Oh BTW the tree root measures about 10 and a half or 11 inches and is approximately 7 inches wide so keep that in mind when you go to build my enclosure is 12" high by 8" but its plenty of space for a tarantula. I went bio but only used 1 plant that had 2 separate root systems. I didn’t bother with smaller plants or ground cover because the curtain web will just blanket everything in silk anyway. I just added springtails and isopods to keep everything tidy and healthy. I am installing an automated watering system in all my bioactive builds.
