Acquire and clean out the enclosure of any debris
Create the background (if desired)
Waterproof seal anything that will touch moisture that shouldn’t
If you used spray foam for the background, be sure to seal it with silicone for waterproofing
Add the drainage layer (if desired) and guard
Add the base substrate
Add sphagnum moss
Add leaf litter
This may be things like branches, rocks, and more
Tall plants typically go in the back of the enclosure, and short plants go in front
Test the humidity to make sure your humidity is holding as it should for your reptile
Dump the entire springtail culture onto the substrate
They will likely dive underground quickly - do not be alarmed if you do not see any after initially adding them
A difficult but very important step - this allows two key things:
The springtails population must establish to keep up with the inevitable mold levels
The plants need to establish roots so they aren’t easily uprooted or trampled
Be certain that humidity levels are appropriate, and make changes as needed such as adding substrate or increasing the amount of water added to the enclosure
Just like the springtails, the isopods will need to establish their population to keep up with the reptile’s waste production and dead plant matter
