Yeah, make sure it's wet so it doesn't get shocked when it's submersed. It's also nice not having it covered, as you won't have to worry about molding as there should be enough air flow without plastic wrap.
yes, they are. I don't know how they got in there.
This is my windowsill Glosso. They grew emersed indoors for 5 weeks, and I took off the plastic wrap and put them at windowsill last week. They are doing ok under direct sunlight with no cover. Will see how it goes.
