advice on creating hydro-setup for emersed aquaticplants.
 

Hi

I have a emersed setup for aquatic plants. This means that I need high humidity, but not too high, as fungus will grow.

I'm having trouble finding the correct 'settings' for my setup.

I have a setup with a lid, to keep humidity up, but too high humidity will also trigger the plants into setting submersed leaves..even though the plants are emersed.

Does anyone grow aquaticplants here?
or have any good advice on how I should setup my little hydroponics setup?
