This information is gold!
As someone who grows plants and also 3D prints, I think I've found something really awesome by stumbling onto your post and am very thankful for this information!

I'm going to reblog this so others will see, and also so I can refer to it as a resource in the future.
When I try this out can I tag you in the post to give credit for you helping me discover this electroculture method?

Thanks so much for taking the time to put this together for us!
