem to get a lot of success rehabilitating plants under cool, bright, humid conditions.
