Cleaning & maintenance schedule

Daily

  • Mist 1–3 times to keep humidity in range; glass should clear partly between mistings.
  • Check temperature – most tropical species are stressed above 27–28°C.

Weekly

  • Feed and remove uneaten food.
  • Check the drainage layer through the glass and remove water before it reaches the soil.
  • Prune plants that block the front glass.

Monthly

  • Top up leaf litter as it breaks down.
  • Check springtail and isopod numbers; reseed from a culture if they look sparse.
  • Clean misting nozzles and wipe light covers.

Yearly

  • Refresh the top few centimetres of soil in open areas.
  • Replace UVB bulbs (if used) on the manufacturer’s schedule.
