I have had my first hamata for 3 months now. It has made about one new pitcher a month but never keeps more than two. I'm hoping one day it will make a rosette like I see in the pics. There are two probs I'm not sure what to do about. I don't think they are major problems but just annoying. Here's my hamata right now.
Hamata 3 months by Thagirion3, on Flickr
First off it's green. When I got it the two pitchers it had were beautiful mottled colors of burgandy on a green background. I know this plant gets enough light. Every morning it goes in the window and gets 2-3 hours of sunlight. Then it goes back into my tank where it is under two t8 lamps for a total of 4 bulbs. Two are cool white bulbs and the other are daylight bulbs of 6500k. Temps are as much as 80 in the day and nights are 50-52F. Humidity is around 70%-90%. Here's the other problem.
Toothless hamata? by Thagirion3, on Flickr
The latest pitchers seem toothless. When I look at this pic full size I see little ridges so it did try to make teeth but not as defined when I first got it and it has smaller pitchers. Yes it is a hamata and not a tentaculata. It had beautiful teeth when I first got it.

Here's the previous pitcher that without the camera also looks toothless. Other than that it seems very healthy and growing at a steady pace. It's just annoying that it's a hamata with no teeth.
