Hi @sunscape both hydroponics and aeroponics are areas of interest for me.
So nice of you to have shared this information that users can follow to improve their own aeroponics system. Using sponge is much better than those plastic cups.
To spread the word about your post I have created a leo thread

Doing so even you can increase exposure to your post and earn additional leo tokes.
Hope this helps
