A paludarium project

[Robert]

it's not necessary to let the sphagnum moss half submerge in water, as long as it touch the water level up pulling of water or capillary action will ensure sufficient supply to the plant. The sphagnum shouldn't be wet but moist else roots will rot. Are you mixing sphagnum with perlite or sand to ensure laeration and well drain ? How do you hold the media in place-with plastic mesh?
