the humidity tray seems nice but will probably do little to raise the ambient humidity in the room where your orchids are growing. most home grown chids do well with humidity that is comfortable for humans 30-50%. the cheapest way i have found to provide humidity good for all is to use a cheapo sunbeam or whatever steam vaporizer for several hours a day. as cynthia said i too mist in the morning, if i do at all. most have an automatic shut off and are inexpensive $10-15. i have shelob it bloomed twice this year. it seems to need time to acclimate to the new enviornment. i don't mess with the roots.they can sulk for a loooong time. hope this helped
