I've been trying dry-start method for Hemianthus Cuba as a carpet and other plants attached to a driftwood - Christmas moss, Java fern and Anubias Nana.
All the plants are doing great, except HC, which after the initial growth is stunned and older leaves are turning brown as on the photo:
Light: about 25 (measured with PAR meter) at the soil level.
Soil: three inches of Aquasoil
Water and humidity: water is about 2 inches from the surface. It used to be half inch below surface, but I lowered it, thinking its too wet.
I have a 'hot' humidifier running for 5 minutes every 12 hours. I suspect it has something to do with humidity and turned it down just for twice a day, but don't see much improvement (after 2 weeks).
Any suggestions? Shall I take humidifier out completely?
