Growing plants emersed question

For the summer, I have decided to start an emersed tank. I am starting with a three gallon tank, and if all goes well, I will upgrade to a seed starting tray and dome or a ten gallon setup. I plan on mainly growing Cryptocorynes. How do I keep the humidity at around 90-100%? How can I regulate the temperature?

For most Cryptocorynes, that humidity is too high.

However, if you want to get that high, simply put a heater in with the water and put a lid on the tank with very little venting. The glass should be wet in no time.

Snapple,

I doubt that is 90%. Do you have a guage in there telling you so? 90% Humidity would have the entire dome pretty much dripping, the leaves would be wet, trays would be soaked....

The tray has 2" of water in it, heated by a seedling mat to the low 80's and the lack of water on the leaves is because they were left open to dry off for the pic so you could see leaves, not reflections. The dome was left off as well for the leaves to dry and put back on with the pic taken so you could see in.
There is no gauge, but there is a Hygrometer, and the wire is the sensor for the temperature controller. and yes the first ones are wendtii tropica
if you look closely you can see the dried water marks all over the pots from where they are normally all dripping wet.

Also condensation is temperature differential, not humidity, humidity comes from the evaporation of the water heated by the seedling mat under the tray, not from condensation on the dome, thanks.

Great looking crypts, indeed. Is the seedling mat itself consist of a substrate material or are you using a seperate substrate. If using a seperate substrate, what exactly are you growing them in. Thanks.
