    WAtering the floor down DOES make a big difference. I have a pea gravel floor in mine and it gets soaked frequently everyday, the water evaporating from the gravel makes humidity skyrocket to perfect levels for the plants. Before I started misting even my N. truncata was reluctant to pitcher!

    You said you already have a swamp cooler? To me, it seems that it keeps the humidity about 1/2 the minimum, just get another one. I have also found that a steam humidifier raises humidity a lot more than a swamp cooler, though it does raise the temps a bit.

    NG is spot on.

    With an appropriate base wetting the floor down is fantastic for maintaining humidity.

    On the advise of a local glasshouse manufacture/installer I run what is called here in Aus. 7mm Road Base or Black Metal. It's the gravel they add to tar for making roads. The black absorbs heat, the density of the gravel is good for holding heat (both good in winter) and the large surface are (when wet) helps with humidity maintaining humidity.

    Only on the hotter days once temps get up over say 30C will the misting system come on.

    Itís very easy to automate the wetting down of the gravel with a simple garden sprinkler system and a cheap tap timer. In winter I set it to spray for 1 minute 2x per day and summer 4+ times per day.

    Aaron.
