I've never had any experience growing terrarium plants out from seeds, but I would recommend trying seeds from tropical plants that tolerate a lot of moisture and humidity.I'd like to start a few plants from seeds in my closed terrariums. Is this possible and which type of seed would you recommend? Also can succulents be kept in closed terraniums?
Thanks for any help.
I doubt any succulents could be kept long term in sealed containers due to the high humidity.
