hi, i recently bought a small maidenhair fern. I try to do my research before i buy any plant so i understand that maidenhair's LOVE moisture. I planted it in a terrarium, and it has only been in there for about 3 days now, but the tips of the fern are now starting to turn brown...not crispy brown, but like a soggy brown. Is it a case of too much moisture or not enough????? Any help i can get is majorly appreciated!!!! thanks so much ps. if you know alot about all ferns... maybe you can give me some growing tips about my button fern and bears paw fern as well.... thanks again
