Im going to start this topic as a newcommer. A very annoyed newcommer. You see, i have a problem. I can grow some plants very well, and others very suck. The weirdest thing is, its usually easier plants that i end up killing.
My plants are in a 20L tank with three flourecent terrarium bulbs no more than a foot above the plants (at most). I have a glass cover that the lights sit on that i keep open about two inches to let some air in and out. The humidy hovers between 45 and 85% (usually around 60%). The temperatures have been fluctuating, but mostly between 50 and 85 degrees. I mist the asian pitcher plants and the sun pitcher every night and a couple of times a day to keep the humidity up. I use reverse osmosis water and the lights are on for 15 hours a day.
As for the plants that i have grown successfully;
N. Ventricosa (both normal and 'red')
Dionaea Muscipula typical
H. Heterodoxa x Minor (new, but seems to be doing ok)
N. Gracilis var nigrapurpurea (again, new but doing ok)
D. Scorpidos (some problems at first, but now doing well)
D. Zimbabwe (Hasnt gorwn much, but hasnt died either)
S. Alata (young enough to fit in the terrarium)
Now for the bad list for whatever reason, these plants didnt work;
D. Capensis (tried several times, with several plants. The gorwing head turns grey, than dies and spreads)
D. Regia (was doing very well for a while, gorwing in spurts, than it just stopped and died, though i have been told that they can come back sometimes)
D. Aliciae (i seem to have problems with small rosette sundews)
D. Borneo 8
D. Sessilifolia (both of these apear to be on their way out)
S. flava (might make a recovery, i changed some things)
If you have any thoughts, or if your in the same predicament, let me know. I morn the plants greatly (esspecially the d. regia. I loved that plant... little nice guy). My only thought is that it might be a bad infestation of soil knats. I have been told they are relativly harmless to most plants. But the ones i was talking about were mostly young plants that might have been overwhelmed. To counteract this i have tried moving sundews and pings closer to the infected pots, in the hopes that the plants would eat the adults.
any thoughts? Let me know.
