I have been waiting to purchase this and finally have created the Terrarium of my dreams. If you are buying this than you probably will be able to figure everything out as the instructions and guide is a little anemic. I will say that you need to treat the acrylic orb as if it is the lens of a fine camera. In prep for ordering, I watch a lot of videos regarding the Bio Orb, a few mentioned how easy it is to scratch. I will tell you that it is way easier than you think. When preparing for planting and setup I wiped the inside of the orb with a clean but old and scraggly washcloth. It is cotton, albeit old - it is still a cotton cloth and it scratched the orb. Turn it to the back side and move on, but seriously don't let something stupid like a huge smearing scratch ruin your orb. Be careful.
