I made the humidity trays in the attached photo. They're working pretty good, keeping the temperature around the orchids about 25 degrees less than before I made them however in mid-afternoon at the hottest part of the day my humidity meter shows it to be 16%. Other than that 2hr or so period the humidity stays about 35% on up. I'm misting all of them (these are the ones I discussed in the thread 'Rescued Mothers Day orchids') a couple of times daily at least and they all seem to be getting new leaves. They're getting watered/fed weekly or if the skewers I have inserted in them seem dry. They trays are kept full and in fact a little above the large area where the pots sit on. Anything else I can do to make these better or is this about all I can do?
