Orchids love extra humidity and this classic size humidity try will do the trick. At 10" x 13" it's small enough to fit almost anywhere and big enough to hold a number of smaller orchids, or a few larger ones. Tray is made of black thick plastic, with a removable grid which keeps orchid pots above the surface of the water. No more trying to wash gross slimey pebbles from a pebble tray! Our humidity tray only has two pieces, and both are easily washed, should they need it! I actually know someone who puts their in the dishwasher, but I'm not sure I recommend this (and it's not in any manufacturing material!) These trays look nice despite being plastic. They are well made and their dark color helps them blend into surrounding decor. Not at all offensive in appearance!
