I would say ~15-30min in the morning while getting ready for work since the lights and misters are on timers. About 30min-1hr at night just tending to various tasks, feeding and showering 3x per week. Not to mention the countless hours just sitting and watching! :D

Since you might be collecting fallen branches in leaf litter; I typically take a dremel and remove all bark, soak in a 10% bleach solution for ~10min, then rinse with water before placing in enclosures to keep any stray spiders from hatching. Just my 2 cents.
