Well, went to Petco yesterday and picked up some Java moss and Java fern. Separated some fern rhizomes single and multiple and set them on wood and rock. Old shaky hands can't tie them to these decorations, so will hope they take hold by the time dry start is ready to flood (2 mo.?) Also got a "wreath" of moss, which I am pulling pieces off and again lying on rock and wood. I think humidity is as close to 100% as I can get it. Surrounding room temp is 72º and sides of tank, as you can see, are dripping. Water still not up to level of Carib substrata but everything fully moist. All looks pretty healthy so far. Would like to get some pennywort (rotundifolia) to add as well, then, that should do it for dry start plants. With the humidity so high, I wonder if I should leave saran wrap fully covering the tank.
Here is a picture of the installation this morning.
